Section 1

General provisions

1.1 Introductory note

It should be noted that other international and national regulations exist and that those regulations may recognize all or part of the provisions of this Code. In addition, port authorities and other bodies and organizations should recognize the Code and may use it as a basis for their storage and handling bye-laws within loading and discharge areas.

1.2 Cargoes listed in this Code

1.2.1 Typical cargoes currently shipped in bulk, together with advice on their properties and methods of handling, are given in the schedules for individual cargoes. However, these schedules are not exhaustive and the properties attributed to the cargoes are given only for guidance. Consequently, before loading, it is essential to obtain current valid information from the shipper on the physical and chemical properties of the cargoes presented for shipment. The shipper shall provide appropriate information about the cargo to be shipped (see 4.2).

1.2.2 Where a solid bulk cargo is specifically listed in appendix 1 to this Code (individual schedules for solid bulk cargoes), it shall be transported in accordance with the provisions in its schedule in addition to the provisions in sections 1 to 10 and 11.1.1 of this Code. The master shall consider whether to consult the authorities at the ports of loading and discharge, as necessary, concerning the requirements which may be in force and applicable for the carriage.

1.3 Cargoes not listed in this Code

1.3.1 If a solid cargo which is not listed in appendix 1 to this Code is proposed for carriage in bulk, the shipper shall, prior to loading, provide the competent authority of the port of loading with the characteristics and properties of the cargo in accordance with section 4 of this Code. Based on the information received, the competent authority will assess the acceptability of the cargo for safe shipment.

1.3.1.1 When it is assessed that the solid bulk cargo proposed for carriage may present hazards as those defined by group A or B of this Code as defined in 1.7, advice is to be sought from the competent authorities of the port of unloading and of the flag State. The three competent authorities will set the preliminary suitable conditions for the carriage of this cargo.

1.3.1.2 When it is assessed that the solid bulk cargo proposed for carriage presents no specific hazards for transportation, the carriage of this cargo shall be authorized. The competent authorities of the port of unloading and of the flag State shall be advised of that authorization.

1.3.2 The competent authority of the port of loading shall provide to the master a certificate stating the characteristics of the cargo and the required conditions for carriage and handling of this shipment. The competent authority of the port of loading shall also submit an application to the Organization, within one year from the issue of the certificate, to incorporate this solid bulk cargo into appendix 1 of this Code. The format of this application shall be as outlined in 1.3.3.

Section 2

General loading, carriage and unloading precautions

2.1 Cargo distribution

2.1.1 General

A number of accidents have occurred as a result of improper loading and unloading of solid bulk cargoes. It shall be noted that solid bulk cargoes have to be properly distributed throughout the ship to provide adequate stability and to ensure that the ship’s structure is never overstressed. Furthermore, the shipper shall provide the master with adequate information about the cargo, as * specified in section 4, to ensure that the ship is properly loaded.

2.1.2 To prevent the structure being overstressed

A general cargo ship is normally constructed to carry cargoes in the range of 1.39 to 1.67 cubic metres per tonne when loaded to full bale and deadweight capacities. When loading a high-density solid bulk cargo, particular attention shall be given to the distribution of weights to avoid excessive stresses, taking into account that the loading conditions may be different from those found normally and that improper distribution of such cargo may be capable of stressing either the structure under the load or the entire hull. To set out exact rules for the distribution of loading is not practicable for all ships because the structural arrangements of each vessel may vary greatly. The information on proper distribution of cargo may be provided in the ship’s stability information booklet or may be obtained by the use of loading calculators, if available.

2.1.3 To aid stability

2.1.3.1 Having regard to SOLAS regulation II-1/5-1, a stability information booklet shall be provided aboard all ships subject to the Convention. The master shall be able to calculate the stability for the anticipated worst conditions during the voyage, as well as that on departure, and demonstrate that the stability is adequate.

2.1.3.2 Shifting divisions and bins, of adequate strength, shall be erected whenever solid bulk cargoes, which are suspected of readily shifting, are carried in ’tween deck cargo spaces or in only partially filled cargo spaces.

2.1.3.3 As far as practicable, high-density cargoes shall be loaded in the lower hold cargo spaces in preference to ’tween deck cargo spaces.

2.1.3.4 When it is necessary to carry high-density cargoes in ’tween decks or higher cargo spaces, due consideration shall be given to ensure that the deck area is not overstressed and that the ship’s stability is not reduced below the minimum acceptable level specified in the ship’s stability data.

2.2 Loading and unloading

† 2.2.1 Cargo spaces shall be inspected and prepared for the particular cargo which is to be loaded.

* Also refer to the Code of Practice for the Safe Loading and Unloading of Bulk Carriers (resolution A.862(20), as amended). † Refer to Guidance to ships’ crews and terminal personnel for bulk carrier inspections (resolution A.866(20)).

MSC 107/20/Add.2 Annex 9, page 16 2.2.2 Due consideration shall be given to bilge wells and strainer plates, for which special preparation is necessary, to facilitate drainage and to prevent entry of the cargoes into the bilge system. 2.2.3 Bilge lines, sounding pipes and other service lines within the cargo space shall be in good order. 2.2.4 Because of the velocity at which some high-density solid bulk cargoes are loaded, special care may be necessary to protect cargo space fittings from damage. To sound bilges after the completion of loading may be effective to detect damage on cargo space fittings. 2.2.5 As far as practicable, ventilation systems shall be shut down or screened and air conditioning systems placed on recirculation during loading or discharge, to minimize dust ingress into the living quarters or other interior spaces. 2.2.6 Due consideration shall be given to minimize the extent to which dust may come into contact with moving parts of deck machinery and external navigational aids.

Section 3

Safety of personnel and ship

3.1 General requirements

3.1.1 Prior to and during loading, carriage and discharge of a solid bulk cargo, all necessary safety precautions shall be observed.

3.1.2 Routine onboard operational fire safety risk assessments shall be carried out by the ship’s crew for cargo handling areas on self-unloading bulk carriers featuring internally installed conveyor systems within the ship’s structure. Due consideration shall be given to fire prevention and the effective operation of fire detection systems, containment and suppression under all anticipated operating conditions and cargoes. The fire safety risk assessments shall be detailed in the ship’s Safety Management System (SMS) together with a recommended timing to provide regular assessments. * 3.1.3 A copy of the instructions on emergency response and medical first aid relevant to incidents involving dangerous goods in solid form in bulk shall be on board.

3.2 Poisoning, corrosive and asphyxiation hazards

3.2.1 Some solid bulk cargoes are susceptible to oxidation, which may result in oxygen depletion, emission of toxic gases or fumes and self-heating. Some cargoes are not liable to oxidize but may emit toxic fumes, particularly when wet. There are also cargoes which, when wetted, are corrosive to skin, eyes and mucous membranes or to the ship’s structure. When these cargoes are carried, particular attention shall be given to protection of personnel and the need for special precautions to be taken prior to loading and after unloading.

3.2.2 Appropriate attention shall be given that cargo spaces and adjacent spaces may be depleted in oxygen or may contain toxic or asphyxiating gases, and that an empty cargo space or tank which has remained closed for some time may have insufficient oxygen to support life.

3.2.3 Many solid bulk cargoes are liable to cause oxygen depletion in a cargo space or tank. These include, but are not limited to, most vegetable products and forest products, ferrous metals, metal sulphide concentrates and coal cargoes.

3.2.4 Prior to entry into an enclosed space aboard a ship, appropriate procedures shall be followed, † taking into account the recommendations developed by the Organization. It is to be noted that, after a cargo space or tank has been tested and generally found to be safe for entry, small areas may exist where oxygen is deficient or toxic fumes are still present.

3.2.5 When carrying a solid bulk cargo that is liable to emit a toxic or flammable gas, and/or cause oxygen depletion in the cargo space, the appropriate instrument(s) for measuring the concentration of gas and oxygen in the cargo space shall be provided.

3.2.6 Emergency entry into a cargo space shall be undertaken only by trained personnel wearing self-contained breathing apparatus and protective clothing and always under the supervision of a responsible officer.

* Refer to Medical First Aid Guide for Use in Accidents Involving Dangerous Goods (MFAG) (MSC/Circ.857) (see the IMDG Code Supplement). † Refer to Revised recommendations for entering enclosed spaces aboard ships (A.1050(27)).

3.3 Health hazards due to dust

To minimize the chronic and acute risks associated with exposure to the dust of some solid bulk cargoes, the need for a high standard of personal hygiene of those exposed to the dust cannot be overemphasized. Precautions, including the use of appropriate breathing protection, protective clothing, protective skin creams, adequate personal washing and laundering of outer clothing, shall be taken, as necessary.

3.4 Flammable atmosphere

3.4.1 Dust of some solid bulk cargoes may constitute an explosion hazard, especially while loading, unloading and cleaning. This risk can be minimized by ventilating to prevent the formation of a dust-laden atmosphere and by hosing down rather than sweeping.

3.4.2 Some cargoes may emit flammable gases in sufficient quantities to constitute a fire or explosion hazard. Where this is indicated in the cargo schedule in this Code or by the cargo information provided by the shipper, the cargo spaces shall be effectively ventilated, as necessary. The atmosphere in the cargo spaces shall be monitored by means of an appropriate gas detector. Due consideration shall be given to the ventilation and monitoring of the atmosphere in the enclosed spaces adjacent to the cargo spaces.

3.5 Ventilation

3.5.1 Unless expressly provided otherwise, when cargoes which may emit toxic gases are carried, the cargo spaces shall be provided with mechanical or natural ventilation; and, when cargoes which may emit flammable gases are carried, the cargo spaces shall be provided with mechanical ventilation.

3.5.2 If maintaining ventilation would endanger the ship or the cargo, it may be interrupted unless this would produce a risk of explosion.

3.5.3 When continuous ventilation is required by the schedule for the cargo in this Code or by the cargo information provided by the shipper, ventilation shall be maintained while the cargo is on board, unless a situation develops where ventilation would endanger the ship.

3.5.4 Ventilation openings shall be provided in holds intended for the carriage of cargoes that require continuous ventilation. Such openings shall comply with the requirements of the Load Line Convention, as amended, for openings not fitted with means of closure.

3.5.5 Ventilation shall be such that any escaping hazardous gases, vapours or dust cannot enter the accommodation or other interior spaces in hazardous concentrations. Due consideration shall be given to prevent escaping hazardous gases, vapours or dust from reaching enclosed work areas. Adequate precautions shall be taken to protect the personnel in these work areas.

3.5.6 When a cargo may heat spontaneously, ventilation other than surface ventilation shall not be applied. On no account shall air be directed into the body of the cargo.

3.6 Cargo under in-transit fumigation

* 3.6.1 Fumigation shall be performed based on the recommendations developed by the Organization.

3.6.2 When a fumigant is used, such as phosphine gas, for fumigation-in-transit, due consideration shall be given to the severe toxicity of fumigants, taking into account that fumigants may enter into occupied spaces despite many precautions taken. In particular, in the case that fumigant leaks from a cargo hold under fumigation, the possibility should be kept in mind that it may enter the

* Refer to Recommendations on the safe use of pesticides in ships applicable to the fumigation of cargo holds (MSC.1/Circ.1264, as amended by MSC.1/Circ.1396).

engine-room via pipe tunnels, ducts, and piping of any kind, including wiring ducts on or below deck, or dehumidifier systems that may be connected to parts of the cargo hold or compartments of the engine-room. Attention shall be given to potential problem areas such as bilge and cargo * line systems and valves. In all cases, ventilation procedures on board the ship during the voyage should be scrutinized with regard to the possibility of drawing in the fumigant gas such as by incorrect ventilation procedures and settings, vacuum creation due to incorrect closing devices or flap settings, air conditioning and closed loop ventilation of the accommodation. Prior to commencement of fumigation procedures, it should be verified that ventilation flaps and closing devices are set correctly and that means of closing and sealing of all the bulkhead openings (such as doors and manholes) leading from the engine-room to piping tunnels/duct keels and other spaces that in case of leaks could become unsafe to enter during the fumigation are effective, confirmed † closed and have warning signs posted.

3.6.3 Gas concentration safety checks shall also be continued throughout the voyage at least at eight-hour intervals or more frequently if so advised by the fumigator-in-charge at all appropriate locations, which shall at least include: accommodation; engine-rooms; areas designated for use in navigation of the ship; and frequently visited working areas and stores, such as the forecastle head spaces, adjacent to cargo holds being subject to fumigation in transit. Special attention shall also be given to potential problem areas such as bilge and cargo line systems. These readings shall be recorded in the ship’s logbook.

* Refer to paragraph 3.3.2.4 of MSC.1/Circ.1264, as amended by MSC.1/Circ.1396. † Refer to paragraph 3.3.2.10 of MSC.1/Circ.1264, as amended by MSC.1/Circ.1396.

4.3 Certificates of test

4.3.1 To obtain the information required in 4.2.1, the shipper shall arrange for the cargo to be properly sampled and tested. The shipper shall provide the ship’s master or their representative with the appropriate certificates of test, if required in this Code.

4.3.2 When a group A cargo is carried, the shipper shall provide the ship’s master or their representative with a signed certificate of the TML, and a signed certificate or declaration of the moisture content, each issued by an entity recognized by the competent authority of the port of loading. The certificate of TML shall contain, or be accompanied by, the result of the test for determining the TML. The declaration of moisture content shall contain, or be accompanied by, a statement by the shipper that the moisture content is, to the best of their knowledge and belief, the average moisture content of the cargo at the time the declaration is presented to the master.

4.3.3 When a group A cargo is carried, procedures for sampling, testing and controlling moisture content to ensure the moisture content is less than the TML when it is on board the ship shall be established by the shipper, taking account of the provisions of this Code. Such procedures shall be approved and * their implementation checked by the competent authority of the port of loading. The document issued by the competent authority stating that the procedures have been approved shall be provided to the master or their representative.

4.3.4 If the cargo is loaded on to the ship from barges, in developing the procedures under 4.3.3 the shipper shall include procedures to protect the cargo on the barges from any precipitation and water ingress.

4.3.5 When a group A cargo is to be loaded into more than one cargo space of a ship, the certificate or the declaration of moisture content shall certify the moisture content of each type of finely grained material loaded into each cargo space. Notwithstanding this requirement, if sampling according to internationally or nationally accepted standard procedures indicates that the moisture content is uniform throughout the consignment, then one certificate or declaration of average moisture content for all cargo spaces is acceptable.

* Refer to Guidelines for developing and approving procedures for sampling, testing and controlling the moisture content for solid bulk cargoes which may liquefy or undergo dynamic separation (MSC.1/Circ.1454/Rev.2).

24

Bilaga

MSC 107/20/Add.2 Annex 9, page 23

4.3.6 Where certification is required by the individual schedules for cargoes possessing chemical hazards, the certificate shall contain, or be accompanied by, a statement from the shipper that the chemical characteristics of the cargo are, to the best of their knowledge, those present at the time of the ship’s loading. However, it is important to ensure that the samples taken are representative of the whole depth of the stockpile.

4.4 Sampling procedures

4.4.1 Physical property tests on the consignment are meaningless unless they are conducted prior to loading on truly representative test samples.

4.4.2 Sampling shall be conducted only by persons who have been suitably trained in sampling procedures and who are under the supervision of someone who is fully aware of the properties of the consignment and also the applicable principles and practices of sampling.

4.4.3 For a group A cargo, the shipper shall facilitate access to stockpiles for the purpose of inspection, sampling and subsequent testing by the ship’s nominated representative.

4.4.4 Prior to taking samples, and within the limits of practicability, a visual inspection of the consignment which is to form the ship’s cargo shall be carried out. Any substantial portions of material which appear to be contaminated or significantly different in characteristics or moisture content from the bulk of the consignment shall be sampled and analysed separately. Depending upon the results obtained in these tests, it may be necessary to reject those particular portions as unfit for shipment.

4.4.5 Representative samples shall be obtained by employing techniques which take the following factors into account:

.1 the type of material;

.2 the particle size distribution;

.3 composition of the material and its variability;

.4 the manner in which the material is stored, in stockpiles, rail wagons or other containers, and transferred or loaded by material-handling systems such as conveyors, loading chutes, crane grabs, etc.;

.5 the chemical hazards (toxicity, corrosivity, etc.);

.6 the characteristics which have to be determined: moisture content, TML, bulk density/stowage factor, angle of repose, etc.;

.7 variations in moisture distribution throughout the consignment which may occur due to weather conditions, natural drainage, e.g. to lower levels of stockpiles or containers, or other forms of moisture migration; and

.8 variations which may occur following freezing of the material.

4.4.6 Throughout the sampling procedures, utmost care shall be taken to prevent changes in quality and characteristics. Samples for moisture testing shall be immediately placed in suitable airtight, non-absorbent containers with a minimum of free air space to minimize any change in moisture content, such containers being properly marked.

4.4.7 Unless expressly provided otherwise, sampling for the test required by this Code shall follow an internationally or nationally accepted standard procedure.

4.4.8 For unprocessed mineral ores, the sampling of stationary stockpiles shall be carried out only when access to the full depth of the stockpile is available and samples from the full depth of the stockpile can be extracted.

MSC 107/20/Add.2 Annex 9, page 24

4.5 Interval between sampling/testing and loading for TML and moisture content determination

4.5.1 The shipper shall be responsible for ensuring that a test to determine the TML of a solid bulk cargo is conducted within six months to the date of loading the cargo. Notwithstanding this provision, where the composition or characteristics of the cargo are variable for any reason, the shipper shall be responsible for ensuring that a test to determine the TML is conducted again after it is reasonably assumed that such variation has taken place.

4.5.2 The shipper shall be responsible for ensuring that sampling and testing for moisture content is conducted as near as practicable to the date of commencement of loading. The interval between sampling/testing and the date of commencement of loading shall never be more than 7 days. If the cargo has been exposed to significant rain or snow between the time of testing and the date of completion of loading, the shipper shall be responsible for ensuring that the moisture content of the cargo is still less than its TML, and evidence of this is provided to the master as soon as practicable.

4.5.3 Samples of frozen cargo shall be tested for the TML or the moisture content after the free moisture has completely thawed.

4.6 Sampling procedures for concentrate stockpiles

4.6.1 It is not practicable to specify a single method of sampling for all consignments since the character of the material and the form in which it is available will affect the selection of the procedure to be used. In the absence of internationally or nationally accepted standard sampling procedures, the following sampling procedures for concentrate stockpiles may be used to determine the moisture content and the TML of mineral concentrates. These procedures are not intended to replace sampling procedures, such as the use of automatic sampling, that achieve equal or superior accuracy of either moisture content or TML.

4.6.2 Subsamples are taken in a reasonably uniform pattern, where possible from a levelled stockpile.

4.6.3 A plan of the stockpile is drawn and divided into areas, each of which contains approximately 125 t, 250 t or 500 t, depending on the amount of concentrate to be shipped. Such a plan will indicate the number of subsamples required and where each is to be taken. Each subsample taken is drawn from approximately 50 cm below the surface of the designated area.

4.6.4 The number of subsamples and sample size are given by the competent authority or determined in accordance with the following scale:

Consignments of not more than 15,000 t: One 200 g subsample is taken for each 125 t to be shipped.

Consignments of more than 15,000 but not more than 60,000 t: One 200 g subsample is taken for each 250 t to be shipped.

Consignments of more than 60,000 t: One 200 g subsample is taken for each 500 t to be shipped.

4.6.5 Subsamples for moisture content determination are placed in sealed containers (such as plastic bags, cans or small metallic drums) immediately on withdrawal for conveyance to the testing laboratory, where they are thoroughly mixed in order to obtain a fully representative sample. Where testing facilities are not available at the testing site, such mixing is done under controlled conditions at the stockpile and the representative sample placed in a sealed container and shipped to the test laboratory.

4.6.6 Basic procedural steps include:

.1 identification of consignment to be sampled;

26

Bilaga

MSC 107/20/Add.2 Annex 9, page 25 .2 determination of the number of individual subsamples and representative samples, as described in 4.6.4, which are required; .3 determination of the positions from which to obtain subsamples and the method of combining such subsamples to arrive at a representative sample; .4 gathering of individual subsamples and placing them in sealed containers; .5 thorough mixing of subsamples to obtain the representative sample; and .6 placing the representative sample in a sealed container if it has to be shipped to a test laboratory.

Trimming procedures

5.1 General provisions for trimming

5.1.1 Trimming a cargo reduces the likelihood of the cargo shifting and minimizes the air entering the cargo. Air entering the cargo could lead to spontaneous heating. To minimize these risks, cargoes shall be trimmed reasonably level, as necessary.

5.1.2 Cargo spaces shall be as full as practicable without resulting in excessive loading on the bottom structure or ’tween deck to prevent sliding of a solid bulk cargo. Due consideration shall be given to the amount of a solid bulk cargo in each cargo space, taking into account the possibility of shifting and longitudinal moments and forces of the ship. Cargo shall be spread as widely as practicable to the boundary of the cargo space. Alternate hold loading restrictions, as required by SOLAS chapter XII, may also need to be taken into account.

5.1.3 The master has the right to require that the cargo be trimmed level, where there is any concern regarding stability based upon the information available, taking into account the characteristics of the ship and the intended voyage.

5.2 Special provisions for multi-deck ships

5.2.1 When a solid bulk cargo is loaded only in lower cargo spaces, it shall be trimmed sufficiently to equalize the mass distribution on the bottom structure.

5.2.2 When solid bulk cargoes are carried in ’tween decks, the hatchways of such ’tween decks shall be closed in those cases where the loading information indicates an unacceptable level of stress of the bottom structure if the hatchways are left open. The cargo shall be trimmed reasonably level and shall either extend from side to side or be secured by additional longitudinal divisions of sufficient strength. The safe load-carrying capacity of the ’tween decks shall be observed to ensure that the deck structure is not overloaded.

5.2.3 If coal cargoes are carried in ’tween decks, the hatchways of such ’tween decks shall be tightly sealed to prevent air moving up through the body of the cargo in the ’tween decks.

5.3 Special provisions for cohesive bulk cargoes

5.3.1 All damp cargoes and some dry ones possess cohesion. For cohesive cargoes, the general provisions in 5.1 shall apply.

5.3.2 The angle of repose is not an indicator of the stability of a cohesive bulk cargo and it is not included in the individual schedules for cohesive cargoes.

5.4 Special provisions for non-cohesive bulk cargoes

5.4.1 Non-cohesive bulk cargoes are those listed in paragraph 1 in appendix 3 and any other cargo not listed in the appendix, exhibiting the properties of a non-cohesive material.

29

Bilaga

MSC 107/20/Add.2 Annex 9, page 28 5.4.2 For trimming purposes, solid bulk cargoes can be categorized as cohesive or non-cohesive. The angle of repose is a characteristic of non-cohesive bulk cargoes which is indicative of cargo stability and has been included in the individual schedules for non-cohesive cargoes. The angle of repose of the cargoes shall establish which provisions of this section apply. Methods for determining the angle of repose are given in section 6.

5.4.3 Non-cohesive bulk cargoes having an angle of repose less than or equal to 30°

These cargoes, which flow freely like grain, shall be carried according to the provisions applicable * to the stowage of grain cargoes. The bulk density of the cargo shall be taken into account when determining: .1 the scantlings and securing arrangements of divisions and bin bulkheads; and .2 the stability effect of free cargo surfaces.

5.4.4 Non-cohesive bulk cargoes having an angle of repose greater than 30° to 35°

inclusive

These cargoes shall be trimmed according to the following criteria: .1 the unevenness of the cargo surface measured as the vertical distance ( h) between the highest and lowest levels of the cargo surface shall not exceed B/10, where B is the beam of the ship in metres, with a maximum allowable h = 1.5 m; or .2 loading is carried out using trimming equipment approved by the competent authority.

5.4.5 Non-cohesive bulk cargoes having an angle of repose greater than 35°

These cargoes shall be trimmed according to the following criteria: .1 the unevenness of the cargo surface measured as the vertical distance ( h) between the highest and lowest levels of the cargo surface shall not exceed B/10, where B is the beam of the ship in metres, with a maximum allowable h = 2 m; or .2 loading is carried out using trimming equipment approved by the competent authority.

Section 7

Cargoes which may liquefy or undergo dynamic separation

7.1 Introduction

7.1.1 The purpose of this section is to bring to the attention of masters and others with responsibilities for the loading and carriage of bulk cargoes, the risks associated with liquefaction or dynamic separation and the precautions to minimize the risk. Such cargoes may appear to be in a relatively dry granular state when loaded, and yet may contain sufficient moisture to become fluid or unstable under the stimulus of compaction and the vibration which occurs during a voyage.

7.1.2 A ship’s motion may cause a cargo to shift sufficiently to capsize the vessel. Cargo shift can be divided into two types, namely, sliding failure or liquefaction consequence. Trimming the cargo in accordance with section 5 can prevent sliding failure.

7.1.3 Some group A cargoes may also heat spontaneously.

7.2 Conditions for hazards

7.2.1 Group A cargoes contain a certain proportion of small particles and a certain amount of moisture. Group A cargoes may liquefy during a voyage even when they are cohesive and trimmed level. Liquefaction can result in cargo shift. This phenomenon may be described as follows: .1 the volume of the spaces between the particles reduces as the cargo is compacted owing to the ship’s motion, etc.; .2 the reduction in space between cargo particles causes an increase in water pressure in the space; and .3 the increase in water pressure reduces the friction between cargo particles, resulting in a reduction in the shear strength of the cargo.

7.2.2 Liquefaction does not occur when the cargo consists of large particles or lumps and water passes through the spaces between the particles and there is no increase in the water pressure.

7.2.3 A cargo shift caused by liquefaction may occur when the moisture content exceeds the TML. Some cargoes are susceptible to moisture migration and may develop a dangerous wet base even if the average moisture content is less than the TML. Although the cargo surface may appear dry, undetected liquefaction may take place, resulting in shifting of the cargo. Cargoes with high moisture content are prone to sliding, particularly when the cargo is shallow and subject to large heel angles.

7.2.4 In the resulting viscous fluid state cargo may flow to one side of the ship with a roll but not completely return with a roll the other way. Consequently the ship may progressively reach a dangerous heel and capsize quite suddenly.

7.3 Provisions for cargoes which may liquefy or undergo dynamic separation

7.3.1 General

7.3.1.1 Group A cargoes shall only be accepted for loading when the actual moisture content of the cargo is less than its TML. Notwithstanding this provision, cargoes having moisture content in excess of

32

Bilaga

MSC 107/20/Add.2 Annex 9, page 31 the TML may be carried on a specially constructed or fitted cargo ship for confining cargo shift specified in 7.3.2. 7.3.1.2 Notwithstanding the provisions in 1.4 of this Code, the requirements in 4.2.2.9, 4.2.2.10, 4.3.2 to 4.3.5, 4.5, 4.6 and 8 of this Code need not apply to a group A cargo provided that the cargo is carried on a specially constructed or fitted cargo ship for confining cargo shift specified in 7.3.2 or on a specially constructed ship for dry powdery cargoes specified in 7.3.3. 7.3.1.3 Cargoes which contain liquids other than packaged canned goods or the like shall not be stowed in the same cargo space above or adjacent to these solid bulk cargoes. 7.3.1.4 Adequate measures shall be taken to prevent liquids entering the cargo space in which these solid bulk cargoes are stowed during the voyage. 7.3.1.5 Masters shall be cautioned about the possible danger of using water to cool these cargoes while the ship is at sea. Introducing water may bring the moisture content of these cargoes to a flow state. When necessary, due consideration shall be given to apply water in the form of spray.

7.3.2 Specially constructed or fitted cargo ships for confining cargo shift

7.3.2.1 Specially constructed cargo ships for confining cargo shift shall have permanent structural boundaries, so arranged as to confine any shift of cargo to an acceptable limit. The ship concerned shall carry evidence of approval by the Administration. 7.3.2.2 Specially fitted cargo ships for confining cargo shift shall be fitted with specially designed portable divisions to confine any shift of cargo to an acceptable limit. Specially fitted cargo ships shall be in compliance with the following requirements: .1 The design and positioning of such special arrangements shall adequately provide not only the restraint of the immense forces generated by the flow movement of high-density bulk cargoes, but also for the need to reduce to an acceptable safe level the potential heeling movements arising out of a transverse cargo flow across the cargo space. Divisions provided to meet these requirements shall not be constructed of wood. .2 The elements of the ship’s structure bounding such cargo shall be strengthened, as necessary. .3 The plan of special arrangements and details of the stability conditions on which the design has been based shall have been approved by the Administration. The ship concerned shall carry evidence of approval by the Administration. 7.3.2.3 A submission made to an Administration for approval of such a ship shall include: .1 relevant structural drawings, including scaled longitudinal and transverse sections; .2 stability calculations, taking into account loading arrangements and possible cargo shift, showing the distribution of cargo and liquids in tanks, and of cargo which may become fluid; and .3 any other information which may assist the Administration in the assessment of the submission.

7.3.3 Specially constructed cargo ships for dry powdery cargoes

7.3.3.1 Specially constructed cargo ships for dry powdery cargoes shall be designed and constructed to: .1 carry solely dry powdery cargoes; and .2 handle cargoes by means of closed type systems using pneumatic equipment which prevent the cargo from the exposure to weather. 7.3.3.2 The ship concerned shall carry evidence of approval by the Administration.

Section 8

Test procedures for group A cargoes

8.1 General

For a group A cargo, the actual moisture content and transportable moisture limit shall be determined in accordance with a procedure determined by the appropriate authority as required by 4.1.4 of this Code.

8.2 Test procedures for measurement of moisture content

There are recognized international and national methods for determining moisture content for various materials. Reference is made to 1.1.4.4 of appendix 2.

8.3 Methods for determining transportable moisture limit

The recommended methods for determining transportable moisture limit are given in appendix 2.

8.4 Complementary test procedure for determining the possibility of liquefaction

8.4.1 A ship’s master may carry out a check test for approximately determining the possibility of flow on board ship or at the dockside by the following auxiliary method: Half fill a cylindrical can or similar container (0.5 to 1 L capacity) with a sample of the material. Take the can in one hand and bring it down sharply to strike a hard surface such as a solid table from a height of about 0.2 m. Repeat the procedure 25 times at one- or two-second intervals. Examine the surface for free moisture or fluid conditions. If free moisture or a fluid condition appears, arrangements should be made to have additional laboratory tests conducted on the material before it is accepted for loading. 8.4.2 If samples remain dry following a can test, the moisture content of the material may still exceed the transportable moisture limit (TML).

9.2.3.1.1 These are materials which, when carried in bulk, possess chemical hazards other than the hazards covered by the classification system of the IMDG Code. These materials present a significant risk when carried in bulk and require special precautions. 9.2.3.1.2 A material shall be classified as MHB if the material possesses one or more of the chemical hazards (excluding those hazards which are covered by the classification system of the IMDG Code) as defined below. When a test method is prescribed, representative samples of the cargo to be carried shall be used for testing. Samples shall be taken 200 mm to 360 mm inward from the surface at 3 m intervals over the length of a stockpile. 9.2.3.1.3 A material may also be classified as MHB by analogy with similar cargoes with known hazardous properties or by records of accidents. 9.2.3.1.4 Although the chemical hazards are intended to be closely defined in order to establish a uniform approach to MHB classification, where human experience or other factors indicate the need to consider other chemical hazards, these shall always be taken into account. Where deviations from the chemical hazards described in 9.2.3.2 to 9.2.3.7 have been recognized (Other hazards (OH)), they shall be properly recorded with justifications. Other hazards are to be included in the section for “Hazard” in the individual schedule. 9.2.3.1.5 A notational reference shall be provided in the “MHB” cell of the Characteristics table for each individual schedule for cargoes classified as MHB. When a material possesses one or more of the chemical hazards as defined below, the notational reference for each hazard shall be included in the “MHB” cell.

Section 10

Carriage of solid wastes in bulk

10.1 Preamble

10.1.1 The transboundary movement of wastes represents a threat to human health and to the environment. 10.1.2 Wastes shall be carried in accordance with the relevant international recommendations and conventions and in particular, where it concerns transport in bulk by sea, with the provisions of this Code.

10.2 Definitions

10.2.1 Wastes, for the purpose of this section, means solid bulk cargoes containing or contaminated with one or more constituents which are subject to the provisions of this Code applicable to cargoes of classes 4.1, 4.2, 4.3, 5.1, 6.1, 8 or 9 for which no direct use is envisaged but which are carried for dumping, incineration or other methods of disposal. 10.2.2 Transboundary movement of waste means any shipment of wastes from an area under the national jurisdiction of one country to or through an area under the national jurisdiction of another country, or to or through an area not under the national jurisdiction of any country provided at least two countries are involved in the movement.

10.3 Applicability

10.3.1 The provisions of this section are applicable to the transport of wastes in bulk by ships and shall be considered in conjunction with all other provisions of this Code. 10.3.2 Solid cargoes containing or contaminated with radioactive materials shall be subject to the provisions applicable to the transport of radioactive materials and shall not be considered as wastes for the purposes of this section. *

10.4 Transboundary movements under the Basel Convention

Transboundary movement of wastes shall be permitted to commence only when: .1 notification has been sent by the competent authority of the country of origin, or by the generator or exporter through the channel of the competent authority of the country of origin, to the country of final destination; and .2 the competent authority of the country of origin, having received the written consent of the country of final destination stating that the wastes will be safely incinerated or treated by other methods of disposal, has given authorization for the movement.

10.5 Documentation

In addition to the required documentation for the transport of solid bulk cargoes, all transboundary movements of wastes shall be accompanied by a waste movement document from the point at * Basel Convention on the Control of Transboundary Movements of Hazardous Wastes and their Disposal (1989).

MSC 107/20/Add.2 Annex 9, page 44

which a transboundary movement commences to the point of disposal. This document shall be available at all times to the competent authorities and to all persons involved in the management of waste transport operations.

10.6 Classification of wastes

10.6.1 A waste containing only one constituent which is a cargo subject to the provisions of this Code applicable to cargoes of classes 4.1, 4.2, 4.3, 5.1, 6.1, 8 or 9 shall be regarded as being that particular cargo. If the concentration of the constituent is such that the waste continues to present a hazard inherent in the constituent itself, it shall be classified as the class applicable to that constituent.

10.6.2 A waste containing two or more constituents which are cargoes subject to the provisions of this Code applicable to cargoes of classes 4.1, 4.2, 4.3, 5.1, 6.1, 8 or 9 shall be classified under the applicable class in accordance with their dangerous characteristics and properties as described in 10.6.3 and 10.6.4.

10.6.3 The classification according to dangerous characteristics and properties shall be carried out as follows: .1 determination of the physical and chemical characteristics and physiological properties by measurement or calculation followed by classification according to the criteria applicable to the constituents; or .2 if the determination is not practicable, the waste shall be classified according to the constituent presenting the predominant hazard.

10.6.4 In determining the predominant hazard, the following criteria shall be taken into account: .1 if one or more constituents fall within a certain class and the waste presents a hazard inherent in these constituents, the waste shall be included in that class; or .2 if there are constituents falling under two or more classes, the classification of the waste shall take into account the order of precedence applicable to cargoes with multiple hazards set out in the IMDG Code.

10.7 Stowage and handling of wastes

Wastes shall be stowed and handled in accordance with the provisions of sections 1 to 9 of this Code and with any additional provisions included in the individual schedules for cargoes in group B applicable to the constituents presenting the hazards.

10.8 Segregation

Wastes shall be segregated in accordance with the provisions of 9.3.3 and 9.3.4, as appropriate.

10.9 Accident procedures

In the event that, during transport, a waste will constitute a danger for the carrying ship or the environment, the master shall immediately inform the competent authorities of the countries of origin and destination and receive advice on the action to be taken.

Section 11

Security provisions

Introductory note

The provisions of this section address the security of bulk cargoes in transport by sea. It should be borne in mind that some substances shipped as bulk cargo may, through their intrinsic nature, or when shipped in combination with other substances, be used as constituents for, or enhance the effect of, weapons used in the commission of unlawful acts. (It should also be borne in mind that ships used to carry bulk cargoes may also be used as a means to transport unauthorized weapons, incendiary devices or explosives, irrespective of the nature of the cargo carried.) National competent authorities may apply additional security provisions, which should be considered when offering or transporting bulk cargoes. The provisions of this section remain recommendatory except 11.1.1.

11.1 General provisions for companies, ships and port facilities

11.1.1 The relevant provisions of chapter XI-2 of SOLAS 74, as amended, and of part A of the ISPS Code shall apply to companies, ships and port facilities both engaged in the handling and transport of solid bulk cargoes and to which chapter XI-2 of SOLAS 74, as amended, applies, taking into account the guidance given in part B of the ISPS Code.

11.1.2 Due consideration should be given to the security-related provisions of the ILO/IMO Code of Practice on Security in Ports and the IMDG Code, as appropriate.

11.1.3 Any shore-based company personnel, ship-based personnel and port facility personnel engaged in the handling and transport of bulk cargoes should be aware of any security requirements for such cargoes, in addition to those specified in the ISPS Code, and commensurate with their responsibilities.

11.1.4 The training of the company security officer, shore-based company personnel having specific security duties, port facility security officer and port facility personnel having specific duties, engaged in the handling and transport of bulk cargoes, should also include elements of security awareness related to the nature of those cargoes, for example where such cargoes are materials hazardous only in bulk.

11.1.5 All shipboard personnel and port facility personnel who are not mentioned in 11.1.4 and are engaged in the transport of bulk cargoes should be familiar with the provisions of the relevant security plans related to those cargoes, commensurate with their responsibilities.

11.2 General provisions for shore-side personnel

11.2.1 For the purpose of this subsection, shore-side personnel covers individuals such as those who: – prepare transport documents for bulk cargoes;

– offer bulk cargoes for transport; – accept bulk cargoes for transport;

– handle bulk cargoes;

47

Bilaga

MSC 107/20/Add.2 Annex 9, page 46 – prepare bulk cargoes’ loading/stowage plans; – load/unload bulk cargoes into/from ships; and – enforce or survey or inspect for compliance with applicable rules and regulations; or – are otherwise involved in the handling and transport of bulk cargoes as determined by the competent authority. However, the provisions of 11.2 do not apply to: – the company security officer and appropriate shore-based personnel mentioned in section A/13.1 of the ISPS Code; – the ship security officer and the shipboard personnel mentioned in sections A/13.2 and A/13.3 of the ISPS Code; and – the port facility security officer, the appropriate port facility security personnel and the port facility personnel having specific security duties mentioned in sections A/18.1 and A/18.2 of the ISPS Code. For the training of those officers and personnel, refer to the ISPS Code. 11.2.2 Shore-side personnel engaged in transport by sea of bulk cargoes should consider security provisions for the transport of bulk cargoes commensurate with their responsibilities.

11.2.3 Security training

11.2.3.1 The training of shore-side personnel should also include elements of security awareness, the need to control access to cargoes and ships, and general guidance on the types of bulk cargoes of security significance. 11.2.3.2 Security awareness training should address the nature of security risks, recognizing security risks, methods to address and reduce risks and actions to be taken in the event of a security breach. It should include awareness of security plans (if appropriate, refer to 11.3), commensurate with the responsibilities of individuals and their part in implementing security plans. 11.2.3.3 Such training should be provided or verified upon employment in a position involving transport of bulk cargoes by sea and should be periodically supplemented with retraining. 11.2.3.4 Records of all security training undertaken should be kept by the employer and made available to the employee if requested.

11.3 Provisions for high-consequence solid bulk cargoes

11.3.1 For the purposes of this subsection, high-consequence solid bulk cargoes with high potential security implications are those which have the potential for misuse in an unlawful act and which may, as a result, produce serious consequences such as mass casualties or mass destruction, for example, class 5.1 ammonium nitrate UN 1942 and ammonium nitrate based fertilizers UN 2067. 11.3.2 The provisions of this subsection do not apply to ships and to port facilities (see the ISPS Code for ship security plan and for port security plan). 11.3.3 Consignors and others engaged in the transport of solid bulk cargoes with high potential security implications should adopt, implement and comply with a security plan that addresses at least the elements specified in 11.3.4. 11.3.4 The security plan should comprise at least the following elements: .1 specific allocation of responsibilities for security to competent and qualified persons with appropriate authority to carry out their responsibilities;

Hazard

Although this cargo passes the trough test (referred to in the UN Manual of Tests and Criteria, part III, section 39), and hence does not fall in class 9, when carried in bulk in large quantities, it may still be subject to decomposition if strongly heated from external sources. Once initiated, decomposition might gradually spread through the remainder of the cargo, producing large volumes of toxic gases. This cargo is not subject to an explosion hazard. Fertilizer dust might be irritating to skin and mucous membranes. It is a hygroscopic cargo and will cake if wet.

Stowage and segregation

“Separated from” sources of heat (see also Loading). Not to be stowed immediately adjacent to any tank, double bottom or pipe containing heated fuel oil, unless there are permanent means and procedures to monitor and control the temperature so that it does not exceed 50°C. Fertilizers of this type shall be stowed out of direct contact with a metal engine-room boundary. This may be done, for example, by using flame-retardant bags containing inert materials or by any equivalent arrangement approved by the competent authority of the country of origin. This requirement does not apply if the bulkhead is class A-60 or to short international voyages. The hatches of the cargo spaces, including those of ‘tween decks, shall be kept free at all times. In case of an emergency, whenever this material is on board, opening the hatches must be enabled (see 9.3.1.13 of this Code).

Hold cleanliness

Loading

Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code.

Prior to loading, the following provisions shall be complied with

In order to avoid heating up of the cargo, all electrical equipment or other equipment capable of developing heat, other than that of approved safe type, in the cargo spaces to be used for this cargo, shall be electrically disconnected from the power source, by appropriate means other than a fuse, at a point external to the space. This situation shall be maintained while the cargo is on board. Due consideration shall be given to the necessity to open hatches in case of decomposition to provide maximum ventilation, release pressure and heat, and slow down the reaction.

During loading, the following provisions shall be complied with

Organic contamination aggravates decomposition behaviour in the presence of sources of heat, and therefore bunkering of fuel oil shall not be allowed during loading. Pumping of fuel oil in spaces adjacent to the cargo spaces for this cargo, other than the engineroom, shall not be allowed.

Precautions

“NO SMOKING” signs shall be displayed on deck whenever this cargo is on board. Smoking shall not be allowed on deck and in the cargo spaces. No welding, burning, cutting or other operations involving the use of fire, open flame, spark or arc-producing equipment shall be carried out on equipment or structures in direct contact with the fertilizer.

The master and officers are to note that the ship’s fixed gas fire-fighting installation will be ineffective on decompositions involving this cargo and must not be used. If decomposition is identified, water must be applied without delay. Injection to the seat of decomposition is the first control measure because it uses less water and can be more effective in early decomposition stages. Total flooding is the final control measure but can introduce stability and stress issues. The consequential risk to the stability of the ship through fluidization of the cargo must be taken into account in both cases. Application of water to the surface of the cargo is much less effective and can give a false sense of safety. Appropriate precautions shall be taken to protect machinery and accommodation spaces from the dust of the cargo. Bilge wells of the cargo spaces shall be protected from ingress of the cargo. Due consideration shall be given to protect equipment from the dust of the cargo. Persons who may be exposed to the dust of the cargo shall wear goggles or other equivalent dust eye-protection and dust filter masks. Those persons shall wear protective clothing, as necessary.

Ventilation

The cargo spaces carrying this cargo shall not be ventilated during the voyage, except in an emergency.

Carriage

There shall be a daily monitoring, recording and assessment of the trends of the cargo temperature and oxygen concentration in the cargo space(s) throughout the voyage. Increase of temperature and decrease of oxygen concentration give an early indication of a decomposition. In addition, should decomposition occur, the residue left after decomposition may have only half the mass of the original cargo. Due consideration shall be given to the effect of the loss of mass on the stability of the ship.

As a minimum, the cargo’s contract specifications for moisture content, sulphur content and size shall be stated. 2 This cargo shall be stored for 7 days prior to loading. This substantially reduces the risk of spontaneous combustion in subsequent transport, storage and handling. 3 Before loading this cargo, the master shall ensure the following: .1 weather deck enclosures to the cargo space have been inspected to ensure their integrity. Such closures are closed and sealed; .2 all electrical cables and components situated in cargo spaces and adjacent enclosed spaces are free from defects. Such cables and electrical components are safe to be used in a flammable and/or dusty atmosphere or positively isolated. The provisions of this clause need not apply to engine-rooms where the engine-room is separated from the cargo space by a gastight bulkhead with no direct access. 4 Smoking and the use of naked flames shall not be permitted in the cargo areas and adjacent spaces and appropriate warning notices shall be posted in conspicuous places. Burning, cutting, chipping, welding or other sources of ignition shall not be permitted in the vicinity of cargo spaces or in other adjacent spaces. 5 This cargo shall not be dropped more than one metre during loading, to minimize the production of dust and fines. 6 Individual cargo spaces shall be loaded without interruption, where possible. Hot spots may develop in a cargo space that has been kept open for more than 6 days (or less in weather over 30°C). 7 Prior to departure, the master shall be satisfied that the surface of the material has been trimmed reasonably level to the boundaries of the cargo space to avoid the formation of gas pockets and to prevent air from permeating the body of the briquettes. Casing leading into the cargo space shall be adequately sealed. The shipper shall ensure that the master receives the necessary cooperation from the loading terminal. 8 Individual cargo spaces shall be closed and sealed as soon as practicable after the cargo has been loaded into each cargo space.

Precautions

1 The ship shall be suitably fitted and carry on board appropriate instruments for measuring the following without requiring entry into the cargo space: .1 concentration of methane in the atmosphere above the cargo; .2 concentration of oxygen in the atmosphere above the cargo; .3 concentration of carbon monoxide in the atmosphere above the cargo; .4 pH value of cargo hold bilge samples. These instruments shall be regularly serviced and calibrated. Ship personnel shall be trained in the use of such instruments. Details of gas measurement procedures are given at the end of this appendix.

* Refer to Interpretation of stowage and segregation requirements for brown coal briquettes and coal related to “hot areas” in the IMSBC Code (MSC.1/Circ.1351).

2 It is recommended that means be provided for monitoring the temperature of the cargo in the range of 0°C to 100°C to enable the measurement of temperature of the cargo during the voyage without requiring entry into the cargo space.

Carriage

1 As far as practicable, any gases which may be emitted from the cargo shall not be allowed to accumulate in adjacent enclosed spaces, such as store-rooms, carpenter’s shop, passageways, tunnels, etc. Such spaces shall be adequately ventilated and regularly monitored for methane, oxygen and carbon monoxide. 2 Under no circumstances, except in emergency, shall the hatches be opened or the cargo space be ventilated or entered during the voyage. 3 The atmosphere in the space above the cargo in each cargo space shall be regularly monitored for the concentrations of methane, oxygen and carbon monoxide. 4 The frequency of the monitoring shall be determined based upon the information provided by the shipper and the information obtained through the analysis of the atmosphere in the cargo space. The monitoring shall be conducted at least daily and as close as practical to the same time of day. The results of monitoring shall be recorded. The shipper may request more frequent monitoring, particularly if there is evidence of significant self-heating during the voyage. 5 The following issues shall be taken into account: .1 The oxygen level in the sealed cargo space will fall from an initial 21% over a period of days to stabilize at levels of the order of 6 to 15%. If the oxygen level does not fall below 20%, or rapidly increases after an initial fall, it is possible that the cargo space is inadequately sealed and is at risk of spontaneous combustion. .2 Carbon monoxide levels will build up to concentrations which fluctuate in the 200 to 2,000 parts per million (ppm) range in a safe, well-sealed cargo space. A rapid increase of approximately 1,000 ppm in carbon monoxide levels in this cargo over a 24-hour period is a possible indicator of spontaneous combustion, particularly if accompanied by an increase in methane levels. .3 The methane composition in briquette cargo is normally low, less than 5 ppm, and does not constitute a hazard. However, a sudden and continuing rise in methane levels, to concentrations above 10 ppm, is an indicator of the occurrence of spontaneous combustion in the hold. .4 The temperature in this cargo in a well-sealed cargo space normally remains at 5 to 10°C above seawater temperature, the increase being due to normal diurnal breathing of small quantities of air into the cargo space. Checking of the cargo space seals to minimize air leakage is essential. A rapid increase in temperature of approximately 20°C over 24 hours is evidence of spontaneous combustion. 6 Regular hold bilge testing shall be systematically carried out. If the pH monitoring indicates that a corrosion risk exists, the master shall ensure that all bilges are kept dry during the voyage in order to avoid possible accumulation of acids on tank tops and in the bilge system. 7 When the behaviour of the cargo during the voyage differs from that specified in the cargo information, the master shall report such differences to the shipper. Such reports will enable the shipper to maintain records on the behaviour of this cargo, so that the information being provided to the master can be reviewed in the light of the transport experience.

BROWN COAL BRIQUETTES (appendix, continued)

8 When the master is concerned that the cargo is showing any signs of self-heating or spontaneous combustion, such as an increase in the concentration of methane or carbon monoxide or an increase in temperature, as described above, the following actions shall be taken: * .1 Consult with the ship’s agent at the loading port. The company’s designated person ashore shall be advised immediately. .2 Check the seal of the cargo space and re-seal the cargo space, as necessary.

.3 Do not enter the cargo space and do not open the hatches, unless the master considers access is necessary for the safety of the ship or safety of life. When any ship’s personnel have entered into a cargo space, re-seal the cargo space immediately after the personnel vacate the cargo space.

.4 Increase the frequency of monitoring the gas composition, and temperature when practicable, of the cargo. .5 Send the following information, as soon as possible, to the ship’s owner or agent at the loading port to obtain expert advice: .1 the number of cargo spaces involved; .2 monitoring results of the carbon monoxide, methane and oxygen concentrations; .3 if available, temperature of the cargo, location and method used to obtain results; .4 the time the gas analyses were taken (monitoring routine); .5 the quantity of the cargo in the cargo space(s) involved; .6 the description of the cargo as per the shipper’s declaration, and any special precautions indicated on the declaration; .7 the date of loading, and estimated time of arrival (ETA) at the intended discharge port (which shall be specified); and .8 any other comments or observations the master may consider relevant.

Discharge

Prior to, and during, discharge: 1 The cargo space shall be kept closed until just before the commencement of discharge of that space. The cargo may be sprayed with a fine water spray to reduce dust. 2 Personnel shall not enter the cargo space without having tested the atmosphere above the cargo. The personnel entering into a cargo space in which the atmosphere contains oxygen levels below 21% shall wear self-contained breathing apparatus.† Carbon dioxide and carbon monoxide gas levels shall also be tested prior to entry into the cargo spaces. The recommended threshold limit value (TLV) for carbon monoxide is 50 ppm. 3 During discharge, attention shall be given to the cargo for signs of hot spots (i.e. steaming). If a hot spot is detected, the area shall be sprayed with fine water spray and the hot spot shall be removed immediately to prevent spreading. The hot spot cargo shall be spread out on the wharf away from the remainder of the cargo. 4 Prior to suspending the discharge of this cargo for more than 8 hours, the hatch covers and all other ventilation for the cargo space shall be closed.

* Refer to SOLAS regulation IX/1.2. † Refer to Revised recommendations for entering enclosed spaces aboard ships (resolution A.1050(27)).

BROWN COAL BRIQUETTES (appendix, continued)

Procedures for gas monitoring of brown coal briquette cargoes

1 Observations

1.1 Carbon monoxide monitoring, when conducted in accordance with the following procedures, will provide a reliable early indication of self-heating within this cargo. This allows preventive action to be considered without delay. A sudden rapid rise in carbon monoxide detected within a cargo space, particularly if accompanied by an increase in methane levels, is a conclusive indication that self-heating is taking place. 1.2 All vessels engaged in the carriage of this cargo shall carry on board an instrument for measuring methane, oxygen and carbon monoxide gas concentrations, to enable the monitoring of the atmosphere within the cargo space. This instrument shall be regularly serviced and calibrated in accordance with the manufacturer’s instructions. Care shall be exercised in interpreting methane measurements carried out in the low oxygen concentrations often found in unventilated cargo holds. The catalytic sensors normally used for the detection of methane rely on the presence of sufficient oxygen for accurate measurement. This phenomenon does not affect the measurement of carbon monoxide, or measurement of methane by infrared sensor. Further guidance may be obtained from the instrument manufacturer.

2 Sampling and measurement procedure

2.1 Equipment

2.1.1 An instrument which is capable of measuring methane, oxygen and carbon monoxide concentrations shall be provided on board a ship carrying this cargo. The instrument shall be fitted with an aspirator, flexible connection and a length of spark-proof metal tubing to enable a representative sample to be obtained from within the square of the hatch. 2.1.2 When recommended by the manufacturer, a suitable filter shall be used to protect the instrument against the ingress of moisture. The presence of even a small amount of water will compromise the accuracy of the measurement.

2.2 Siting of sampling points

2.2.1 In order to obtain meaningful information about the behaviour of this cargo in a cargo space, gas measurements shall be made via one sample point per cargo space. To ensure flexibility of measurement in adverse weather, however, two sample points shall be provided per cargo space, one on the port side and one on the starboard side of the hatch cover or hatch coaming (refer to the diagram of gas sampling point). Measurement from either of these locations is satisfactory. 2.2.2 Each sample point shall comprise a hole of diameter approximately 12 mm positioned as near to the top of the hatch coaming as possible. It shall be sealed with a sealing cap to prevent ingress of water and air. It is essential this cap be securely replaced after each measurement to maintain a tight seal. 2.2.3 The provision of any sample point shall not compromise the seaworthiness of the vessel.

2.3 Measurement

The explanation on procedures for measurement is as follows: .1 remove the sealing cap, insert the rigid tube into the sampling point and tighten the integral cap to ensure an adequate seal; .2 connect the instrument to the sampling tube; .3 draw a sample of the atmosphere through the tube, using the aspirator, until steady readings are obtained;

122

COAL (appendix)

Appendix

COAL

Properties and characteristics

1 Coals may emit methane, a flammable gas. A methane/air mixture containing between 5% and 16% methane constitutes an explosive atmosphere which can be ignited by sparks or naked flame, e.g. electrical or frictional sparks, a match or lighted cigarette. Methane is lighter than air and may, therefore, accumulate in the upper region of the cargo space or other enclosed spaces. If the cargo space boundaries are not tight, methane can seep through into spaces adjacent to the cargo space. 2 Coals may be subject to oxidation, leading to depletion of oxygen and an increase in carbon dioxide or carbon monoxide concentrations in the cargo space. Carbon monoxide is an odourless gas, slightly lighter than air and has flammable limits in air of 12% to 75% by volume. It is toxic by inhalation, with an affinity for blood haemoglobin over 200 times that of oxygen. 3 Some coals may heat spontaneously and the spontaneous heating may lead to spontaneous combustion in the cargo space. Flammable and toxic gases, including carbon monoxide, may be produced. 4 Some coals may be liable to react with water and produce acids which may cause corrosion. Flammable and toxic gases, including hydrogen, may be produced. Hydrogen is an odourless gas, much lighter than air, and has flammable limits in air of 4% to 75% by volume.

Segregation and stowage requirements

1 Unless expressly provided otherwise, boundaries of cargo spaces where this cargo is carried shall be resistant to fire and liquids. 2 This cargo shall be “separated from” goods of classes 1 (division 1.4), 2, 3, 4 and 5 in packaged form (see IMDG Code) and “separated from” solid bulk materials of classes 4 and 5.1. 3 Stowage of goods of class 5.1 in packaged form or solid bulk materials of class 5.1 above or below this cargo shall be prohibited. * 4 The master shall ensure that this cargo is not stowed adjacent to hot areas. 5 This cargo shall be “separated longitudinally by an intervening complete compartment or hold from” goods of class 1 other than division 1.4. Note: For interpretation of these terms, see section 9.

General requirements for all types of these cargoes

1 Prior to loading, the shipper or their appointed agent shall provide in writing to the master the characteristics of the cargo and the recommended safe handling procedures for loading and transport of the cargo. As a minimum, the cargo’s contract specifications for moisture content, sulphur content and size shall be stated, and especially whether the cargo may be liable to emit methane or self-heat.

* Refer to Interpretation of stowage and segregation requirements for brown coal briquettes and coal related to “hot areas” in the IMSBC Code (MSC.1/Circ.1351).

COAL (appendix, continued)

2 Before loading, the master shall ensure the following: .1 all cargo spaces and bilge wells are clean and dry. Any residue of waste material or previous cargo is removed, including removable cargo battens; and .2 all electrical cables and components situated in cargo spaces and adjacent enclosed spaces are free from defects. Such cables and electrical components are safe for use in an explosive atmosphere or positively isolated. The provisions of this clause need not apply to engine-rooms where the engine-room is separated from the cargo space by a gastight bulkhead with no direct access. 3 The ship shall be suitably fitted and carry on board appropriate instruments for measuring the following without requiring entry in the cargo space: .1 concentration of methane in the atmosphere; .2 concentration of oxygen in the atmosphere; .3 concentration of carbon monoxide in the atmosphere; and .4 pH value of cargo space bilge samples. 4 These instruments shall be regularly serviced and calibrated. Ship personnel shall be trained in the use of such instruments. Details of gas measurement procedures are given at the end of this appendix. 5 It is recommended that means be provided for measuring the temperature of the cargo in the range 0°C to 100°C to enable the measurement of temperature of the cargo while being loaded and during the voyage without requiring entry into the cargo space. 6 Smoking and the use of naked flames shall not be permitted in the cargo areas and adjacent spaces and appropriate warning notices shall be posted in conspicuous places. Burning, cutting, chipping, welding or other sources of ignition shall not be permitted in the vicinity of cargo spaces or in other adjacent spaces, unless the space has been properly ventilated and the methane gas measurements indicate it is safe to do so. 7 Prior to departure, the master shall be satisfied that the surface of the material has been trimmed reasonably level to the boundaries of the cargo space to avoid the formation of gas pockets and to prevent air from permeating the body of the briquettes. Casings leading into the cargo space shall be adequately sealed. The shipper shall ensure that the master receives the necessary cooperation from the loading terminal. 8 The atmosphere in the space above the cargo in each space shall be regularly monitored for the concentration of methane, oxygen and carbon monoxide. Details of gas monitoring procedures are given at the end of this appendix. The results of monitoring shall be recorded. The frequency of the monitoring shall be determined based upon the information provided by the shipper and the information obtained through the analysis of the atmosphere in the cargo space. 9 Unless expressly provided otherwise, surface ventilation shall be conducted in all cargo spaces carrying this cargo for the first 24 hours after departure from the loading port. During this period, the atmosphere in the cargo spaces shall be monitored once from one sample point per cargo space and, for the purpose of the gas monitoring, the ventilation shall be stopped for an appropriate period prior to the gas monitoring. 10 When the methane concentrations monitored within 24 hours after departure are at an acceptably low level, the ventilation openings shall be closed and the atmosphere in the cargo spaces shall be monitored. When the methane concentrations monitored within 24 hours after departure are not at an acceptably low level, surface ventilation shall be maintained, except for an appropriate period for gas monitoring, and the atmosphere in the cargo spaces shall be monitored. This procedure shall be followed until the methane concentrations become acceptably low level. In any event, the atmosphere in the cargo spaces shall be monitored on a daily basis.

Bilaga

MSC 107/20/Add.2 Annex 9, page 153

COAL (appendix, continued)

11 When significant concentrations of methane are subsequently observed in unventilated cargo spaces, the appropriate special precautions for coals emitting methane shall apply. 12 The master shall ensure, as far as practicable, that any gases which may be emitted from this cargo do not accumulate in adjacent enclosed spaces. 13 The master shall ensure that enclosed working spaces such as storerooms, carpenter’s shop, passageways, tunnels, etc., are regularly monitored for the presence of methane, oxygen and carbon monoxide. Such spaces shall be adequately ventilated. 14 Regular hold bilge testing shall be systematically carried out during the voyage carrying this cargo. If the pH monitoring indicates that a corrosion risk exists, bilges shall be frequently pumped out during the voyage in order to avoid possible accumulation of acids on tank tops and in the bilge system. 15 If the behaviour of the cargo during the voyage differs from that specified in the cargo declaration, the master shall report such differences to the shipper. Such reports will enable the shipper to maintain records on the behaviour of the coal cargoes, so that the information provided to the master can be reviewed in the light of transport experience.

Special precautions

1 Coals emitting methane

When the shipper has informed that the cargo is liable to emit methane or analysis of the atmosphere in the cargo space indicates the presence of methane in excess of 20% of the Lower Explosion Limit (LEL), the following additional precautions shall be taken: .1 Adequate surface ventilation shall be maintained, except for an appropriate period for the purpose of gas monitoring. .2 Care shall be taken to remove any accumulated gases prior to operation of the hatch covers or other openings for any reason, including discharging. Care shall be taken to operate hatch covers of the cargo spaces and other openings to avoid creating sparks. Smoking and the use of naked flame shall be prohibited. .3 Personnel shall not be permitted to enter the cargo space or enclosed adjacent spaces unless the space has been ventilated and the atmosphere tested and found to be gas-free and to have sufficient oxygen to support life. Notwithstanding these provisions, emergency entry into the cargo space may be permitted without ventilation, testing the atmosphere or both, provided that the entry into the cargo space is undertaken only by trained personnel wearing self-contained breathing apparatus under the supervision of a responsible officer and special precautions are observed to ensure that no source of ignition is carried into the space. .4 The master shall ensure that enclosed working spaces such as storerooms, carpenter’s shops, passageways, tunnels, etc., are regularly monitored for the presence of methane. Such spaces shall be adequately ventilated and, in the case of mechanical ventilation, only equipment safe for use in an explosive atmosphere shall be used.

2 Self-heating coals

When the shipper informed that the cargo is likely to self-heat or analysis of the atmosphere in the cargo space indicates an increasing concentration of carbon monoxide, then the following additional precautions shall be taken: .1 The cargo spaces shall be closed immediately after completion of loading in each cargo space. The hatch covers may also be additionally sealed with a suitable sealing tape. Only natural surface ventilation shall be permitted and ventilation shall be limited to the absolute minimum time necessary to remove methane which may have accumulated.

COAL (appendix, continued)

.2 Personnel shall not enter the cargo space during the voyage, unless they are wearing self-contained breathing apparatus and access is critical to safety of life and the safety of the ship. .3 Prior to loading, temperature of this cargo shall be monitored. This cargo shall only be accepted for loading when the temperature of the cargo is not higher than 55°C. .4 When the carbon monoxide level is increasing steadily, a potential self-heating may be developing. In such a case, the cargo space shall be completely closed and all ventilation ceased, and the master shall seek expert advice immediately. Water shall not be used for cooling material or fighting coal cargo fires at sea, but may be used for cooling the boundaries of the cargo space. .5 When the carbon monoxide level in any cargo space reaches 50 ppm or exhibits a steady rise over three consecutive days, a self-heating condition may be developing and the master shall * inform the shipper and the company of, at least, the following information if an accurate assessment of the situation is to be achieved: .1 identity of the cargo spaces involved; monitoring results covering carbon monoxide, methane and oxygen concentrations; .2 if available, temperature of the cargo, location and method used to obtain results; .3 time gas sample taken (monitoring routine); .4 time ventilators opened/closed; .5 quantity of coal in hold(s) involved; .6 type of coal as per cargo information, and any special precautions indicated on information; .7 date loaded, and ETA at intended discharge port (which shall be specified); and .8 comments or observations from the ship’s master.

3 Gravity-fed self-unloading bulk carrier

3.1 A gravity-fed self-unloading bulk carrier means a vessel that has gravity-fed systems from the bottom of cargo holds, using gates that may be opened or closed to feed the cargo onto conveyor belts. Such belts run in a fore and aft direction underneath the holds; from there the cargo is carried by means of conveyor systems to the deck and discharged onto shore with a self-unloading boom that can extend over the shore and has a conveyor belt. This is not applicable for the vessels with unloading systems such as cranes and grabs. 3.2 When this cargo is carried on a gravity-fed self-unloading bulk carrier, the following requirements of this appendix need not apply: – paragraph 1 of “Segregation and stowage requirements”; and – paragraph 9 of “General requirements for all types of these cargoes”. 3.3 Loaded voyage procedures for atmospheric monitoring of cargoes 3.3.1 Bulk coal cargo safety procedures 3.3.1.1 These requirements apply when these cargoes are to be carried on a gravity-fed self-unloading bulk carrier. It is recommended that a document, such as a flow chart, describing cargo operations and carriage procedures for these cargoes be provided to the ship by the vessel’s operator. 3.4 Ventilation 3.4.1 When ventilating, it shall be ensured that excess air does not ingress excessively into the body of the cargo of coal as this may eventually promote self-heating.

* Refer to SOLAS regulation IX/1.2.

COAL (appendix, continued)

3.4.2 Due to the presence of non-airtight unloading gates at the bottom of the cargo hoppers just above the tunnels, the following methods of ventilation shall be used: – if methane is detected in the tunnel, it shall be “positive-pressure” ventilated (more supply than exhaust in the tunnels, to remove methane gas); and – if carbon monoxide is detected in the tunnel, it shall be “negative-pressure” ventilated (more exhaust than supply in the tunnels, to remove carbon monoxide). The release of carbon monoxide may be an indication of self-heating.

Procedures for gas monitoring of coal cargoes

1 Observations

1.1 Carbon monoxide monitoring, when conducted in accordance with the following procedures, will provide a reliable early indication of self-heating within this cargo. This allows preventive action to be considered without delay. A steady rise in the level of carbon monoxide detected within a cargo space is a conclusive indication that self-heating is taking place. 1.2 All vessels engaged in the carriage of this cargo shall carry on board an instrument for measuring methane, oxygen and carbon monoxide gas concentrations, to enable the monitoring of the atmosphere within the cargo space. This instrument shall be regularly serviced and calibrated in accordance with the manufacturer’s instructions. Care shall be exercised in interpreting methane measurements carried out in the low oxygen concentrations often found in unventilated cargo holds. The catalytic sensors normally used for the detection of methane rely on the presence of sufficient oxygen for accurate measurement. This phenomenon does not affect the measurement of carbon monoxide, or measurement of methane by infrared sensor. Further guidance may be obtained from the instrument manufacturer.

2 Sampling and measurement procedure

2.1 Equipment 2.1.1 An instrument which is capable of measuring methane, oxygen and carbon monoxide concentrations shall be provided on board a ship carrying this cargo. The instrument shall be fitted with an aspirator, flexible connection and a length of spark-proof metal tubing to enable a representative sample to be obtained from within the square of the hatch. 2.1.2 When recommended by the manufacturer, a suitable filter shall be used to protect the instrument against the ingress of moisture. The presence of even a small amount of moisture will compromise the accuracy of the measurement.

2.2 Siting of sampling points 2.2.1 In order to obtain meaningful information about the behaviour of this cargo in a cargo space, gas measurements shall be made via one sample point per cargo space. To ensure flexibility of measurement in adverse weather, two sample points shall be provided per cargo space, one on the port side and one on the starboard side of the hatch cover or hatch coaming. (Refer to the diagram of gas sampling point.) Measurement from either of these locations is satisfactory.

2.2.2 Each sample point shall comprise a hole of diameter approximately 12 mm positioned as near to the top of the hatch coaming as possible. It shall be sealed with a sealing cap to prevent ingress of water and air. It is essential that this cap is securely replaced after each measurement to maintain a tight seal. 2.2.3 The provisions of any sample point shall not compromise the seaworthiness of the vessel.

2.3 Measurement 2.3.1 The explanation on procedures for measurement is as follows: .1 remove the sealing cap, insert the spark-proof metal tube into the sampling point and tighten the collar to ensure an adequate seal; .2 connect the instrument to the sampling tube; .3 draw a sample of the atmosphere through the tube, using the aspirator, until steady readings are obtained; .4 log the results on a form which records cargo space, date and time for each measurement; and .5 put back the sealing cap.

2.4 Measurement strategy The identification of incipient self-heating from measurement of gas concentrations is more readily achieved under unventilated conditions. This is not always desirable because of the possibility of the accumulation of methane to dangerous concentrations. This is primarily, but not exclusively, a problem in the early stages of a voyage. Therefore it is recommended that cargo spaces are initially ventilated until measured methane concentrations are at an acceptably low level.

2.5 Measurement in unventilated holds Under normal conditions, one measurement per day is sufficient as a precautionary measure. However, if carbon monoxide levels are higher than 30 ppm then the frequency shall be increased to at least twice a day at suitably spaced intervals. Any additional results shall be logged.

2.6 Measurement in ventilated holds 2.6.1 If the presence of methane is such that the ventilators are required to remain open, then a different procedure shall be applied to enable the onset of any incipient self-heating to be detected. 2.6.2 To obtain meaningful data the ventilators shall be closed for a period before the measurements are taken. This period may be chosen to suit the operational requirements of the vessel, but it is recommended that it is not less than 4 hours. It is vital in the interests of data interpretation that the shutdown time is constant whichever time period is selected. These measurements shall be taken on a daily basis.

2.7 Measurement in cargo and self-unloading spaces of gravity-fed self-unloading

bulk carrier

2.7.1 Measurement in unventilated cargo and self-unloading spaces 2.7.1.1 When the shipper has declared that the coal cargo has or may have self-heating characteristics, the holds shall not be ventilated unless otherwise specified in this section.

2.7.1.2 Under normal conditions, one measurement per day is sufficient as a precautionary measure. If carbon monoxide levels are higher than 30 ppm then the frequency of measurements shall be increased to at least twice daily, at suitable intervals. Any additional results shall be logged. 2.7.1.3 If the carbon monoxide level in any hold indicates a steady rise or reaches 50 ppm, a self-heating condition may be developing and the owners of the vessel shall be notified as outlined in the procedures. Above this level, the vessel shall operate on “negative-pressure” ventilation, in order to reduce the amount of carbon monoxide. Regular monitoring of carbon monoxide levels shall continue. 2.7.1.4 Persons entering cargo or unloading spaces with carbon monoxide levels higher than 30 ppm shall not do so without self-contained breathing apparatus.*

2.7.2 Measurement in ventilated cargo and self-unloading spaces 2.7.2.1 If the presence of methane is indicated by monitor, and such that ventilation is required, then a different procedure shall be applied to enable the onset of any possible self-heating to be detected. “Positive-pressure” or “through ventilation” shall be operated to remove the methane.

* Refer to Revised recommendations for entering enclosed spaces aboard ships (resolution A.1050(27)).

2.7.2.2 To obtain meaningful data, the ventilators and/or ventilation shall be closed for a period before measurements are taken. This period may be chosen to suit the operational requirements of the vessel, but it is recommended that it is not less than 4 hours. It is vital, in the interests of data interpretation, that the shutdown time is constant whichever time period is selected. These measurements shall be taken on a daily basis. If the carbon monoxide results exhibit a steady rise, or exceed 50 ppm on any day, the owner shall be notified. 2.7.2.3 In addition, the following points shall be considered: – at no time shall ventilation be shut down when crew members are in the self-unloading spaces; – special fire-fighting equipment and/or procedures may be necessary for the vessel; and – establish specific crew training for gravity-fed self-unloading bulk carriers.

Briquettes, hot-moulded (continued)

Weather precautions

This cargo shall be kept as dry as practicable during loading and the voyage. Open storage is acceptable prior to loading. This cargo shall not be loaded onto ships or transferred between ships or barges during precipitation. During loading of this cargo, all non-working hatches of the cargo spaces into which this cargo is loaded, or to be loaded, shall be kept closed. Only when weather permits may non-working hatch covers be left open for a minimum of 1 hour after completion of each pour, to allow cooling after cargo handling in bulk.

Loading

Prior to loading this cargo, the shipper shall provide the master with a certificate issued by a competent person recognized by the competent authority of the port of loading stating that the cargo, at the time of loading, is suitable for shipment and that it conforms with the requirements of this Code; that the quantity of fines and small particles (under 6.35 mm in size) does not exceed more than 5% by weight; the moisture content does not exceed 1.0% and the temperature does not exceed 65°C. This cargo shall not be loaded when the temperature is in excess of 65°C, if its moisture content is in excess of 1.0% or if the quantity of fines and small particles (under 6.35 mm in size) exceeds 5% by weight. Appropriate precautions shall be taken during loading in order to have a cargo composed of essentially whole briquettes. The cargo shall be loaded in such a way so as to minimize breakage of briquettes and the additional generation of fines and small particles (under 6.35 mm in size) and concentration of fines in any area of the cargo. The addition of fines and particles under 6.35 mm in size or dust in homogenous cargoes of briquettes shall be prohibited. Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code. Due consideration shall be given to evenly spreading the cargo across the tank top to minimize the concentration of fines. The cargo temperature shall be monitored during loading and recorded in a log detailing the temperature for each lot of cargo loaded, a copy of which shall be provided to the master. After loading, a certificate, confirming that throughout the whole consignment the fines and small particles (under 6.35 mm in size) do not exceed 5% by weight, shall be issued by a competent person recognized by the competent authority of the port of loading. As the density of the cargo is extremely high, the tank top may be overstressed unless the cargo is evenly spread across the tank top to equalize the weight distribution. Due consideration shall be given to ensure that the tank top is not overstressed during the voyage and during loading by a pile of the cargo.

Precautions

The carrier’s nominated technical persons or other representatives shall have reasonable access to stockpiles and loading installations for inspection. Shippers shall provide comprehensive information on the cargo and safety procedures to be followed in the event of emergency.

Not applicable Not applicable SH and/or WF B

Hazard

Temporary increase in temperature of about 30°C due to self-heating may be expected after material handling in bulk. There is a risk of overheating, fire and explosion during transport. This cargo reacts with air and with fresh water or seawater to produce heat and hydrogen. Hydrogen is a flammable gas that can form an explosive mixture when mixed with air in concentrations above 4% by volume. The reactivity of this cargo depends upon the origin of the ore, the process and temperature of reduction, and the subsequent ageing procedures. Cargo heating may generate very high temperatures that are sufficient to ignite the cargo. Build-up of fines may also lead to self-heating, auto-ignition and explosion. Oxygen in cargo spaces and enclosed spaces may be depleted.

Stowage and segregation

“Separated from” goods of classes 1 (division 1.4S), 2, 3, 4 and 5, and class 8 acids in packaged form (See IMDG Code). “Separated from” solid bulk materials of classes 4 and 5.

The reactivity of this cargo is extremely difficult to assess due to the nature of the material that can be included in the category. A worst case scenario should therefore be assumed at all times.

Stowage and segregation

“Separated from” goods of classes 1 (division 1.4S), 2, 3, 4 and 5, and class 8 acids in packaged form (see IMDG Code). “Separated from” solid bulk materials of classes 4 and 5. Goods of class 1, other than division 1.4S, shall not be carried in the same ship. Boundaries of compartments where this cargo is carried shall be resistant to fire and passage of liquid.

Hold cleanliness

Cargo spaces shall be clean, dry and free of salt and residues of previous cargoes. Prior to loading, wooden fixtures such as battens, loose dunnage, debris and combustible materials shall be removed.

Weather precautions

The cargo shall be kept within the permissible moisture content indicated in this schedule at all times during loading, and during transportation. This cargo shall not be loaded onto ships, or transferred between ships or barges, during ANY precipitation. During loading of this cargo, all non-working hatches of cargo spaces into which this cargo is loaded, or is to be loaded, shall be kept closed.

Loading

Prior to loading, the terminal shall ensure that the conveyor belts and all other equipment used for loading this cargo contain no accumulation of water or other substances. Each time cargo operations are commenced or restarted, particularly after rain or washing down, any loading belt shall be operated empty and not over a ship’s cargo space. Prior to loading, an ultrasonic test or another equivalent method with a suitable instrument shall be conducted to ensure weathertightness of the hatch covers and closing arrangements and all readings shall confirm weathertightness. Prior to loading this cargo, the shipper shall provide the master with a certificate issued by a competent person recognized by the competent authority of the port of loading stating that the cargo, at the time of loading, is suitable for shipment; that it conforms with the requirements of this Code; that the moisture content does not exceed 0.3%; and the temperature does not exceed 65°C. This certificate shall state that the cargo meets the loading criteria with regard to ageing and material temperature. As the density of the cargo is extremely high, the tank top may be overstressed unless the cargo is evenly spread across the tank top to equalize the weight distribution. Due consideration shall be given to ensure that the tank top is not overstressed during the voyage and during loading by a pile of the cargo. The cargo shall not be accepted for loading when its temperature is in excess of 65°C or if its moisture content is in excess of 0.3%. Any cargo that has been wetted, or is known to have been wetted, shall not be loaded into any cargo space. Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code. The cargo temperature shall be monitored during loading and recorded in a log detailing the temperature for each lot of cargo loaded, a copy of which shall be provided to the master. After loading, a certificate shall be issued by a competent person recognized by the competent authority of the port of loading confirming that throughout the whole consignment of fines and small particles the moisture content has not exceeded 0.3% and the temperature does not exceed 65°C. On completion of loading of a cargo space it shall be immediately closed and sealed. Sufficient inert gas shall then be introduced to achieve an oxygen concentration less than 5% throughout the cargo space.

Precautions

Due consideration shall be given to the possibility of moisture inside the cargo pile in order to avoid loading of wet cargo or a wet part of the cargo, recognizing that the bottom of the pile can be wet even though the surface of cargo pile looks dry. The carrier’s nominated technical persons or other representatives shall have reasonable access to stockpiles and loading installations for inspection. Prior to shipment, the cargo shall be aged for at least 30 days and a certificate confirming this shall be issued by a competent person recognized by the competent authority of the port of loading. Shippers shall provide to the master, prior to loading, comprehensive information on the cargo and safety procedures to be followed in the event of emergency. This advice may be an amplification of this Code, but shall not be contrary thereto in respect of safety.

Where practicable, ballast tanks adjacent to the cargo spaces containing this cargo, other than double-bottom tanks, shall be kept empty. Weathertightness shall be maintained throughout the voyage. Bilge wells of the cargo spaces shall be clean, dry and protected from ingress of the cargo, using non-combustible material. The introduction of moisture and accumulation of condensation in the cargo spaces shall be avoided. Appropriate precautions shall be taken to protect equipment, machinery and accommodation spaces from the dust of the cargo. Radars and exposed radiocommunication equipment of ships which carry this cargo shall be protected from the dust of this cargo. Persons who may be exposed to the dust of the cargo shall wear protective clothing, goggles or other equivalent dust eye-protection and dust filter masks, as necessary. During any handling of this cargo, “NO SMOKING” signs shall be posted on decks and in areas adjacent to cargo spaces, and no naked light shall be permitted in these areas. Smoking, burning, cutting, chipping, grinding or other sources of ignition shall not be allowed in the vicinity of cargo spaces containing this cargo at any time. Cargo spaces containing this cargo and adjacent spaces may become oxygen-depleted. No person shall enter a loaded cargo space or an enclosed adjacent space unless the space has been ventilated * and the atmosphere tested and found to be gas-free and have sufficient oxygen to support life. Notwithstanding, emergency entry may be permitted without ventilation, testing, or both provided that the entry into the space is undertaken only by trained personnel wearing self-contained breathing apparatus under the supervision of a responsible officer and no source of ignition is introduced into the space. Prior to loading, provision shall be made to introduce a dry, inert gas at tank top level so that the inert gas purges the air from the cargo and fills the free volume above. Nitrogen is preferred for this purpose. All vents, accesses and other openings, such as coaming drains, that could allow the inert atmosphere to be lost from cargo spaces carrying this cargo shall be closed and sealed. The ship shall be provided with the means to ensure that a requirement of this Code to maintain the oxygen concentration below 5% can be achieved and maintained throughout the voyage. The ship’s fixed CO2 fire-fighting system shall not be used for this purpose. Consideration shall be given to providing the vessel with the means to top up the cargo spaces with additional supplies of inert gas, taking into account the duration of the voyage. The ship shall be provided with the means for reliably measuring the temperatures at several points within the stow and determining the concentrations of hydrogen and oxygen in the cargo space atmosphere on voyage. Appropriate precautions shall be taken to minimize, as far as practicable, the loss of the inert atmosphere. Any cargo that has already been loaded into a cargo space and which subsequently is exposed to additional fresh water or seawater over its natural moisture content and becomes wetted, or in which reactions have started and its temperature has exceeded 120°C, shall be discharged without delay. On completion of loading of a cargo space it shall be immediately closed and sealed. Sufficient inert gas shall then be introduced to achieve an oxygen concentration less than 5% throughout the cargo space. The ship shall not sail until the master and a competent person recognized by the competent authority of the port of loading are satisfied: .1 that all loaded cargo spaces are correctly sealed and inerted; .2 that the temperature of the cargo has stabilized at all measuring points and that the temperature does not exceed 65°C; and .3 that, at the end of the inerting process, the concentration of hydrogen in the free space of the holds has stabilized and does not exceed 0.2% by volume.

Ventilation

The cargo spaces carrying this cargo shall remain tightly sealed and the inert condition maintained during the voyage.

Carriage

For quantitative measurements of hydrogen and oxygen, suitable detectors shall be on board while this cargo is carried. The detectors shall be suitable for use in an oxygen-depleted atmosphere and of a type certified safe for use in explosive atmospheres. The concentrations of hydrogen and oxygen in the cargo spaces carrying this cargo shall be measured at regular intervals during the voyage, and the results of the measurements shall be recorded and kept on board for a minimum of two years.

The oxygen concentration in the cargo spaces carrying this cargo shall be maintained at less than 5% throughout the duration of the voyage by topping up with inert gas. Cargo temperatures shall be taken at regular intervals during the voyage and the results of the measurements shall be recorded and kept on board for a minimum of two years. If the temperature in the cargo space exceeds 65°C or the monitored hydrogen concentration exceeds 1% (> 25% lower explosive limit (LEL)) by volume, appropriate safety precautions shall be taken in accordance with the procedures provided by the shipper in the event of emergency. If in doubt, expert advice shall be sought. Bilge wells shall be checked regularly for the presence of water. If water is found, it shall be removed by pumping or draining the bilge wells. Consideration shall be given to increasing the frequency of cargo monitoring following periods of bad weather. All measurements shall be taken so as to minimize, as far as practicable, the loss of inert gas from the cargo spaces.

Discharge

The hydrogen concentration in the cargo space shall be measured immediately before any opening action of the hatch covers. If the hydrogen concentration is greater than 1% (> 25% lower explosive limit (LEL)) by volume, all appropriate safety precautions in conformity with the procedures provided by the shipper or the recommendations of the competent authority shall be taken. If in doubt, expert advice shall be sought. During precipitation, all cargo operations shall be suspended and holds containing cargo shall be closed. Monitoring for hydrogen of those holds containing cargo shall be resumed.

Clean-up

Accumulations of dust from this cargo on deck or in proximity to cargo spaces shall be removed as quickly as possible. Hosing with seawater shall be avoided. Consideration shall be given to carefully cleaning exposed radiocommunication equipment to which dust from the cargo might adhere, such as radar, radio aerials, VHF installations, AIS and GPS.

Fines and small particles with an average size less than 6.35 mm, particles Not applicable 1,850 to 3,300 0.30 to 0.54 larger than 12 mm not to exceed 3% by weight

Hazard classification

Subsidiary Class MHB Group hazard(s)

Not applicable Not applicable SH and/or WF A and B

Hazard

Temporary increase in temperature of about 30°C over ambient, due to oxidation and consequent self-heating, may be expected after material handling in bulk. There is a risk of overheating, fire and explosion during transport due to the fact that this cargo reacts with air, fresh water and seawater to produce hydrogen and heat. Hydrogen is a lighter than air, flammable gas, that can form an explosive atmosphere when mixed with air in concentrations above 4% by volume. Oxygen in cargo holds and in enclosed adjacent spaces may be depleted. Flammable gas may also build up in these spaces. This cargo may liquefy if shipped at a moisture content in excess of its transportable moisture limit (TML). See sections 7 and 8 of this Code.

Stowage and segregation

“Separated from” goods of classes 1 (division 1.4S), 2, 3, 4 and 5, and class 8 acids in packaged form (see the IMDG Code). “Separated from” solid bulk materials of classes 4 and 5. Goods of class 1, other than division 1.4S, shall not be carried in the same ship. Boundaries of compartments where this cargo is carried shall be resistant to fire and passage of liquid.

Hold cleanliness

The cargo spaces shall be clean, dry and free of salt and residues of previous cargoes. Prior to loading, wooden fixtures such as battens, loose dunnage, debris and combustible materials shall be removed.

(By-product fines with moisture content of at least 2%) (continued)

Weather precautions

Storage in the open air shall be permitted prior to loading, subject to any requirements of the competent authority of the port of loading. During storage, the material shall be piled such as to allow the greatest possible exposure to the atmosphere and thus facilitate its natural ageing. When a cargo is carried in a ship other than a ship complying with the requirements in 7.3.2 of this Code, the following provisions shall be complied with: .1 the moisture content of the cargo shall be kept less than its TML during loading operations and the voyage; .2 unless expressly provided otherwise in this individual schedule, the cargo shall not be handled during precipitation; .3 unless expressly provided otherwise in this individual schedule, during handling of the cargo, all non-working hatches of the cargo spaces into which the cargo is loaded, or to be loaded, shall be closed; and .4 the cargo in a cargo space may be discharged during precipitation provided that the total amount of the cargo in the cargo space is to be discharged in the port.

Loading

Prior to loading this cargo, the shipper shall provide the master with a certificate issued by a competent person recognized by the competent authority of the port of loading stating that the cargo does not meet the criteria for class 4.2 materials. As the density of the cargo is extremely high, the tank top may be overstressed unless the cargo is evenly spread across the tank top to equalize the weight distribution. Due consideration shall be given to ensure that the tank top is not overstressed during the voyage and during loading by a pile of the cargo. Prior to loading, the cargo shall be prepared and aged naturally for a minimum of 30 days. Prior to loading this cargo, the shipper shall provide the master of the ship with a certificate issued by a competent person recognized by the competent authority of the port of loading stating that the cargo has been prepared and aged naturally for a minimum of 30 days. Prior to loading, the temperature of the cargo in the stockpile to be loaded shall be measured by the shipper for three consecutive days and recorded in a log. Measurements shall be taken 20 to 30 cm below the surface and at 3-metre intervals over the length and width of the stockpile. The cargo shall not be loaded if its temperature is in excess of 65°C. Care shall be taken by all parties concerned to ensure that particles coarser than 6.35 mm are, as far as is practicable, evenly distributed throughout the entire cargo, in order to avoid build-up of concentrations of coarse material. Trim in accordance with the relevant provisions required under sections 4 and 5 of this Code. The cargo temperature shall be monitored during loading and recorded in a log detailing the temperature of each lot of cargo loaded, a copy of which shall be provided to the master. Hatch covers shall, weather permitting and subject to the absence of precipitation, remain open after completion of loading of the respective holds and placement of thermocouples, in order to allow cooling of the cargo, stabilization of cargo temperature and natural ventilation of the hold. Otherwise, hatches shall be closed and sealed immediately upon completion of loading and placement of thermocouples. Monitoring of temperature and hydrogen concentration shall then be commenced.

Bilaga

MSC 107/20/Add.2 Annex 9, page 199

DIRECT REDUCED IRON (D)

(By-product fines with moisture content of at least 2%) (continued)

On completion of loading, the ship shall wait for 24 hours (or longer as may be required) before sailing, in order to ensure that: .1 all loaded cargo holds are correctly closed and sealed; .2 the temperature of the cargo at all measuring points is stable and does not exceed 65°C for at least 12 consecutive hours; and .3 that the concentration of hydrogen in the head space of the holds has stabilized and does not exceed 1% by volume (25% of the lower explosive limit (LEL)) for at least 12 consecutive hours. If after loading and before sailing any cargo temperatures are found to be in excess of 65°C, the material so affected shall be allowed to cool naturally to 65°C or less, or be cooled by mechanical intervention prior to sailing, for example with a front end loader, subject always to proper monitoring and safety precautions being in place. Other measures may be specified by the competent authorities concerned. On completion of loading and before sailing, a certificate shall be issued by a competent person recognized by the competent authority of the port of loading, stating that: .1 the proportion of material larger than 12 mm is no more than 3% by weight; .2 the moisture content of the cargo loaded is at least 2% and below the TML; and .3 the temperature of the cargo loaded does not exceed 65°C.

Precautions

It is recommended that an experienced cargo technician appointed by the shipper be on board the ship during loading and throughout the voyage. Prior to loading, the shipper shall provide the master with comprehensive information on the risk of hydrogen evolution and the factors which may affect the rate thereof. Such risk assessment may include, but not be limited to: .1 expected weather conditions; .2 such information as is then available on the hydrogen evolution rate; .3 planned speed of the ship; .4 availability and accessibility of ports of refuge en route; and .5 distance to the port of discharge. It is strongly recommended that weather routing be utilized in the above-mentioned risk assessment. Prior to shipment, the master, with the aid of the shipper and/or the cargo technician if appointed, shall ensure that all concerned crew members have been informed about and understand the potential risks associated with the carriage of this cargo. Such knowledge exchange shall be recorded in the ship-shore safety checklist. The shipper shall ensure that expert advice is available at all times during the voyage and shall provide relevant contact details to the master prior to sailing. Any material that has become wetted, for example, due to precipitation, shall not be loaded unless such material has been rectified regarding its moisture content. In the event that a hold carrying this cargo has to be closed prior to completion, for example, due to precipitation, such hold shall be monitored for hydrogen concentration as frequently as required and ventilated to keep the hydrogen concentration less than 1% by volume (25% LEL). The ship’s cargo holds shall be provided with the means of reliably measuring the temperatures at several points within the stow and the concentrations of hydrogen and oxygen in the cargo hold atmosphere during the voyage without entering the cargo holds. Such measuring devices shall be suitable for use in an oxygen-depleted atmosphere and of a certified safe type for use in an explosive atmosphere.

Holds carrying this cargo and adjacent spaces may become oxygen-depleted. No person shall enter a loaded cargo space or enclosed adjacent space unless such space has been ventilated and the * atmosphere tested and found to be gas-free and to have sufficient oxygen to support life.

Ventilation

During the voyage, mechanical surface ventilation shall be provided in each cargo hold carrying this cargo, in order to keep the hydrogen concentration less than 1% by volume (25% LEL). The mechanical surface ventilation system shall be of a certified safe type for use in an explosive atmosphere, capable of ventilating the cargo surface, as stipulated in 3.5 of this Code. Suitable wire mesh guards shall be fitted over inlet and outlet ventilator openings. Mechanical surface ventilation shall be available at all times, either by compliance with the Load Line Convention, Annex I, regulation 19(3), or by adopting measures to avoid a situation whereby the cargo hold mechanical ventilation system could not be used due to rough seas, such measures to be in keeping with good seamanlike practices as for similar cargoes emitting intermittent combustible gases and advice from weather routing service providers. Ventilation shall be such as to provide surface ventilation and to avoid the possibility of the build-up of flammable gas/air mixtures. Ventilation other than surface ventilation shall not be applied and on no account shall air be directed into the body of the cargo. In order to minimize the possibility of the introduction of oxygen and moisture into the cargo holds, periods of surface ventilation shall be limited to the time necessary to remove hydrogen which may have accumulated in the cargo holds and maintain the hydrogen concentration below 1% by volume (25% LEL). 3 Mechanical ventilation shall be such as to enable an airflow of at least 1.2 m per hour per tonne of cargo in each hold carrying this cargo when needed, and in any case shall have an adequate capacity to ventilate down to a concentration of 0.2% hydrogen by volume (5% LEL) or less. Prior to loading, an inspection of the mechanical ventilation system shall be conducted to ensure that it is functioning properly. Two spare sets of ventilation equipment of a certified safe type for use in an explosive atmosphere shall be available on board the ship during the voyage. A crew member or other person with the ability to install the spare fans shall be available on board throughout the voyage. In addition, natural ventilation shall be provided in enclosed cargo holds intended for the carriage of this cargo. The operating period and frequency of the ventilation system shall be determined based on the measured hydrogen concentration and the indicated rate of increase/decrease thereof over time. It is therefore very important to establish a time-based gas prediction curve (see the appendix to this schedule). Such curve shall be first determined prior to sailing and, recognizing that conditions can change during the voyage, be updated from time to time during the voyage as may be appropriate, for example in the case of seawater intrusion into a hold carrying this cargo. Based on the time-based gas prediction curve(s), the risk assessment shall as soon as possible be updated accordingly, and the voyage plan shall be optimized to avoid a situation where the cargo hold mechanical ventilation system might not be able to be used due to rough seas for periods greater than the estimated time for the concentration of hydrogen to reach 1% by volume (25% LEL). The port authorities at planned ports of refuge shall be advised in advance and a confirmation that access would be granted shall be obtained prior to adding such port to the voyage plan. The risk assessment, voyage plan, and weather routing, if adopted, shall be updated as frequently during the voyage as updates on the weather become available, as well as actual hydrogen evolution rates.

Gases in the cargo holds carrying this cargo shall be removed by extraction, rather than by blowing in the air from outside. Mechanical ventilation exhaust shall be directed to a safe location, away from personnel. All inherent risks associated with the location of the ventilation exhaust openings shall be considered and risk mitigation measures shall be taken to address any such identified potential risk, as appropriate. Ventilation shall be such that exhaust gases cannot enter living quarters in hazardous concentrations. In the event that mechanical ventilation cannot be operated for whatever reason (for example in the event of mechanical breakdown or electrical failure): .1 continuous natural ventilation shall be applied until mechanical ventilation is restored; repairs to the non-functioning ventilator shall, if practicable and safe, be carried out away from cargo holds containing this cargo; a ventilator which cannot readily be repaired shall be replaced with a spare one; .2 if necessary and practicable, use other available means of forced ventilation, preferably in extraction mode; .3 weather routing advice, if available, shall be updated as soon as possible and, where appropriate, consideration shall be given to re-routing and/or adjusting speed to avoid heavy weather; .4 the frequency of monitoring of hydrogen concentration and cargo temperature shall be increased; .5 subject to the discretion of the master, during heavy seas, consideration shall be given to leaving open one or more of the natural vents on the leeward side that are situated in locations protected from the serious effects of the heavy weather, in order to provide some useful dissipation of hydrogen gas from the holds; .6 mechanical ventilation shall be restarted as soon as possible and operated continuously until the concentration of hydrogen falls to or below 0.2% by volume (5% LEL), and thereafter operated, as necessary, to sustain the hydrogen concentration below 1% by volume; .7 due care shall be exercised in restarting the ventilation, both mechanical and natural, so as not to create an ignition source; and .8 seek advice from the shipper or other suitably qualified expert, as appropriate. In all cases, mechanical ventilation shall be operated for an appropriate period of time prior to discharge.

Carriage

The concentrations of hydrogen and oxygen and cargo temperature in holds carrying this cargo shall be measured daily during the voyage in the presence of or by the ship’s designated crew member or representative, or by or under the supervision of the cargo technician, if appointed, and the results of such measurements shall be recorded in a log, given to the master, and kept on board for a minimum of two years. The frequency of monitoring shall be determined on the basis of the information provided by the shipper, the advice of the cargo technician if appointed, and the information obtained through the analysis of the atmosphere in the cargo holds. Consideration shall be given to increasing the frequency of cargo monitoring following periods of bad weather or following mechanical breakdown of the ventilation system.

As soon as the results of monitoring indicate that the hydrogen concentration is approaching or has reached 1% by volume (25% LEL), the following precautionary measures shall be taken: .1 verify proper operation of the mechanical and natural ventilation systems; .2 maintain, and if possible, increase mechanical and natural surface ventilation until the hydrogen concentration falls to or below 0.2% by volume (5% LEL); .3 take care to prevent any spark generation or other potential source of ignition in the vicinity of the cargo holds, adjacent spaces, or open decks; and .4 increase the frequency of monitoring of the hydrogen concentration in the cargo holds with the proper equipment, preferably to hourly, provided always and to the extent that prevailing conditions permit. If the hydrogen concentration remains above 1% by volume after such increased monitoring and ventilation, seek expert advice. Other than in the case of last resort, opening the hatches for the purpose of additional ventilation shall be undertaken only following receipt of relevant expert advice. Personnel shall under no circumstances enter the affected cargo spaces. A cargo temperature of 65°C in a cargo hold is an indicator of a potential emergency situation and is, therefore, a trigger for increased monitoring and vigilance, as well as preparation for dealing with the emergency. In such cases, the following precautionary measures shall be taken: .1 if possible, increase the rate of mechanical and natural ventilation to dissipate heat and any hydrogen; .2 monitor temperatures every 2 to 3 hours and hydrogen concentration every hour if possible, but in any event not less frequently than every 4 hours, provided always and to the extent that prevailing conditions permit; .3 do not use CO2, water or steam on the cargo; .4 monitor hydrogen and oxygen levels in adjacent cargo holds and spaces and if possible, ventilate them; .5 if possible, check for bulkhead heating in adjacent cargo holds; if significant bulkhead heating is detected from within an empty cargo hold, spray with water from the empty cargo hold side, provided the bulkheads are mechanically sound (water shall not be allowed to enter into contact with this cargo); .6 check for signs of abnormal heat in affected sounding pipes and air pipes; and .7 if and when the temperature returns sustainably to 65°C or less, regular monitoring procedures shall be resumed. In the event that the cargo temperature reaches or exceeds 100°C, follow the emergency procedures given in the appendix to this schedule. Bilge wells shall be checked regularly for the presence of water. If water is found, it shall be removed by pumping or draining the bilge wells. In the event that during the voyage the ship begins to exhibit motions indicative of cargo shifting, the appearance of the surface of this cargo shall be checked, subject always to the provisions for safe entry given in the section for “Precautions” hereof. If free water above the cargo or fluid state of the cargo is observed, the master shall take appropriate actions to prevent cargo shifting and potential capsize of the ship and give consideration to seeking emergency entry into a place of refuge.

DIRECT REDUCED IRON (D) (By-product fines with moisture content of at least 2%)

Precautions to be taken by the shipper prior to and during loading

1 The cargo temperature shall be monitored by the shipper for the three days prior to loading to verify temperature stability. Measurements shall be recorded in a log detailing the temperature for each lot of cargo loaded, a copy of which shall be provided to the master prior to sailing. 2 Material exhibiting temperature instability beyond the temporary increase of up to about 30°C or with a temperature above 65°C shall not be loaded. 3 If necessary, once the pre-shipment moisture content has been determined, each pile of cargo to be loaded may be covered with tarpaulins and during loading, the tarpaulins progressively removed as the pile is loaded. In the event of precipitation during loading such that a pile becomes wet, loading from such a pile shall be suspended and, weather permitting, loading shall be resumed from a different pile which has been tested for moisture content. The wet material shall be resampled for moisture content pursuant to 4.5.2 of the IMSBC Code and, such moisture content to be certified as suitable for loading by a competent person recognized by the competent authority of the port of loading. 4 Prior to loading and after loading has been stopped due to precipitation, the shipper shall ensure that the conveyor belts and all other equipment used for loading this cargo contain no accumulations of water or other substances. 5 Each time loading operations are commenced or resumed, all conveyor belts shall be operated unladen, but not over a cargo hold.

Additional precautions to be taken

1 Where practical, ballast tanks adjacent to the cargo holds containing this cargo, other than double-bottom tanks, shall be kept empty. 2 Bilge wells shall be clean, dry and protected from ingress of the cargo with non-combustible material.

8 Prior to loading, an ultrasonic test or another equivalent method shall be conducted to ensure weathertightness of the hatch covers and closing arrangements, and all readings shall confirm weathertightness.

Development of time-based gas prediction curve

A time-based gas prediction curve is an important tool for understanding the likely rate of evolution of hydrogen from this cargo. In order to develop such a curve, a cargo hold shall be ventilated until the hydrogen concentration falls to or below 0.2% by volume (5% LEL), then ventilation (both natural and mechanical) to such hold shall be stopped, and the hydrogen concentration measured every 2 hours thereafter for at least 24 hours or until it reaches 1% by volume, whichever occurs first. If the concentration reaches or exceeds 1% by volume, the respective cargo holds shall be ventilated and measurements continued to ensure that the concentration of hydrogen has stabilized and remains sustainably at or below 0.2% by volume (5% LEL). Based on this data, the length of time needed to reach a concentration of 1% by volume in the absence of ventilation shall be calculated and employed for updating the voyage plan and optimizing the weather routing.

Emergency measures in case of high cargo temperature

1 In the event that the cargo temperature in a hold reaches or exceeds 100°C, the first step is to seek expert advice, in order to determine the best course of action, taking into account the prevailing circumstances and history of the cargo in question; for example, the rate of temperature increase, the remaining sailing time to the scheduled discharge port, etc. 2 Depending on the expert advice received, the following two solutions may be considered: .1 deviation to a port of refuge to discharge the affected cargo if the cargo temperature exceeds 120°C, in which case preparations should be made for grab discharge; and .2 as a last resort and only if safe, flooding the affected cargo holds with water, always taking into account the stability and strength of the ship. 3 The temperatures mentioned in this section, i.e., emergency measures in case of high cargo temperature, are indicative only, and the advice of the appointed surveyor or expert shall be followed.

Duties of the cargo technician

1 The cargo technician, if appointed, shall: .1 Monitor the loading operations and provide advice as appropriate. .2 Advise on and supervise the installation of thermocouples in the cargo holds for temperature monitoring, monitor the performance of the thermocouples, and keep the master informed accordingly; if a cargo technician is not appointed, the shipper shall advise on and supervise the installation of the thermocouples in the cargo holds. .3 Monitor and report on the cargo parameters, namely temperature and hydrogen and oxygen concentrations, as well as other data or information relating directly to cargo behaviour, such duty to include taking readings in conjunction with designated crew members and ensuring that readings are communicated on a regular and frequent basis to the master, or their designated representative, who shall forward them to the shipper to seek appropriate advice. .4 Assist and advise the master and crew in the development of the time-based gas prediction curve and the frequency of updating thereof. .5 Advise and coordinate with the master and crew, as appropriate, in connection with the operation of the ventilation systems.

Toxicity

Arsine is a nerve and blood poison. There is generally a delay before the onset of symptoms (sometimes a day or so). These are at first indefinite.

Symptoms

1 Feeling of malaise, difficulty in breathing, severe headache, giddiness, fainting fits, nausea, vomiting and gastric disturbances. 2 In severe cases, vomiting may be pronounced, the mucous membranes may have a bluish discolouration and urine is dark and bloodstained. After a day or so there is severe anaemia and jaundice.

Concentration

A concentration of 500 ppm is lethal to humans after exposure of a few minutes, while concentrations of 250 ppm are dangerous to life after 30 min exposure. Concentrations of 6.25 to 15.5 ppm are dangerous after exposure of 30 to 60 min. A concentration of 0.05 ppm is the threshold long limit to which a person may be exposed.

(ii) Phosphine

Phosphine is colourless, flammable and highly toxic and has the odour of rotting fish.

Toxicity

Phosphine acts on the central nervous system and the blood.

Symptoms

The symptoms exhibited by phosphine poisoning are an oppressed feeling in the chest, headache, vertigo, general debility, loss of appetite and great thirst. Concentrations of 2,000 ppm for a few minutes and 400 to 600 ppm are dangerous to life. 0.3 ppm is the maximum concentration tolerable for several hours without symptoms.
