MSC 85/26/Add.2ANNEX 3Page 38Section 9Materials possessing chemical hazards9.1 GeneralSolid bulk cargoes which may possess a chemical hazard during transport, because of theirchemical nature or properties, are in Group B. Some of these materials are classified asdangerous goods and others are materials hazardous only in bulk (MHB). It is essential to obtaincurrent, valid information about the physical and chemical properties of the cargoes to be shippedin bulk, prior to loading.9.2 Hazard classification9.2.1 The classification of materials possessing chemical hazards and intended to be shipped inbulk under the requirements of this Code shall be in accordance with 9.2.2 and 9.2.3.9.2.2 Classification of dangerous goodsSOLAS regulation VII/7 defines dangerous goods in solid form in bulk. For the purpose ofthis Code, dangerous goods shall be classified in accordance with part 2 of the IMDG Code.9.2.2.1 Class 4.1: Flammable solidsThe materials in this class are readily combustible solids and solids which may cause firethrough friction.9.2.2.2 Class 4.2: Substances liable to spontaneous combustionThe materials in this class are materials, other than pyrophoric materials, which, in contact withair without energy supply, are liable to self-heating.9.2.2.3 Class 4.3: Substances which, in contact with water, emit flammable gasesThe materials in this class are solids which, by interaction with water, are liable to becomespontaneously flammable or to give off flammable gases in dangerous quantities.9.2.2.4 Class 5.1: Oxidizing substancesThe materials in this class are materials while in themselves not necessarily combustible, may,generally by yielding oxygen, cause, or contribute to, the combustion of other material.9.2.2.5 Class 6.1: Toxic substancesThe materials in this class are materials liable either to cause death or serious injury or to harmhuman health if swallowed or inhaled, or by skin contact.I:\MSC\85\26-Add-2.doc
MSC 85/26/Add.2ANNEX 3Page 399.2.2.6 Class 7: Radioactive materialThe materials in this class are any materials containing radionuclides where both the activityconcentration and the total activity in the consignment exceed the values specified in 2.7.7.2.1to 2.7.7.2.6 of the IMDG Code.9.2.2.7 Class 8: Corrosive substancesThe materials in this class are materials which, by chemical action, will cause severe damagewhen in contact with living tissue or will materially damage, or even destroy, other goods or themeans of transport.9.2.2.8 Class 9: Miscellaneous dangerous substances and articlesThe materials in this class are materials and articles which, during transport, present a danger notcovered by other classes.9.2.3 Materials hazardous only in bulk (MHB)These are materials which may possess chemical hazards when transported in bulk other thanmaterials classified as dangerous goods in the IMDG Code.9.3 Stowage and segregation requirements9.3.1 General requirements9.3.1.1 The potential hazards of the cargoes in Group B and falling within the classificationof 9.2.2 and 9.2.3 entail the need for segregation of incompatible cargoes. Segregation shall alsotake account of any identified subsidiary risk.9.3.1.2 In addition to general segregation as between whole classes of materials there may be aneed to segregate a particular material from others. In the case of segregation from combustiblematerials this shall be understood not to include packaging material, ceiling or dunnage; the lattershall in these circumstances be kept to a minimum.9.3.1.3 For the purpose of segregating incompatible materials, the words “hold” and“compartment” are deemed to mean a cargo space enclosed by steel bulkheads or shell platingand by steel decks. The boundaries of such a space shall be resistant to fire and liquid.9.3.1.4 When two or more different solid bulk cargoes of Group B are to be carried, thesegregation between them shall be in accordance with 9.3.4.9.3.1.5 Where different grades of a solid bulk cargo are carried in the same cargo space, themost stringent segregation provisions applicable to any of the different grades shall apply to allof them.9.3.1.6 When solid bulk cargoes of Group B and dangerous goods in packaged form are to becarried, the segregation between them shall be in accordance with 9.3.3.I:\MSC\85\26-Add-2.doc
