9.3.1 General requirements

  9.3.1.1 The potential hazards of the cargoes in Group B and falling within the classification of 9.2.2 and 9.2.3 entail the need for segregation of incompatible cargoes. Segregation shall also take account of any identified subsidiary risk.

  9.3.1.2 In addition to general segregation as between whole classes of materials there may be a need to segregate a particular material from others. In the case of segregation from combustible materials this shall be understood not to include packaging material, ceiling or dunnage; the latter shall 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 plating and 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, the segregation 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, the most stringent segregation provisions applicable to any of the different grades shall apply to all of them.

  9.3.1.6 When solid bulk cargoes of Group B and dangerous goods in packaged form are to be carried, the segregation between them shall be in accordance with 9.3.3.

  9.3.1.7 Incompatible materials shall not be handled simultaneously. Upon completion of loading one cargo, the hatch covers of every cargo space shall be closed and the decks cleaned of residue before the loading of other material is commenced. When discharging, the same procedures shall be followed.

  9.3.1.8 To avoid contamination, all foodstuffs shall be stowed:

  • .1 “separated from” a material which is indicated as toxic;

  • .2 “separated by a complete compartment or hold from” all infectious materials;

  • .3 “separated from” radioactive materials; and

  • .4 “away from” corrosive materials.

  • The terms are defined in 9.3.3 and 9.3.4, as appropriate.

  9.3.1.9 Materials which may evolve toxic gases in sufficient quantities to affect health shall not be stowed in those spaces from where such gases may penetrate into living quarters or ventilation systems connecting to living quarters.

  9.3.1.10 Materials which present corrosive hazards of such intensity as to affect either human tissue or the ship's structure shall only be loaded after adequate precautions and protective measures have been taken.

  9.3.1.11 After discharge of toxic or oxidizing cargoes, the spaces used for their carriage shall be inspected for contamination before being used for other cargoes. A space which has been contaminated shall be properly cleaned and examined before being used for other cargoes.

  9.3.1.12 After discharge of cargoes, a close inspection shall be made for any residue, which shall be removed before the ship is presented for other cargoes.

  9.3.1.13 For cargoes for which in case of an emergency the hatches shall be opened, these hatches shall be kept free to be capable of being opened up.
