9.3.3 Segregation between bulk materials possessing chemical hazards and dangerous goods in packaged form

  9.3.3.1 Unless otherwise required in this section or in the individual schedules, segregation between solid bulk cargoes of Group B and dangerous goods in packaged form shall be in accordance with the following table.

 9.3.3.2 The Dangerous Goods List of the IMDG Code shall be consulted for additional requirements with regard to stowage and segregation of packaged dangerous goods.

 Numbers relate to the following segregation terms:

1 “Away from”:
  Effectively segregated so that incompatible materials cannot interact dangerously in the event of an accident but may be carried in the same hold or compartment or on deck provided a minimum horizontal separation of 3 metres, projected vertically, is provided.
2 “Separated from”:
  In different holds when stowed under deck. Provided an intervening deck is resistant to fire and liquid, a vertical separation, i.e. in different compartments, may be accepted as equivalent to this segregation.
3 “Separated by a complete compartment or hold from”:
  Means either a vertical or a horizontal separation. If the decks are not resistant to fire and liquid, then only a longitudinal separation, i.e. by an intervening complete compartment, is acceptable.
4 “Separated longitudinally by an intervening complete compartment or hold from”:
  Vertical separation alone does not meet this requirement.
X Segregation, if any, is shown in the Dangerous Goods List of the IMDG Code or in the individual schedules in this Code.
