9.3.4 Segregation between solid bulk cargoes possessing chemical hazards

Unless otherwise required in this section or in the individual schedules for cargoes of Group B, segregation between solid bulk cargoes possessing chemical hazards shall be according to the following table:

Solid bulk materials
	Class/ division	4.1	4.2	4.3	5.1	6.1	7	8	9	MHB
Flammable solids	4.1	X
Substances liable to spontaneous combustion	4.2	2	X
Substances which, in contact with water, emit flammable gases	4.3	3	3	X
Oxidizing substances	5.1	3	3	3	X
Toxic substances	6.1	X	X	X	2	X
Radioactive materials	7	2	2	2	2	2	X
Corrosive substances	8	2	2	2	2	X	2	X
Miscellaneous dangerous substances and articles	9	X	X	X	X	X	2	X	X
Materials hazardous only in bulk (MHB)	MHB	X	X	X	X	X	2	X	X	X

Numbers relate to the following segregation terms:

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”:
	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.
X	Segregation, if any, is shown in the individual schedules in this Code.
	Legend
	Reference bulk material
	Incompatible bulk material
	Deck resistant to liquid and fire
