WORK OF THE SUB-COMMITTEE OF EXPERTS ON

THE TRANSPORT OF DANGEROUS GOODS

Allocation of substances to tanks

Information Paper from the International Maritime Organisation (IMO)

1.	During its last session (14-23 September 1998) the DSC Sub-Committee's Editorial and Technical Group (E&T Group) amongst others, discussed the allocation of substances to tanks.

2.	The E&T Group agreed that the allocation of substances to tanks should be according to the principle of the rationalized approach as developed by the UN Committee of Experts.

3.	The E&T Group considered the transportation of substances identified as highly corrosive to steel in the existing IMDG Code in tanks with bottom openings and it was agreed that such substances should not be transported in these tanks.

4.	Furthermore, it was agreed that the list of substances classified as highly corrosive to steel in the IMDG Code need to be reviewed.

Proposals:

5.	Substances that are identified as highly corrosive to steel in the existing IMDG Code should not be permitted to be transported in tanks with bottom openings.

6.	Note the impending review of the list of substances in the IMDG Code that are highly corrosive to steel by the DSC Sub-Committee.
