TRANSPORT OF DANGEROUS GOODS DOCUMENTATION

Comments on Document ST/SG/AC.10/1998/42

Transmitted by the Experts from the United States of America

1.	The expert from the United States supports in principle the proposal in ST/SG/AC.10/1998/42 by Austria with respect to substances that require stabilization in order to ensure safe transport. Substances that include the word "stabilized" in the shipping name are subject to 3.1.1.4 whereas other substances requiring stabilization but which are transported under a name that does not include the word stabilized are not subject to this provision.

2.	With respect to the proposal in ST/SG/AC.10/1998/42, the following additional points are offered:

-	some substances require stabilization for other than safe transport reasons (e.g.; product quality). Such substances should not be subject to the proposed requirement. Only substances which without stabilization would be forbidden from transport in accordance with 1.1.3 should be subject to the proposed requirement.

-	the word INHIBITED was replaced by the word STABILIZED in all shipping descriptions in the 11th revised edition.

-	this provision should not apply to organic peroxides and self-reactive substances where the concern for reaction is already dealt with.

3.	It is proposed that the proposal be reworded as follows:

"3.1.2.6 Except for self-reactive substances and organic peroxides and unless it is already included in capital letters in the name indicated in the Dangerous Goods List, the word STABILIZED shall be added as part of the proper shipping of a substance which without stabilization would be forbidden from transport in accordance with 1.1.3 due to it being liable to dangerously react under conditions normally encountered in transport."
