COMMITTEE OF EXPERTS ON THE

TRANSPORT OF DANGEROUS GOODS

(Twentieth session,

Geneva, 7-16 December l998,

agenda item 2 (d))

WORK OF THE SUB-COMMITTEE OF EXPERTS ON

THE TRANSPORT OF DANGEROUS GOODS

Draft amendments to the Model Regulations

on the Transport of Dangerous Goods

New proposals

Transport Document

Transmitted by the Expert from Canada

Introduction

1.	The purpose of this document is to make provision for the optional addition of the subsidiary risk(s) of dangerous goods, as determined through the Dangerous Goods List, on the dangerous goods transport document.

Discussion

2.	Subsidiary risk placards must be displayed for certain dangerous goods. As recognized in paragraph 5.3.1.1.3, a transport unit may contain goods of more than one class and one of these may require the display of a subsidiary risk placard. Unless the subsidiary risk is shown on the transport document, a responder may not know to which goods the subsidiary risk placard applies. A similar discussion applies to labels. Further, the presence of a subsidiary risk will likely not be overlooked by an emergency responder if it appears next to the primary risk.

3.	The proposal would allow, for example, the transport document entries for UN1868 and UN1660 to be:

DECABORANE, 4.1 (6.1), UN1868, Packing Group II, (quantity); and,

NITRIC OXIDE, COMPRESSED, 2.3 (5.1, 8), UN1660, (quantity).

Proposal

4.	Add a new paragraph, 5.4.1.1.1.1, to read as follows:

"5.4.1.1.1.1	In addition to the information required to be on a transport document according to paragraph 5.4.1.1.1, the subsidiary risk(s) of the dangerous goods as determined through the Dangerous Goods List may be added in parenthesis following the class or, when assigned, the division of the goods."
