WORK OF THE SUB-COMMITTEE OF EXPERTS

ON THE TRANSPORT OF DANGEROUS GOODS

Draft amendments to the Model Regulations

Part 7: Provisions concerning transport operations

Mixed transport of goods of Class 1

with other dangerous goods

Transmitted by the expert from Norway

1.	Introduction

Paragraph 7.1.3 contains provisions regarding the segregation of goods of Class 1 of different compatibility groups. There also exists a practical need for transporting certain explosive substances and articles together with other dangerous goods. Such provisions for mixed transport already exists in RID/ADR and ICAO-TI/IATA-DGR for transport of explosives classified as 1.4S together with other dangerous goods, and in the IMDG-code for stowage of blasting explosives together with ammonium nitrate and sodium nitrate of Division 5.1. There also exists various national regulations and multinational agreements for transporting certain explosives together with other dangerous goods.

GE.98-

The Expert from Norway presented in doc. ST/SG/AC.10/C.3/1998/11 a proposal to the Sub-Committee to include in the Model Regulations some indication on such mixed transport provisions in Chapter 7.1.3, based upon the texts in existing regulations . It was indicated during the discussions on this document that there was a general agreement that the Model Regulations should contain provisions for mixed carriage of goods of Class 1 with dangerous goods of other classes, but there were numerous comments made on details in the Norwegian proposal. Based upon the comments made, and decisions taken on other proposals at the fifteenth session of the Sub-Committee, Norway will propose the following amendments to the Model Regulations.
