Recommendations on the Transport of Dangerous Goods – Model Regulations (Rev.21)

Published: October 2019

These recommendations have been developed in the light of technical progress, the advent of new substances and materials, the exigencies of modern transport systems and, above all, the requirement to ensure the safety of people, property and the environment. They are addressed to governments and international organisations concerned with the regulation of the transport of dangerous goods. The Model Regulations cover the classification of dangerous goods, their listing, the use, construction, testing and approval of packagings and portable tanks, as well as consignment procedures such as marking, labelling, placarding and documentation. 

This twenty-first revised edition contains various new and revised provisions concerning, inter alia, electric storage systems (including lithium batteries installed in cargo transport units and defective batteries), explosives, infectious waste of Category A, waste gas cartridges, harmonization with the 2018 Edition of IAEA's Regulations for the Safe Transport of Radioactive Material, listing of dangerous goods, update of LC₅₀ values for some toxic gases and use of in vitro skin corrosion methods for classification.
