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 twentieth revised edition contains various new and revised provisions concerning, inter alia, articles which contain dangerous substances or articles; the classification of ammonium nitrate-based fertilizers; the classification of corrosive mixtures; the stabilization of fishmeal to prevent self-heating; cargo transport units containing lithium batteries and used for electricity storage; packing instruction for defective or damaged lithium batteries; the availability of test reports for lithium batteries; the transport of unstable substances under temperature control and the transport of vehicles powered by flammable liquids or gases, fuel cells or batteries.
