UN Recommendations on the Transport of Dangerous Goods

The UN Recommendations on the Transport of Dangerous Goods are rules created by experts from the United Nations Economic and Social Council. These rules help countries make sure dangerous materials are moved safely. They cover things like chemicals, explosives, and other items that could be risky if not handled properly.

These recommendations are not laws that countries must follow, but many countries use them to create their own rules. They help make transport by road, rail, air, and sea safer for everyone. The rules do not talk about making or using these materials, only moving them.

Dangerous goods are grouped into nine classes based on the risks they pose. Each common dangerous material has a special four-digit code called a UN number, like TNT or fireworks. This helps everyone know what they are dealing with and how to handle it safely.

History and principles

The first version of the Recommendations on the Transport of Dangerous Goods was created in 1956 by a group of experts from the United Nations. Starting in 1996, these recommendations were divided into two parts: the Model Regulations, which suggest rules for laws about moving dangerous goods, and the Manual of Tests and Criteria, which gives technical details on how to test products for safety.

Countries use these recommendations to create their own rules, with groups like Transport Canada and the United States Department of Transportation applying them. Some companies may have extra rules too.
