The 9 Classes of Dangerous Goods

What are considered dangerous goods?

Dangerous goods are materials or items with hazardous properties which, if not properly controlled present a potential hazard to human health and safety, infrastructure and/or their means of transport.

Dangerous goods, often recognised as hazardous materials, may be pure chemicals, mixtures of substances, manufactured products or articles which can pose a risk to people, animals or the environment if not properly handled in use or in transport.

Transportation of hazardous materials

The UN Model Regulations use a classification system in which each dangerous substance or article is assigned to a CLASS, depending on the nature of the danger it presents. There are 9 Classes, some of which are sub-divided.
