Dangerous goods are materials or items with hazardous properties which, if not properly controlled, pose a potential risk to human health and safety, infrastructure and/or their means of transport.
The International Civil Aviation Organization (ICAO) Technical Instructions are a set of internationally agreed provisions governing the requirements for the transport of dangerous goods by air. The International Air Transport Association (IATA) publishes Dangerous Goods Regulations in accordance with the ICAO Technical Instructions.
Dangerous goods, often recognized as harmful materials, can be pure chemicals, mixtures of substances, manufactured products or articles that may pose a risk to people, animals or the environment if not handled correctly during use or during transport.
The Model UN Regulations use a classification system in which each hazardous substance or article is assigned to a CLASS, depending on the nature of the hazard it presents. There are 9 classes, some of which are further subdivided into others. Click on the class for more information:
3. Flammable Liquids
