Carriage Of Dangerous Goods

Dangerous goods, also called hazardous materials are solids, liquids, or gases that can harm people, other living organisms, property, or the environment. They are often subject to chemical regulations. Dangerous goods include materials that are radioactive, flammable, explosive or corrosive, oxidizers or asphyxiants, biohazardous, toxic, pathogen or allergen substances and organisms. Also included are physical conditions such as compressed gases and liquids or hot materials, including all goods containing such materials or chemicals, or may have other characteristics that render them hazardous in specific circumstances.

The colours of each diamond in a way has reference to its hazard ie: Flammable = red, Explosive = orange, because mixing red (flammable) with yellow (oxidising agent) creates orange. Non Flammable Non Toxic Gas = green, due to all compressed air vessels being this colour in France after World War II. France is where the diamond system of HazMat identification originated.

Packing groups

Packing groups are used for the purpose of determining the degree of protective packaging required for Dangerous Goods during transportation.

• Group I: great danger, and most protective packaging required
• Group II: medium danger
• Group III: least danger among regulated goods, and least protective packaging within the transportation requirements
