Dangerous Goods are grouped in nine classes, according to common dangers. All classes, except infectious substances (Class 6.2) and radioactive substances (Class 7), are controlled by the Dangerous Goods Act 1985.
Each class has a distinctive diamond-shaped symbol with the class number at the bottom of the diamond. These symbols appear on the labels of containers and as signs on vehicle loads. The internationally recognised symbols clearly identify the type of substance and the main danger.
