CLASS 1 (EXPLOSIVES) DANGEROUS GOODS TRANSPORTATION

Class 1 Dangerous Goods – Explosives

Dangerous Goods which are classed as Explosives are materials or items which have the ability to rapidly conflagration or detonate as a consequence of chemical reaction.

Sub-Divisions

1.1: Substances and articles which have a mass explosion hazard.

1.2: Substances and articles which have a projection hazard but not a mass explosion hazard.

1.3: Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both.

Organic peroxides are thermally unstable and may exude heat whilst undergoing exothermic autocatalytic decomposition. Additionally, organic peroxides may be liable to explosive decomposition, burn rapidly, be sensitive to impact or friction, react dangerously with other substances or cause damage to eyes.
