Class 1: Explosives

General Information:

Class 1 covers substances and articles that can cause explosion, rapid release of gas or violent reaction. These materials are tightly regulated because of their extreme hazard potential. Class 1 has six divisions based on the kind and degree of explosive risk.

Under New Zealand regulations, handling of many Class 1 explosives requires a Controlled Substance License (CSL), and strict safety requirements must be followed in transport and handling. Controlled Substance License's (CSL) are issued by WorkSafe.

Class 1 Divisions:

• Division 1.1 - Substances and articles which have a mass explosion hazard
• Division 1.2 - Substances and articles which have a projection hazard but not a mass explosion hazard
• Division 1.3 - Substances and articles which have a fire hazard and either a minor blast hazard or a minor projection hazard or both.
• Division 1.4 - Substances and articles which present no significant hazard.
• Division 1.5 - Very insensitive substances which have a mass explosion hazard
• Division 1.6 - Extremely insensitive articles which do not have a mass explosion hazard.

• Chain reactions if stored improperly or mixed with incompatible substances
