Which division is described as extremely insensitive explosives?

• A. Explosives Division 1.4
• B. Gas Division 2.3
• C. Explosives Division 1.6
• D. Explosives Division 1.1

Answer: (C)

Explosives are categorized by how sensitive they are to initiation. Extremely insensitive explosives belong to Division 1.6, which covers extremely insensitive detonating explosives (EIDE). This means they have a very low probability of detonation under normal conditions and would require a strong initiating event to detonate. Other divisions describe different levels of risk: Division 1.1 involves mass explosion hazards, Division 1.4 involves no significant blast or projection beyond the packaging, and Division 1.5 covers very insensitive explosives with a mass explosion hazard but are more initiable than 1.6. Gas 2.3 refers to toxic gas, not an explosive. So the division described as extremely insensitive explosives is Division 1.6.
