Which division corresponds to a mass detonation hazard?

Which division corresponds to a mass detonation hazard?

• A. Division 1
• B. Division 2
• C. Division 3
• D. Division 4

Answer: (A)

Mass detonation hazard refers to explosives that could detonate with blast effects significant enough to involve a large amount of material, not just a small, contained explosion. In the classification system for explosives, this type of hazard is assigned to the division that covers materials with mass detonation potential. The other divisions are associated with different hazard profiles—such as fire hazards, minor explosions, or insensitivity—and do not indicate mass detonation risk. Therefore, the division that corresponds to a mass detonation hazard is the one designated for explosives with mass detonation potential.
