Which hazard class division is assigned to materials capable of a mass explosion?

• A. 1.4
• B. 1.3
• C. 1.2
• D. 1.1

Answer: (D)

Mass explosion capability is the highest hazard designation within Class 1 explosives, meaning detonation can involve a large portion or the entire charge and create a blast that affects a wide area. This division is specifically reserved for materials that can produce a mass explosion, distinguishing them from explosives with only a projection hazard or primarily a fire hazard, or from the more insensitive divisions that have much lower risk. So, materials capable of a mass explosion are categorized under the division that indicates mass explosion hazards.
