Which term is not part of the three classifications of explosives?

• A. High velocity explosives
• B. Detonators
• C. Fuzes
• D. Blasting agents

Answer: (C)

Explosives in blasting are grouped by what they are and how they contribute to the blast. The common three classifications are blasting agents, which are the bulk energetic materials used to create the blast; high velocity explosives, which are energetic materials with fast detonation speeds that drive efficient rock breakage; and detonators, the initiation devices that start the explosive chain reaction. Fuzes, while important in the initiation system, are not a type of explosive material themselves. They are timing or delay devices used with detonators, so they don’t belong to the three classifications of explosives. That’s why the term not part of the classifications is fuzes.
