What are the three classifications of explosives?

• A. High velocity explosives
• B. Detonators
• C. Blasting agents
• D. All of the above

Answer: (D)

Explosives are classified by how they behave and how they’re used in a blast. The three classifications cover high velocity explosives, blasting agents, and detonators. High velocity explosives detonate rapidly and deliver a strong shock wave. Blasting agents are energetic materials used as the main charge and designed for controlled blasting, often needing a booster to detonate. Detonators are initiation devices that trigger the explosive charge. Since each category represents a distinct part of a blasting system, all three are acknowledged as classifications, making “all of the above” the best choice. Examples: high velocity explosives include TNT or RDX; blasting agents include ANFO and emulsions; detonators include blasting caps or electric detonators.
