What hazard is associated with explosives when involved in or near a fire?

• A. They release energy rapidly
• B. They absorb heat and become inert
• C. They become harmless
• D. They only explode underwater

Answer: (A)

When explosives are exposed to a fire, the danger is that they release energy rapidly. Heat from the fire can push the explosive toward its initiation threshold, triggering detonation or a very fast decomposition. That rapid energy release creates a powerful blast wave and flying fragments, which can cause catastrophic damage and injuries. Explosives do not become inert or harmless from heat, nor are they restricted to underwater explosions—the real hazard in a fire is the sudden, high-energy release.
