Which hazards are associated with MPPEH?

• A. Unexploded ordnance, detonation, or sympathetic detonation
• B. Fire hazard only
• C. Chemical poisoning
• D. None

Answer: (A)

When working with MPPEH, the primary risk is the explosive energy inside munitions. The hazards you must expect are unexploded ordnance that may still contain a live charge, the possibility of detonation during handling or movement, and the chance of sympathetic detonation where one explosion can initiate nearby munitions. That’s why the best answer is the one that highlights these explosive-related hazards. A fire-only hazard doesn’t capture the immediate risk of detonation from handling, heat, or shock, and chemical poisoning isn’t the central danger in MPPEH situations (though some components can be toxic, the core risk is explosive energy). Never assume safety; treat unknown ordnance as potentially armed and follow proper EOD procedures to establish a safe clearance.
