Which term describes the debris and material expelled by an explosion that can pose hazards to personnel and equipment?

• A. Blast
• B. Ejecta/debris
• C. Penetration
• D. Thermal

Answer: (B)

Ejecta/debris describes the solid material hurled outward when an explosion occurs. This includes fragments from the device, its casing, and surrounding objects that are shattered or melted and propelled at high speed. Because these fragments can travel far from the blast and strike personnel and equipment, they’re a major hazard separate from the blast shockwave and from heat radiation. The term blast refers to the overpressure shockwave itself, which can cause damage through pressure and movement. Thermal describes heat and fire effects. Penetration relates to the ability of a projectile to pierce armor, not the debris generated by the explosion. So the debris and material expelled by an explosion are best described as ejecta/debris.
