Penetrating trauma caused by shrapnel is usually attributed to which blast effect?

Explanation:
Penetrating injuries from an explosion come from fragments and debris propelled by the blast. These projectiles strike the body at high velocity, causing puncture wounds and lacerations—that's the secondary blast effect. The blast overpressure wave itself tends to injure air-filled organs and is categorized as the primary effect, while the wind from the blast can throw a person, leading to impact injuries (tertiary effect). Additional burns or exposures fall under quaternary effects. So when shrapnel causes penetrating trauma, the mechanism is the secondary blast effect—the fragments acting as missiles.
