Emergency Response And Vehicle Extrication Key Concepts And Safety Protocols Practice Test

Which statement correctly describes secondary blast injuries?

Primary blast injuries involve the pressure wave. Secondary blast injuries involve penetration of projectiles and debris. Tertiary blast injuries involve the body being thrown. Quaternary blast injuries involve chemical exposure.

Correct Answer:

Secondary blast injuries involve penetration of projectiles and debris.

Explanation:

Secondary blast injuries occur when fragments and debris from the explosion penetrate the body. The forceful shattering of the device and surrounding materials sends projectiles flying, causing penetrating wounds and tissue damage from these fragments. This mechanism is distinct from primary injuries, which come from the blast’s pressure wave and mainly affect air-filled organs; tertiary injuries result from the body being thrown and hitting objects; quaternary injuries include burns, inhalation injuries, and other blast-related effects from chemical exposure. So describing secondary injuries as involving penetration by projectiles and debris best captures the actual mechanism at work.
