In blast injuries, tertiary blast injury is caused by which mechanism?

• A. The blast itself
• B. Shrapnel
• C. Body being thrown against a solid object
• D. Heat of explosion

Answer: (C)

Tertiary blast injury occurs when the blast wind propels the body and it crashes into a solid object. The impact causes blunt trauma, which can include fractures, head injuries, chest or abdominal trauma, and other internal injuries depending on what was struck and the force of the throw. This is different from injuries caused by the blast overpressure itself (primary injuries) or by flying fragments (secondary injuries). The heat from the explosion leads to burns, which are a separate mechanism.
