Blast injuries from displacement of the victim by the blast wind, causing blunt or penetrating trauma and fractures?

• A. Quaternary Blast Injuries
• B. Tertiary Blast Injury
• C. Primary Blast Injury
• D. Secondary Blast Injury

Answer: (B)

When a blast occurs, the energy can push the body through the air. That displacement and impact with surrounding objects causes tertiary blast injuries. These injuries are characterized by blunt trauma or penetrating injuries and fractures resulting from being hurled and struck by debris or surfaces after the explosion. This differs from primary injuries, which come from the blast overpressure affecting air-containing organs; secondary injuries, which come from projectiles like shrapnel; and quaternary injuries, which include burns, inhalation injuries, or other blast-related effects not related to the body being thrown.

So the description of injuries from being displaced by the blast wind and hitting objects—causing blunt or penetrating trauma and fractures—fits tertiary blast injuries.
