Injuries that occur when the human body is propelled by the blast pressure wave and impacts the ground, structures, or other stationary objects are classified as which type?

• A. Primary blast injuries
• B. Secondary blast injuries
• C. Tertiary blast injuries
• D. Quaternary blast injuries

Answer: (C)

When the blast force throws the body through the air and it hits the ground or surrounding objects, the resulting injuries are tertiary blast injuries. The key idea is blunt trauma from being displaced by the blast wind and then colliding with surfaces, which can produce fractures, head injuries, spinal injuries, and other blunt-force damage. This differs from primary blast injuries, which come from the overpressure of the blast wave acting on air-filled organs, secondary blast injuries from shrapnel or debris, and quaternary blast injuries from other explosion-related factors like burns or inhalation of gases. So the best description is injuries caused by the body being propelled by the blast wind and impacting objects, i.e., tertiary blast injuries.
