Which blast injury type causes the most blunt trauma?

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

Answer: (C)

In blast injuries, the way the force transfers to the body creates distinct injury patterns. The most blunt trauma comes from the body being thrown by the blast wind and then striking nearby objects. This blunt impact can cause widespread contusions, fractures, head injuries, chest trauma, and crush injuries as the person collides with walls, the ground, or debris. Secondary injuries come from fragments and shrapnel penetrating tissues, producing penetrating wounds rather than broad blunt damage. Primary injuries are due to the blast overpressure itself, affecting gas-filled organs like the ears and lungs, not from blunt contact. Quaternary injuries are miscellaneous effects such as burns, inhalation injuries, or worsened existing conditions, and aren’t defined by blunt force trauma.
