Injuries sustained from the direct effect of the blast pressure wave on the human body are classified as which type of blast injuries?

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

Answer: (A)

The direct impact of the blast pressure wave on the body causes primary blast injuries. This injury type results from the rapid overpressure of the blast acting on air-filled organs and membranes, leading to damage such as tympanic membrane rupture and pulmonary barotrauma. Other blast injuries come from different mechanisms: debris or shrapnel causing secondary injuries, the body being thrown and colliding with objects causing tertiary injuries, and additional explosion effects like burns or inhalation of toxins causing quaternary injuries. So the injuries produced specifically by the blast pressure wave itself are classified as primary blast injuries.
