What are the four types of blast injuries?

• A. Thermal, Chemical, Electrical, Mechanical.
• B. Direct, Indirect, Peripheral, Central.
• C. Primary (pressure wave), Secondary (penetrating), Tertiary (blunt), and Quaternary (other).
• D. Internal, External, Surface, Deep.

Answer: (C)

Blast injuries are categorized by how the blast force affects the body, into four types: primary injuries come from the initial overpressure wave and most commonly damage air-filled organs such as the ears, lungs, and gastrointestinal tract; secondary injuries result from flying fragments and cause penetrating wounds; tertiary injuries occur when the body is thrown by the blast wind, leading to blunt trauma and crush injuries; and quaternary injuries cover all other explosion-related effects, including burns, inhalation injuries, asthma exacerbations, and exposure to toxic substances. This framework helps responders quickly anticipate likely injury patterns, guide focused assessment, and prioritize treatment in the field. Other groupings don’t match the blast-specific mechanisms in this way, so they don’t capture the full range of explosion-related injuries.
