The blast-injury category that includes crush injuries, burns, asphyxia, and toxic exposures?

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

Answer: (D)

In blast injuries, there are four mechanism-based categories. The first three explain injuries from the blast wave itself (primary), from flying debris (secondary), and from the body being thrown and struck (tertiary). The remaining injuries that don’t fit those mechanisms—such as burns from fires, inhalation injuries, crush injuries from collapsing structures, asphyxia, and exposure to toxins—are grouped as quaternary blast injuries. This category captures the broader, non-mechanical effects of an explosion. So the pattern that includes crush injuries, burns, asphyxia, and toxic exposures is quaternary blast injuries.
