All other injuries from blast, including crush injuries, burns, asphyxia, and toxic exposures, fall under which category?

All other injuries from blast, including crush injuries, burns, asphyxia, and toxic exposures, fall under which category?

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

Answer: (B)

In blast injuries, the four-category framework helps clinicians anticipate and manage harm: injuries from the initial overpressure (primary), from flying debris (secondary), from the body being thrown or crushed by the blast wind (tertiary), and all other effects related to the blast environment (quaternary). All other injuries from a blast—including crush injuries from structural collapse, burns from heat or flames, asphyxia from smoke or confined-space exposure, and toxic exposures released by the explosion—fall into the quaternary category. This category covers the miscellaneous or secondary consequences not explained by the first three mechanisms, and it guides focused care such as airway management for inhalation injuries, burn care, treatment of crush syndrome, and management of chemical or toxin exposure.
