TRACEMP includes hazard categories such as Thermal, Radiological, Asphyxiation, Chemical, Etiological, Mechanical, Psychological. Which of the following is NOT a TRACEMP category?

• A. Biochemical
• B. Thermal
• C. Radiological
• D. Asphyxiation

Answer: (A)

TRACEMP groups the hazards firefighters watch for into seven domains to guide safety controls: Thermal, Radiological, Asphyxiation, Chemical, Etiological, Mechanical, and Psychological. Biochemical isn’t listed because biological hazards are covered by the Etiological category in this framework. Thermal covers heat or cold, Radiological deals with radiation, Asphyxiation involves oxygen deficiency or gases that displace it, Chemical is for hazardous chemicals, Mechanical refers to physical hazards from equipment or debris, and Psychological addresses stress and mental/behavioral factors. So Biochemical doesn’t fit the established TRACEMP categories.
