Hazardous materials that pose a chemical threat burn on contact or absorb into the body and through time destroy organs. This threat is called what?

• A. Infection
• B. Thermal
• C. Chemical
• D. Mechanical

Answer: (C)

Hazards are classified by how they harm the body. A chemical threat involves substances that burn on contact or are absorbed into the body, and can cause organ damage over time. The description here—burning on contact or absorption with potential delayed organ destruction—fits chemical hazards. In contrast, infection comes from living organisms, thermal refers to heat-related burns, and mechanical injuries come from physical forces. So the hazard described is chemical.
