Which term describes hazardous materials that pose threat to first responders due to extreme temperatures?

• A. Thermal
• B. Radioactive
• C. Toxic
• D. Explosive

Answer: (A)

Extreme temperatures creating danger to responders describes a thermal hazard. The core risk here is heat or extreme cold affecting people and equipment—burns, frostbite, or materials reacting unpredictably when exposed to very high or very low temperatures. In incident response, you’d focus on limiting heat transfer, using cooling or insulation as needed, and staying at safe distances with appropriate shielding and PPE to prevent temperature-related injuries or container failures. The other terms point to different hazards: radioactive hazards come from radiation, toxic hazards from chemical poisoning, and explosive hazards from sudden, violent energy release. Those hazards may be present in some incidents, but the description in this question centers on temperature-related danger, making thermal the correct term.
