Hazardous materials that pose a threat to first responders because they are too hot or too cold are described as which type?

• A. Radioactive
• B. Thermal
• C. Chemical
• D. Biological

Answer: (B)

Extreme temperatures create a separate hazard category for responders called thermal hazards. When a material is very hot, it can cause burns, steam burns, or ignite surrounding materials, while extremely cold substances can cause cryogenic burns and other cold-related injuries or rapid vapor release that can create dangerous atmospheres. This type is distinct from radioactive hazards (radiation exposure), chemical hazards (toxicity or reactivity), and biological hazards (pathogens). So when a material is described as being too hot or too cold, it’s the thermal hazard at work. For example, liquid nitrogen presents a cryogenic thermal hazard, and molten substances present a heat-based thermal hazard.
