Which term describes a material having a temperature exceeding 57°C (134.6°F)?

• A. Hot Material
• B. Explosive
• C. Inhabited Building
• D. Leaching

Answer: (A)

Hot material is the term used for substances that are hot enough to pose a burn hazard, specifically above a threshold like 57°C. At or above this temperature, direct contact can cause rapid skin burns, so these materials are treated with extra precautions—cooling, special tools, and heat-resistant PPE—to prevent injuries. The other concepts don’t describe temperature: an explosive involves rapid energy release, an inhabited building relates to occupancy, and leaching is a chemical process of dissolving substances in liquid. So, hot material best fits a material having a temperature exceeding 57°C.
