Which term describes a substance that catches fire easily with a flash point less than 100F?

• A. Flammable Liquid
• B. Corrosive
• C. Exposure Routes
• D. Health Hazard

Answer: (A)

A substance that catches fire easily with a flash point below 100°F is classified as a flammable liquid. The flash point is the lowest temperature at which a liquid’s vapors can form an ignitable mixture with air under specific test conditions. When that temperature is under 100°F, the liquid can ignite more readily, so safety labeling and handling guidelines designate it as flammable. The other terms describe different properties: corrosive means it can damage skin or materials, exposure routes refer to how the substance can enter the body, and health hazard covers a broad range of potential adverse health effects, not specifically flammability.
