A liquid with a flash point greater than or equal to 140 degrees F is called which?

• A. Flammable
• B. Nonflammable
• C. Combustible
• D. Volatile

Answer: (C)

A liquid’s flash point is the lowest temperature at which its vapors can ignite in air. Safety standards often use a 60°C (140°F) cutoff to separate flammable from combustible liquids: below 140°F it’s considered flammable, at or above 140°F it’s combustible. So, if a liquid has a flash point of 140°F or higher, it falls into the combustible category. This classification guides how it’s stored and handled, including fire protection requirements. The other terms aren’t the official category here: a lower flash point would indicate flammable, a much higher one could be described as nonflammable, and volatile describes how readily a liquid evaporates rather than its ignition category.
