What is the flash point range for combustible liquids as stated?

• A. Flash point between 0 and 20 degrees.
• B. Flash point between 141 and 200 degrees.
• C. Flash point below 0.
• D. Flash point above 200 degrees.

Answer: (C)

Flash point is the lowest temperature at which a liquid’s vapor can ignite in air. In hazmat practice, liquids with a flash point below 100°F are considered flammable, while those with a flash point at or above 100°F are considered combustible. That means combustible liquids must have a flash point well above 100°F, which corresponds to ranges like 141–200°F or above 200°F. A range of 0–20°F is below the 100°F threshold and would describe a flammable liquid, not a combustible one. A flash point below zero isn’t a realistic standard category for liquids in this context. So the proper understanding is that combustible liquids have flash points above 100°F, not in the lower or negative ranges.
