All flashing liquids are combustible.

All flashing liquids are combustible.

• A. False
• B. True
• C. Sometimes
• D. Never

Answer: (A)

The concept being tested is how flash point relates to flammability. The flash point is the temperature at which a liquid’s vapors can ignite in air with an ignition source. Just because a liquid can flash under certain conditions doesn’t automatically mean it’s classified as combustible in every regulatory sense, and not all liquids that can flash will behave as a sustained, steady burn in normal conditions. Because of this nuance and the way different standards define flammable versus combustible, the blanket statement that all flashing liquids are combustible isn’t universally true.
