Question 1021 Deck General

The correct answer is B) 80°F (27°C). Combustible liquids are defined as liquids with a flash point above 80°F (27°C), according to U.S. Coast Guard regulations. This means that the liquid must be heated to at least 80°F (27°C) before it will produce enough vapor to ignite when exposed to an ignition source. The other answer choices are incorrect because: A) 40°F (4°C) is the definition for flammable liquids, not combustible liquids. C) 110°F (43°C) and D) 150°F (66°C) are higher flash points than the regulatory definition for combustible liquids.
