WebJan 20, 2024 · Gasoline is a flammable liquid most people are familiar with. The flashpoint of gasoline is approximately -36 degrees Fahrenheit, which is lower than the usual working temperatures we use gasoline in. It’s a hazard to smoke at a gas station because the temperature is well above the -36 degree flashpoint. WebThe legal description of flammable is used for all liquids with a flash point less than 100 deg F (37.8 C), and the term combustible is used for liquids with a flash point in excess of 100 deg F (37.8 C).
