How is a combustible liquid defined?

A combustible liquid is specifically defined based on its flash point, which is the lowest temperature at which the vapor of a liquid can ignite in air. The correct definition indicates that a combustible liquid has a flash point between 100°F and 141°F. This classification is essential because it helps responders determine the appropriate safety measures and handling procedures needed when dealing with such materials during HazMat incidents.

When a liquid has a flash point below 100°F, it is classified as a flammable liquid, which poses different hazards and requires different precautions. Similarly, a liquid with a flash point above 141°F is considered a non-combustible liquid and does not present the same ignition risks. Therefore, understanding the classification of combustible liquids and their specific range is crucial for assessing risks and implementing safety protocols.
