What is a combustible liquid?

A combustible liquid is defined as a liquid that has a flash point at or above 100°F but below 200°F. This range indicates that while the liquid can ignite and burn, it requires a higher level of heat to reach its flash point compared to flammable liquids, which are defined as having a flash point below 100°F.

Understanding flash point is crucial in aviation and safety practices, as it helps determine the handling and storage requirements for various liquids used in aircraft maintenance and operations. Liquids in the combustible range are significant because they can pose a fire hazard under specific conditions, especially in environments where they may be exposed to ignition sources. Hence, knowing that a liquid falls into this category is vital for ensuring safety protocols are followed properly in aviation settings.
