What kind of liquid has a flash point at or above 37.8°C (100°F)?

A liquid with a flash point at or above 37.8°C (100°F) is classified as a combustible liquid. This classification is significant in fire safety and prevention because it indicates that the liquid can ignite and burn, but requires a higher temperature than flammable liquids to do so.

Flammable liquids, on the other hand, have a flash point below 37.8°C (100°F), making them more prone to ignition at lower temperatures. Inert liquids do not support combustion or are chemically stable and not reactive in a way that would produce flames. Noncombustible liquids do not ignite or produce flames under standard conditions, distinguishing them from combustible and flammable categories.

Understanding these classifications is crucial for fire investigators and safety professionals when assessing fire risks, handling materials, and developing safety protocols in environments where these types of liquids are present.
