What is the distinction of a combustible liquid?

A combustible liquid is defined as a liquid that has a flash point at or above 100 degrees Fahrenheit. The flash point is the lowest temperature at which a liquid can vaporize to form an ignitable mixture in air. This means that combustible liquids can ignite but require a higher temperature to do so compared to flammable liquids, which have a flash point below 100 degrees Fahrenheit.

Understanding this distinction is crucial when it comes to handling, storing, and transporting chemicals safely, as it dictates the precautions that need to be taken to prevent fire hazards. Knowing the flash points helps in evaluating the risk associated with different liquids, ensuring proper safety measures are implemented in various environments such as laboratories or industrial settings.

The other options misrepresent the characteristics of combustible liquids; they either focus on different flash point ranges or incorrect storage requirements, which do not align with the official definitions used in safety regulations.
