By definition, a flammable liquid has a flash point below which temperature?

A flammable liquid is defined as a liquid that has a flash point of less than 100°F (37.8°C). The flash point is the lowest temperature at which a liquid can form an ignitable mixture in air.

When a flammable liquid is at or above this temperature, it can ignite if there is an ignition source nearby. The significance of this threshold is critical in hazardous materials management, as it helps determine safety protocols for storing, handling, and using flammable substances.

This classification plays a crucial role in determining not only storage and handling requirements but also in assessing the potential risks associated with spills or exposures, enabling responders to develop appropriate plans and strategies for incident management. The other temperature options are above the defined limit for flammable liquids, making them unsuitable for this classification.
