How is 'flammable liquids' defined?

The definition of 'flammable liquids' is specifically based on their flash point, which is the lowest temperature at which they can vaporize to form an ignitable mixture in air. A flash point below 100 degrees Fahrenheit indicates that the liquid can easily produce enough vapor to ignite at relatively low temperatures, making it highly flammable and posing significant safety risks in a facility.

Understanding this definition is crucial for safety protocols, as it helps in identifying which liquids require special handling, storage, and transport measures to mitigate the risks associated with fires and explosions. In contrast, the other options do not accurately characterize flammable liquids in a way that aligns with established safety standards. For instance, not all liquids that can cause explosions are categorized solely based on their flammability, and the terms regarding storage and the nature of flames do not directly relate to the fundamental definition of flammable liquids.
