What defines Class 3: Flammable Liquids?

Class 3: Flammable Liquids is specifically defined by the characteristic of having a specific flash point, which is the lowest temperature at which the vapors of a flammable liquid can ignite when an ignition source is present. This definition is crucial for classifying and handling these materials safely.

The importance of defining flammable liquids by their flash point lies in the fact that it provides measurable criteria to assess the hazards associated with these materials. Different flammable liquids may have varying flash points, which dictate their potential risk in different environments and scenarios. For example, substances with lower flash points are considered more hazardous because they can ignite at lower temperatures.

Understanding flash points is vital in ensuring appropriate transport, storage, and response measures for these hazardous materials, making it an essential element of safety protocols in handling flammable liquids.
