In The Know: Flashpoints

Posted by TechStar on Jun 22, 2023 9:26:00 AM

This month we explore the concept of flashpoints and their significance in fire safety. A flashpoint refers to the temperature at which a flammable substance releases sufficient vapor to ignite when exposed to an external source of ignition, such as a spark. It serves as a crucial factor in determining the fire hazard potential of various liquids.


Flammable materials, in their normal state, do not emit enough gas or vapor to initiate a fire. Only when heated to their specific flashpoints do they generate the necessary amount of vapor to sustain combustion.

Below this critical temperature, the liquid fails to produce adequate vapor for ignition, rendering it non-flammable.

To gain insights into the flashpoints of different substances, we can refer to the National Fire Protection Agency's (NFPA) authoritative document, NFPA-325M: Fire Hazard Properties of Flammable Liquids, Gases, and Volatile Solvents. This resource provides a comprehensive listing of flashpoints for numerous common substances, serving as a valuable reference for individuals seeking to enhance their understanding of fire safety. For further details, visit the official NFPA website at NFPA.

By familiarizing ourselves with the flashpoints of various materials, we can make informed decisions to mitigate fire risks effectively. Identifying the flashpoint of a substance enables us to implement appropriate safety measures, ensuring that ignition sources are kept well away from potentially hazardous situations.
