What is the flash point of a combustible liquid?

The flash point of a combustible liquid is defined as the lowest temperature at which the liquid produces enough vapor to form an ignitable mixture with air. When the temperature reaches this point, the liquid can emit vapors that can ignite momentarily when exposed to an ignition source, such as an open flame or spark. This characteristic is crucial in assessing fire hazards associated with different liquids, as it indicates the conditions under which a liquid can pose a risk of combustion.

Understanding the flash point is particularly important for safety in handling and storing combustible liquids. By knowing the flash point, safety personnel can implement appropriate measures, such as ventilation or temperature control, to minimize fire risks in environments where these liquids are used or stored.
