Hazard vs. Flash Points

The flash point of a chemical indicates how easy it may ignite and burn.

The flash point of a chemical is the lowest temperature where it will evaporate enough fluid to form a combustible concentration of gas. The flash point is an indication of how easy a chemical may burn.

Materials with higher flash points are less flammable or hazardous than chemicals with lower flash points.

Hazard vs. Flash Points
HazardFlash Point
Very Low Hazard  > 200oF
(93oC)
Moderate Low Hazard 150oF to 200oF
(66oC to 93oC)
High to Moderate Hazard 100oF to 150oF
(38oC to 66oC)
Extreme to High Hazard 0oF to 100oF
(-18oC to 38oC)
Extreme Hazard < 0oF
(-18oC)

An open flame is not always necessary to ignite a gas. A hot surface - like a heating element or warm machine - will do for chemicals with more than high hazard.

See Autoignition temperature and flash point of different hydrocarbons and Flash Point - Fuels for measured values of flash point.

The Flash Point is not the same as the Auto-Ignition Temperature. The Auto-Ignition Temperature is the minimum temperature required to ignite a gas or vapor in air without a spark or flame present.
