Flash Point of Common Fuels

The flash point of a fuel is the lowest temperature at which it can vaporize to form an ignitable mixture in the air. It is a crucial safety parameter as it indicates the potential fire hazard associated with the fuel.

The following table provides a curated list of flash point values for common fuels at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
