Flash Point of Common Alcohols
The flash point of a substance is the lowest temperature at which it can vaporize to form an ignitable mixture in air. Generally, alcohols have relatively low flash points compared to some other flammable liquids.
The following table provides a curated list of flash point values for common alcohols at 1 atmospheric (atm) pressure. (1 atm = 101,325 Pa)
