A flammable liquid is a liquid which can be easily ignited in air at ambient temperatures, i.e. it has a flash point at or below nominal threshold temperatures defined by a number of national and international standards organisations.
Categorization
Both OSHA and GHS further divide flammable liquids into 4 categories: • Category I flammable liquids are those with boiling points ≤ and flash points 35 °C/95 °F and flash points and ≤ • Category IV flammable liquids are those with flash points > 60 °C/140 °F and ≤ 93 °C/199.4 °F These categorizations are dependent upon a set altitude and atmospheric pressure, as both boiling point and flash point change with changes in pressure. == Labeling ==
Labeling
Both GHS and OSHA require the labeling of flammable liquids, on containers and safety data sheets, as follows: == See also ==
