The international pictogram for flammable chemicals. Flammable placard. 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.
The vapor pressure of a liquid, which varies with its temperature, is a measure of how much the vapor of the liquid tends to concentrate in the surrounding atmosphere as the liquid evaporates. [30] Vapor pressure is a major determinant of the flash point and flame point, with higher vapor pressures leading to lower flash points and higher ...
