Kerosene flashpoint

Class II liquids with flashpoints at or above 100°F but below 140°F. Examples of Class II flammable liquids are kerosene and camphor oil (NFPA Diamond 2). 

The flammability of mists is much less well known than that of va-pour/air and dust/air mixtures. Flammable mists are similar in many ways to dusts and are produced when fine droplets of a flammable liquid are dispersed in air. This can occur when involatile flammable liquids such as xylene or kerosene are transferred rapidly into a vessel. Rapid pumping and splashing into the vessel, particularly if it is empty, causes fine droplets to be dispersed in air and can produce a mist, which can be flammable even at temperatures 100-200°C below the flashpoint of the parent liquid. 

Various common liquids have different flashpoints, so different containers can be used for storage at jobsites. For example, common diesel fuel grades have flash points below 140°F. This would make them flammable liquids and they must be stored in safety cans or Department of Transportation (DOT) approved containers. Some grades of kerosene have flash points greater than 140°F and do not need to be stored in safety cans or DOT approved containers.
