Liquids capable of burning and sustaining combustion from an open fire source after removing the ignition source are classified as flammable liquids (FL) and flammable liquids (FL).

Characteristics of flammable and combustible liquids

Flammable and flammable liquids differ in terms of their flash point. Flash point is the lowest temperature of a liquid at which vapors above the surface of the liquid can ignite from an open fire. Flammable liquids have a flash point not higher than 61 ° C, flammable liquids - above 61 ° C.

Types of flammable and combustible liquids

Flammable liquids are of three categories: especially dangerous (first category), constantly dangerous (second category), and dangerous at elevated air temperatures (third category). The flash point of especially dangerous flammable liquids is -13оС. A characteristic feature of especially hazardous flammable liquids is the need for certain conditions for their transportation, since if the storage vessel is not sealed, liquid vapors can quickly spread and ignite at a distance from the vessel. These liquids include acetone, some types of gasoline, ether, petroleum ether, diethyl ether, hexane, isopentane, cyclohexane.

Flammable liquids of the second category have a flash point from -13 to + 23оС. Such liquids have the ability to ignite at room temperature when their vapors are combined with air. These are liquids such as ethyl alcohol, benzene, methyl acetate, ethyl acetate, ethylbenzene, octane, toluene, isooctane, lower alcohols, dioxolanes and dioxanes.

Flammable liquids of the third category are flammable liquids with a flash point from +23 to + 60 ° C. Such liquids will only ignite if there is a source of fire in the immediate vicinity. These include the following liquids: turpentine, solvent, white alcohol, xylene, cyclohexanone, amyl acetate, butyl acetate, chlorobenzene.

Flammable liquids have the property of self-combustion at a flash point above 61 ° C. Flammable liquids include fuel oil, oils (vaseline, castor), diesel fuel, glycerin, ethylene glycol, hexyl alcohol, hexadecane, aniline. Such liquids can be stored in open containers and reservoirs (for example, in barrels), including in the open air. When working with flammable and flammable liquids, remember the need to comply with fire safety rules for storage, transportation and use.
