AFFF (Aqueous Film Forming Foam): A foam concentrate containing flour chemical surfactants that control the physical properties of water enabling it to float and spread across the surface of the hydrocarbon
Alcohol Resistant (AR): A foam concentrate for use on polar solvents in addition to hydrocarbons.
Alcohol Resistant Aqueous Film-Forming Foam (AR- AFFF): AFFF that is suitable for use on polar solvents in addition to hydrocarbons.
Alcohol Resistant Film-Forming Fluor protein (AR FFFP): FFFP that is suitable for use on polar solvents as well as hydrocarbons.
Fluor protein (FP): A natural protein-based foam concentrate containing fluorocarbon surfactants that provide a fuel shedding property to the finished foam. Extensively u s e d in oil a n d petro c he m ictal Indus tries. (See oleo phobic).
Class A Fire: A fire in materials such as wood and paper where the cooling effect of water or Class A foam is of paramount importance in extinguishing the fire. Fires that occur in ordinary combustible materials, i.e. wood, paper, rubber, and certain plastics, etc. (NFPA 10 definition).
Class a Foam: Foam specially formulated for use on Class A fires. Essentially wetting agents that reduce the surface tension of water and allow it to soak into combustible materials easier than plain water.
Class B Fire: A fire involving a flammable liquid where a blanket or smothering effect is of first importance in extinguishment (CEN definition). Fires which occur in flammable liquids, oils, tars, lacquers, etc. And flammable gases (NFPA 10 definition). Fires in flammable and combustible liquids, gases, and greases (UL 162 definition).
Class B Foam: Foam formulated to be used on fires or spills of flammable and combustible liquids.
Class C Fire – USA: A fire in “live” electrical equipment where the use of non-conducting fire suppression agents is of prime importance.
Class C Fire – EUROPE: Fires involving gases or liquefied gases in the form of in the form of a liquid spillage, or a liquid or gas leak (CEN definition).
Class D Fire: A fire involving a metal such as magnesium, sodium, lithium, etc. (CEN definition). Fires that occur in metals such as magnesium, zirconium, lithium, etc. (NFPA 10 definition).
Class E Fire – Europe: A fire in ‘live’ electrical equipment where the use of non-conducting fire suppression agents is of prime importance.
Aqueous Film-Forming Foam (AFFF): Pronounced AFFF. A synthetic foam concentrate containing detergent and fluorocarbon surfactant that forms a foam capable of producing a vapor-suppressing aqueous film on the surface of some hydrocarbon fuels. Provides rapid flame knockdown for aircraft crash fires. Developed in the 1960s, by the Naval Research Laboratory (NRL) in association with the 3M Company.
AFFF -Polar (AR-AFFF): An AFFF that contains a polysaccharide material that forms a polymeric layer or film only on polar solvents to separate and protect the finished foam.
Film-Forming: A foam concentrate containing fluorocarbon surfactants that has a spreading coefficient greater than zero and so forms a foam capable of producing a vapor- suppressing aqueous film on the surface of most hydrocarbon fuels.
Film-Forming Fluor protein (FFFP): Pronounced Triple F. A natural protein-based foam concentrate containing additional fluorocarbon surfactants that forms a foam capable of producing a vapor suppressing aqueous film on the surface of some hydrocarbon fuels .
