Class B Foam Concentrates are ideal for suppressing fires involving petroleum-based products, LNG, rubber, and flammable and combustible liquids; such as diesel fuel, crude oil gasoline and ethanol.
ANSULITE® Aqueous Film-Forming Foam (AFFF) Concentrates can be applied through a wide variety of delivery systems which provides extreme versatility. The foam is an ideal fire suppression choice for airports, refineries, manufacturing plants, municipal fire departments, and other operations involving the transportation, processing, or handling of flammable liquids. It is available as 1%, 3%, and 6% concentrates or as 1% and 3% freeze-protected concentrates.
As with other Class B Foam Concentrates, ANSULITE AFFF extinguishes fires of flammable gases, liquids, greases, and similar materials by excluding oxygen and inhibiting the release of combustible vapors. The combustion of these liquids and gases involves rapid vapor-phase oxidation of the fuel and subsequent involvement of more fuel due to radiant heat feedback.
