What is AR-AFFF foam used for?
Class B Foam Agents 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.
What is the difference between AFFF and AR-AFFF?
Using plain AFFF concentrate as a base material, a high molecular weight polymer is added during the manufacturing process. When AR-AFFF is used on a polar solvent fuel fire, the polar solvent fuel tries to absorb water from the foam blanket.
How does AR-AFFF foam work?
AR-FFFP foams act as conventional FFFPs on hydrocarbon fuels forming an aqueous film on the surface of the hydrocarbon fuel. When used on polar solvents (or water-miscible fuels), the polysaccharide polymer forms a tough membrane, which separates the foam from the fuel and prevents the destruction of the foam blanket.
What is AR-AFFF foam?
CHEMGUARD Alcohol Resistant Aqueous Film-Forming Foam Concentrates (AR-AFFF) combine fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. The foam blanket blocks oxygen supply to the fuel. …
What does AR-AFFF stand for?
Aqueous film forming foam (AFFF, or alcohol resistant AR-AFFF) is a highly effective foam used for fighting high-hazard flammable liquid fires. AFFF is usually created by combining foaming agents with fluorinated surfactants.
Does AR-AFFF contain Pfas?
The vast majority of Class B firefighting foam that is currently in stock or service in the United States is AFFF or AR-AFFF. All AFFF products contain PFAS.
Is AFFF corrosive?
Ship decks have aqueous firefighting foam (AFFF) stations that are used for fire fighting. The foam is, however, corrosive and can make holes in the decks. Right beneath those holes tends to be important rooms or tanks. They certainly wouldn’t want something dripping onto a person or equipment.
What type of fire is AFFF used on?
flammable liquid fires
Aqueous Film Forming Foam (AFFF) is a fire suppressant used to extinguish flammable liquid fires such as fuel fires. AFFF is often used in shipboard and shore facility fire suppression systems, fire fighting vehicles, and at fire training facilities.
Does AR-AFFF contain PFAS?
What color liquid is AFFF?
