What is in fire extinguisher foam?
For years, foam has been used as a fire-extinguishing medium for flammable and combustible liquids. FOAM: A fire fighting foam is simply a stable mass of small air-filled bubbles, which have a lower density than oil, gasoline or water. Foam is made up of three ingredients – water, foam concentrate and air.
What is foam used for in a fire?
Firefighting foam is a foam used for fire suppression. Its role is to cool the fire and to coat the fuel, preventing its contact with oxygen, resulting in suppression of the combustion. Fire-fighting foam was invented by the Russian engineer and chemist Aleksandr Loran in 1902.
Is AFFF foam hazardous?
Is AFFF Toxic? AFFF is toxic, especially if it contains PFOS and PFOA. These PFAS are present in small amounts in the blood of most people in the United States, according to the U.S. Department of Veteran’s Affairs and the EPA. For most people, they don’t pose a threat in small amounts.
Does Afff expire?
When stored in the packaging supplied (polyethylene drums or pails) or in equipment recommended by the manufacturer as part of the foam system and within the temperature limits specified, the shelf life of ANSULITE ARC 3% or 6% AR-AFFF Concentrate is about 20-25 years.
What is the shelf life of Class A foam?
20-25 years
Does Class A foam expire?
The effective life of CLASS A PLUS foam concentrate can be maximized through optimal storage conditions and proper handling. CHEMGUARD concentrates have demonstrated effective firefighting performance with contents stored in the original package under proper conditions for more than 10 years.
What color liquid is AFFF concentrate?

What is the difference between AFFF and FFFP?
An AFFF Foam fire extinguisher is effective on Class A and Class B fires. FFFP is an alcohol resistant agent making it effective on Class B fires involving alcohols, polar solvents, hydrocarbons, and combinations of these. It can be applied to Class B liquid spills to prevent ignition.
