WILLIAMS  Foam Concentrate delivers exceptional firefighting performance, continuing the renowned heritage of WILLIAMS foams. Foam Concentrate is a 3%x3% Alcohol Resistant Non-Fluorinated Foam Concentrate that provides excellent fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for forceful or gentle firefighting applications at 3% solution on hydrocarbon fuels and gentle firefighting applications at 3% solution on polar solvent fuels.
 
WILLIAMS  foam solution utilizes three suppression mechanisms intended for rapid fire knockdown and superior burnback resistance:
The foam blanket has extended drain times to help block oxygen to the fuel and suppress fuel vapor
On polar solvent fires, liquid drains from the foam blanket and forms a polymeric membrane which protects the foam from destruction by the polar fuel, suppresses vapors, and seals the fuel surface
The water content of the foam solution produces a cooling effect for additional fire suppression
 
Approvals, Listings, and Standards
Designed, tested and demonstrated to provide excellent control and suppression of large hydrocarbon tank fires per Williams Fire & Hazard Control’s 42’ Tank Fire Type III Plunge Protocol
Designed in accordance with NFPA Standard 11 for Low and Medium Expansion Foams
UL 162 listed as an alcohol resistant synthetic fluorine free foam (AR-SFFF) concentrate for use on hydrocarbon and polar solvent fuel fires
Passes UL 162 type III test protocol on hydrocarbons at the same 0.10 gpm/ft2 (4.1 Lpm/m2) design application rate as traditional AR-AFFF products with similar control times
Recommended minimum application rate of 0.16 gpm/ft2 (6.5 Lpm/m2) for fuel in-depth tank fires up to 150 feet (45.7 m) in diameter; for larger tank sizes please contact the WILLIAMS FIRE & HAZARD CONTROL® team directly for further guidance
Recommended minimum application rate of 0.10 gpm/ft2 (4.1 Lpm/m2) for spill fire applications
Superior drain times to high-quality AR-AFFFs, with a longer lasting foam blanket for better burnback resistance and post-fire suppression
Dry chemical agent compatible
