WILLIAMS WNF33A 3x3
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
  • Successfully evaluated in accordance with the WILLIAMS FIRE & HAZARD CONTROL® Plunging Test Protocol

WILLIAMS WNF33A 3x3

  • WILLIAMS  Foam Concentrate is intended for use on both types of Class B fires: hydrocarbon fuels with low water solubility, such as crude oils, gasolines, diesel fuels, and aviation fuels; and polar solvent fuels with appreciable water solubility, such as methyl and ethyl alcohol, acetone, and methyl ethyl ketone. The concentrate has excellent wetting properties that can effectively combat Class A fires. It may also be used in conjunction with dry chemical agents to provide even greater fire suppression performance.

     

    WILLIAMS  Foam Concentrate is well-suited for use in municipal and industrial response for spills and fuel in-depth fires. It may be applied with either an aspirating or non-aspirating nozzle on both Type III applications as well as foam systems with Type II discharge devices. 

     

    Examples of these applications include:

    • Flammable liquid in-depth and spill fires
    • Fuel and chemical storage tanks
    • Industrial chemical and petroleum processing facilities
    • Truck/rail loading and unloading facilities
    • Flammable liquid containment areas
