    THUNDERSTORM W813A-FP 1x3 Freeze-Protected AR-AFFF (Alcohol Resistant Aqueous Film-Forming Foam) Concentrate from Williams Fire & Hazard Control delivers exceptional firefighting performance, continuing the renowned heritage of THUNDERSTORM products. THUNDERSTORM W813A-FP combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydrocarbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 1% solution for hydrocarbon fuels and at 3% solution for polar solvent fuels in fresh, salt, or hard water.

    Approvals, Listings, and Standards

    THUNDERSTORM W813A-FP 1x3 Freeze-Protected AR-AFFF Concentrate is designed in accordance with National Fire Protection Association (NFPA) Standard 11 for Low-, Medium-, and High-Expansion Foam. The concentrate is approved, listed, qualified under, or meets the requirements of the following specifications and standards:

    • UL Standard 162, Foam Liquid Concentrates 
    • ULC S564, Category 2 Foam Liquid Concentrates

    The THUNDERSTORM W813A-FP formulation has been successfully evaluated in accordance with the Williams Fire & Hazard Control Plunging Test protocol.

    Application

    THUNDERSTORM W813A-FP 1x3 Freeze-Protected AR-AFFF 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 also has excellent wetting properties that can effectively combat Class A fires.  To provide even greater fire protection capability, THUNDERSTORM W813A-FP foam solution may be applied simultaneously with WILLIAMS FIRE & HAZARD CONTROL PKW dry chemical for a twin-agent system. When using twin-agent application on polar solvent fuels, care must be taken with the velocity of the dry chemical discharge to minimize submergence of the polymeric membrane below the fuel surface. 

    THUNDERSTORM W813A-FP Concentrate can be ideal for fixed, semi-fixed, and emergency response firefighting applications such as:

    • Flammable liquid in depth and spill fires 
    • Fuel or chemical storage tanks 
    • Industrial chemical and petroleum processing facilities 
    • Truck/rail loading and unloading facilities 
    • Mobile equipment
