THUNDERSTORM W813A 1×3 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 Concentrate combines fluoro- and hydrocarbon-surfactant technology to provide superior 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 1% solution on hydrocarbon fuels and gentle firefighting applications at 3% solution on polar solvent fuels in fresh, salt, or hard water.
The environmentally-mindful THUNDERSTORM W813A 1x3 AR-AFFF Concentrate formulation contains short-chain, C-6 fluorochemicals manufactured using a telomer-based process. The telomer process produces no PFOS, and these C-6 materials do not breakdown to yield PFOA. The fluorochemicals used in the concentrate meet the goals of the U.S. Environmental Protection Agency 2010/15 PFOA Stewardship Program.
THUNDERSTORM W813A 1×3 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:
The THUNDERSTORM W813A formulation has been successfully evaluated in accordance with the Williams Fire & Hazard
Control Plunging Test protocol.
In addition, THUNDERSTORM W813A qualifies as a C-6 Purity Compliant foam under the requirements of the Queensland Department of Environmental and Heritage Protection’s Policy on the Environmental Management of Firefighting Foam. Click here for details.
THUNDERSTORM W813A 1x3 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; 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 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 Concentrate can be ideal for emergency response and semi-fixed firefighting applications such as:
