T-STORM WTS306B 3x6 AR-AFFF (Alcohol Resistant Aqueous Film-Forming Foam) Concentrate from WILLIAMS FIRE & HAZARD CONTROL combines fluoro- and hydrocarbon-surfactant technologies to provide superior fire and vapor suppression for Class B, polar solvent and hydro-carbon fuel fires. This synthetic foam concentrate is intended for firefighting applications at 3% solution for hydrocarbon fuels and at 6% solution for polar solvent fuels in fresh, salt, or hard water.

Approvals, Listings, and Standards

T-STORM WTS306B 3x6 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


T-STORM WTS306B 3x6 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.

To provide even greater fire protection capability, T-STORM WTS306B foam solution may be applied simultaneously with WILLIAMS FIRE & HAZARD CONTROL PKW dry chemical for a twin-agent system. When using a twin-agent application on polar solvent fuels, take care with the velocity of the dry chemical discharge to minimize submergence of the polymeric membrane below the fuel surface.

T-STORM WTS306B Concentrate can be ideal for fixed, semi-fixed, and emergency response firefighting applications such as: 

  • Fuel or chemical storage tanks 
  • Industrial chemical and petroleum processing facilities 
  • Truck/rail loading and unloading facilities 
  • Flammable liquid containment areas 
  • Mobile equipment
