New non-fluorinated Thunderstorm WNF33A foam concentrate advances fire protection for flammable liquid storage tanks
Williams Fire and Hazard Control has announced the launch of Thunderstorm WNF33A 3%x3% non-fluorinated foam concentrate, the newest addition to the renowned Williams Fire and Hazard Control fire fighting foam portfolio and which is now available through Industrial Fire and Hazard Control in South Africa. Fuel in-depth fires and sunken roof hazards can occur at flammable liquid storage facilities, oil and gas tank farms, refineries and petrochemical processing operations. Historically, non-fluorinated foams have been challenged to deliver the performance of a traditional alcohol-resistant aqueous film-forming foam (AR-AFFF) for Class B fire fighting on these types of hazards. The new Thunderstorm WNF33A Foam Concentrate provides excellent fire and vapor suppression for hydrocarbon fuels, such as gasolines and diesel, as well as for polar-solvent fuels, such as alcohols and ketones.
Application Thunderstorm WNF33A 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.
Thunderstorm WNF33A 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
Backed by the industry leader Continuing the renowned, 70-year heritage of Thunderstorm foams from the Williams Fire and Hazard Control product portfolio as well as other Johnson Controls fire protection products and solutions, Thunderstorm WNF33A Foam Concentrate delivers the fire fighting performance needed to respond with confidence to today’s most challenging oil, gas, chemical and industrial fires.
Thunderstorm WNF33A Foam Concentrate is a GreenScreen Certified Silver formulation. As a non-fluorinated foam concentrate, it doesn’t have any intentionally added PFAS chemistry, is produced in equipment that has not handled PFAS chemistry and inherently complies with Directives (EU) 2017/1000 on PFOA and 2019/1021 (EU POPs directive).
