|
|
Industrial Fire and Hazard Control is proud to introduce the Williams WNF33A foam concentrate into the African market. The WNF33A non-fluorinated foam delivers exceptional firefighting performance, continuing the renowned heritage of Williams Fire and Hazard Control foams. WNF33A is a 3%x3% alcohol resistant non-fluorinated foam concentrate that provides excellent fire and vapour 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 for gentle firefighting applications at 3% solution on polar solvent fuels.
Approvals, listings and standards
Application
Williams 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.
Williams 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:
