Quickly and effectively extinguishes structural, wildland, and industrial Class A type fires. By increasing the ability of water to penetrate deep-seated fuels, Phos-Chek WD 881 shortens the time firefighters are exposed to blazes, lessens property damage, and reduces total systems costs. Plus, Phos-Chek Class A foam concentrate does not have a flash point. Phos-Chek WD 881 meets three critical industry qualifications including approval by the USDA Forest Service for all methods of application including use in fixed tank helicopters, UL listing as a wetting agent at a low 0.25% use rate, and the absence of any EPA listed hazardous materials. Phos-Chek WD 881 is also readily biodegradable to ensure environmental safety.
