The World’s Most Comprehensive Portfolio of Fire Safety Solutions


Perimeter Solutions’ PHOS-CHEK and FIRE-TROL fire retardants help slow, stop and prevent the start of wildfires by making wildland fuels non-flammable. Aerial retardants can be applied by air – via fixed or rotor wing aircraft. They are also applied on the ground using standard engines or one of Perimeter Solutions’ dedicated ground-applied retardant units. All products have a high level of fire retardant effectiveness, with differences in visibility, viscosity, adherence to vegetation and persistence through weathering.
