1% Aqueous Film Forming Foam Freeze Protected Concentrate

Phos-Chek® 1% AFFF Freeze Protected foam concentrate is proportioned at 1% concentration in both fresh and sea water and is effective on hydrocarbon fuels like gasoline, heptane, crude oil, and other fuels that are not soluble in water. Our 1% AFFF concentrate is ideal for use on fixed foam systems in space constrained low temperature (-7F or -22C) areas and is compatible with standard proportioning and foam making devices. Because manual firefighting operations are labor intensive, 1% freeze protected concentrate is often the choice in emergency response requiring less time and space at the scene and optimizing the firefighters’ time to fight the fire.

Phos-Chek 1% AFFF Freeze Protected may be used with:

  • Low expansion foam equipment (nozzle, monitors, foam chambers, etc.)
  • Non-aspirating devices (water spray nozzles and standard sprinklers)
  • Medium expansion foam devices to fight fires involving Class B hydrocarbon fuel fires (crude oil, aviation fuels, diesel, etc.)
