HIGH EXPANSION FOAM CONCENTRATE
DESCRIPTION:
This is a proven-effective, concentrate liquid designed to form a dense foam suitable to extinguish all types of CLASS A and some CLASS B FIRES.
High expansion foam extinguishes by a combination of 3 properties. Firstly, the dense foam blankets the combustible substrate to prevent air (oxygen) from supporting combustion. Secondly, as bubbles collapse they release their water and become vaporized, providing a cooling action that slows down the rate of combustion. Thirdly, water released from the foam contains wetting agents which facilitate penetration into the substrate and increase the rate of extinguishment.
DIRECTIONS:
Use this fire-fighting foam in all types of low, medium, and high expansion equipment. It can be used successfully at a dilution of 1:32 with water.
