Water Additive

To increase the effectiveness of water based fire extinguishers a detergent based additive can be introduced which breaks the surface tension of the water and allows it to penetrate Class A materials faster and more efficiently. This increases the rating of the water extinguisher, enabling it to combat larger fires.

Wet Chemical

Wet chemical extinguishant combats a fire by forming a soapy foam blanket over the burning oil which starves the fire of oxygen while lowering the temperature of the oil below that of ignition. Wet chemical extinguishers are designed for use on Class F (deep fat fryer) fires but usually carry an additional Class A rating which can add to the extinguisher provision of a building.
