Foam suppression systems are used at flammable chemical fires or fuel fires which can not be extinguished by water. Foam used within foam suppression systems covers the area and prevents connection between fire and air. Foam, water and air are the main components of foam suppression systems. Foam is formed by expansion of the foam solution with water and air under pressure and discharges into the enclosure through nozzles. Foam used within foam suppression systems also creates cooling effect and prevents evaporation on the burning surface.
