Foam System
Certain high hazards cannot be controlled or extinguished with ordinary sprinkler systems, but with water spray systems (also say deluge systems). They are typical used in high hazard applications where the need to discharge large quantities of water on the areas of fire.
What is firefighting foam?
Simply stated, firefighting foam is a stable mass of small, air-filled bubbles with a lower density than oil, gasoline, or water. Foam is made up of three ingredients…water, a foam concentrate, and air. Water is mixed with a foam concentrate (proportioned) to form a foam solution. This solution is then mixed with air (aspirated) to produce a foam which readily flows over fuel surfaces.
How do foam agents work?
Firefighting foam agents suppress fire by
separating the fuel from the air (oxygen).
Depending upon the type of foam agent, this is done in several ways:
Foam blankets the fuel surface, smotheringthe fire and separating the flames from the
fuel surface. The fuel is cooled by the water content of the foam.
The foam blanket suppresses the release of flammable vapors that can mix with air.
