Foam fire extinguishers are portable fire-fighting devices that operate by pressurizing and discharging a mixture of water and foam concentrate, proving especially effective against Class A and B fires. They extinguish fires through both cooling and smothering mechanisms. These systems create a film over flammable liquid surfaces, cutting off contact with oxygen and preventing vaporization. Historical Background The history of foam fire extinguishing systems dates back to the early 20th century.
