Foam fire extinguishers
Foam extinguishants are most effective on Class B fires although it can also be used on Class A fires. A fast flowing film forms a gastight blanket on liquid surfaces giving rapid fire control and burnback security. It is stable on fuels with proportions of polar additives like alcohol and other ones. It is also invaluable in preventing serious Class B fires by application to spilled flammable liquids before ignition.
