Permanent pressure - Standard
The specially designed nozzle provides excellent cooling and penetration effects on Class A fires and additional sealing effects on Class B fires. The nozzle is also safety tested against accidental use on live electrical equipment up to 1.000 Volts. Contrary to dry powder extinguishers which are also suitable for Class A and B fires foam extinguishers only leave minimal residue after operation. The foam extinguishant is 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.
