Foam fire extinguishers
A foam fire extinguisher effectively and neatly extinguishes class A fires, or fiber materials like wood, paper and textiles. It also extinguishes class B fires, like gasoline and oil fires. It can be used to extinguish burning electrical equipment, but care must be taken to observe the safe distance of 1000 V/1m.
Extinguishing with the foam film is easy due to its long operating time and good visibility. The foam does not make a mess, so there’s less subsequent damage. The foam effectively prevents reignition.
