Class A

Water

Water Family
Water extinguishers are suitable for Class A type fires involving combustible materials such as wood, paper and textiles. Water is a fast and efficient means of extinguishing these materials. It works by having a rapid cooling effect, so that insufficient heat remains to sustain burning and continuous ignition ceases.

Manufactured in both stored pressure and gas cartridge versions, water extinguishers are available in two models: 9 and 6 Litre.
