Foam fire extinguishers are ideal for multi-risk situations where class A and B risks exist. Class B fires, those involving flammable liquid, such as petrol, diesel, spirits, solvents and lubricants, can be tackled very effectively.
The foam fire extinguishers, which are available in both gas cartridge and stored pressure versions, contain an aqueous film forming foam which gives rapid flame knock-down and has a blanketing effect, smothering the flames and sealing vapors to prevent re-ignition.
All models have a spray nozzle which produces a very effective spread of foam, even when used by and inexperienced operator. All spray models have passed an electrical conductivity of discharge test which means that if accidentally used on electrical equipment, the spray foam will not conduct electricity.
