These particles ‘suffocate’ the fire and also create a wall of mist between the fire and the person using the extinguisher, reducing the feeling of heat. This synthetic foam has a low viscosity and spreads rapidly across the surface of most hydrocarbon fuels. The foam not only cools down the fire but also helps to seal the surface, preventing the release of flammable vapours. The fire extinguisher is supplied filled and ready to use with a durable base, wall fixing bracket, protective plastic lining and a unique spray nozzle, designed to comply with Dielectrical test to EN3-7 clause 9 ensuring the users safety is not compromised should the extinguisher accidentally get used on electrical fires.

Extinguisher – The foam extinguishers are a lot smaller than their standard water equivalents but carry the same Class A Fire rating. Both types of fires can be found on construction sites and the CO2 fire extinguisher ensures the fires are cleared in rapid succession. The foam extinguisher works by smothering the flames and creating a barrier between the fire and the oxygen, thus extinguishing the fire rapidly and preventing re-ignition.

Providing fire extinguisher coverage but not at the expense of decor, this stainless steel foam extinguisher is often fitted in lobbies and reception areas. Carol Browner, the USEPA Administrator in 1998, described Pyrocool as the "Technology for the Third Millennium: The Development and Commercial Introduction of an Environmentally Responsible Fire Extinguishment and Cooling Agent".

As they are much lighter than other types of extinguishers, foam fire extinguishers are very user friendly and are, for the most part, non-toxic and will not cause long-term damage to most materials. Foam fire extinguishers are highly effective in tackling Class A and Class B fires, which involve solid combustible materials and flammable liquids respectively. Its active agent is a fluorinated surfactant that provides an oil-rejecting property to prevent contamination. Novel Fluorinated Surfactants Tentatively Identified in Firefighters Using Liquid Chromatography Quadrupole Time-of-Flight Tandem Mass Spectrometry and a Case-Control Approach". This six-litre unit from CommanderEDGE boasts a new and improved 21A 183B fire rating, is Kitemarked and 35kVa dielectric test certified.Petrol, kerosene, diesel, alcohol, and certain oils and greases can cause Class B fires, which foam fire extinguishers can also be used to tackle.

Pros: non-toxic, non-damaging to most materials, largely safe if accidentally used on electrical fires (although this is not recommended), designed to prevent the re-ignition fires, lighter in weight than the equivalent water extinguisher. Dry Powder Fire Extinguisher A versatile fire extinguisher that can be used on Class A, B and C fires.In any case, the paperwork that came with the item recommends the bracket be attached to wall with stone or wood behind it. This FireGuard 6Ltr AFFF Foam Fire Extinguisher is amongst the most popular due to their ability to provide a fast and effective way of tackling fires involving flammable liquids. Sealing the surface, the foam extinguisher prevents stray materials from scattering and starting fires elsewhere. All products carry a full warranty and guarantee and are supplied with relevant fixings where applicable.
