The range of foam and water extinguishers is certified to BS EN 3 : 1996 and manufactured under an ISO 9001 approved quality system. The cylinders are deep drawn from cold rolled steel, centre welded and pressure tested to twice the extinguisher 's working pressure. Cylinders are externally coated with epoxy polyster (with phosphate under treatment) for maximum corrosion resistance and have passed the 480-hour salt spray test. The internal of the extinguisher bodies are coated with "performance polymer alloy" to prevent corrosion. The hot forged brass valve is fitted with a pressure indicator and can be tested "in service" as required by BS EN 3 : 1996. These extinguishers have also passed the 35KV electrical conductivity test BS EN 3-2 : 1996 Clause 4 Annex A.

 


Foam
Foam extinguisher, with aqueous flim forming addictive (AFFF), offers improved fire extinguishing abilities over water based extinguisher . The foams forms an aqueous flim which helps to prevent the release of fuel vapours while the foam blanket (from which the flim forming liquid drains) excludes oxygen from the fuel surface, extinguishing the fire and preventing re-ignition. The water content of the foam provides a cooling effect. The flim forming liquid, although heavier, floats on the surface of the fuel, due to it's surface tension.

Effective on B class hydrocarbon fuel fires such as oil , petroleum, aviation fuel, and is paticularly suitable where fast fire knockdown is essential. It is compatible with all dry powders. It's excellent wetting characteristics make it useful in combating Class A fire as well.

 

 

Water
The most commonly used type of fire extinguishant for Class A fires involving carbonaceous materials such as wood, textiles by cooling the fire and removing the heat needed for combustion.
