Foam Fire Extinguisher

Foam Fire Extinguisher Suitable For Class A & B FiresFoam extinguishers are perfectly suited and the main type of extinguisher for the modern office. They can be used on Class A and B fires such as wood, paper, textiles and flammable liquids. They are recognisable by their cream coloured band on the red extinguisher body.

Modern foam fire extinguishers are now an efficient and effective piece of fire fighting equipment. They contain Aqueous Film Forming Foam, best known as AFFF which is a synthetic foam with a low surface tension. The surface of flammable liquids are quenched and the foam spreads and acts as a seal. It also penetrates porous materials and calms the fire by the evaporation of water content in the foam.

The foam is dispersed by a nozzle that does not conduct electricity if the foam accidentally splashes on electrical equipment, but they can’t be used directly on electrical fires. When used on Class B fires, the foam creates a film on the surface of the liquid which prevents any fire from reigniting.

ABF foam fire extinguishers have recently been developed with the ability to tackle Class F fires. ABF basically means the classes of fire the extinguisher can be used on. Class F fires comprise of cooking oils and fats, making it ideal for many kitchens and mobile catering environments.

Many multi risk businesses often place foam and CO2 extinguishers together to get the best overall protection for their needs. This is due to the foam extinguisher being ideal for office and warehouse fires, while the CO2 is used to protect against electrical fires.

Refill costs are higher than water extinguishers due to disposal and environmental dangers associated with the foam. After using a foam fire extinguisher, proper care must be taken when cleaning up and disposing of the foam. AFFF is carcinogenic which can poison surface water such as rivers. Please get expert advice before cleaning up yourself.

A plus point for foam fire extinguishers is that it weighs less than typical water extinguishers. A 6 litre foam extinguisher has an equal fire fighting rating as a 9 litre water extinguisher and also weighs 30% less.

Foam fire extinguishers are ideal for a range of multi risk premises such as offices, restaurants, vehicles, petrol stations, garages, boats, caravans, kitchens and mobile catering.

How It Works?

Once the foam has been dispersed, it forms a layer which covers and quenches the burning materials.  This prevents reigniting and ultimately extinguishes the fire.

The Features & Benefits

✓ Smaller and Lighter with excellent fire fighting capability

✓ Ability to handle Multiple Fire Classes

✓ Added safety on electrical fires up to 35kv

✓ Flames are quickly dealt with

✓ Doesn’t impair visibility

What’s Suitable?

Foam fire extinguishers are suitable on Class A and B fires. This includes fires such as paper, wood, textiles, soft furnishing and flammable liquids such as petrol, oil, solvents, paint and lubricants.

They are specifically efficient on man-made pieces of decor as the foam stops fibres in the fabrics from liquefying due to the heat from the fire.

The Risks

They should not be used on electrical fires, even though most foam fire extinguishers have passed the 35kv conductivity test which adds extra safety to the user if it was accidentally used on electrical equipment.

They are still considered unsuitable for electrical fires as the user may still get an electric shock if situated in a residual puddle in the event the electrical equipment never short circuited.
