What is a Foam Fire Extinguisher?
A Foam Fire Extinguisher is specifically designed to tackle fires fueled by flammable liquids, such as oil and petrol, along with solid combustibles like wood and paper. The foam works by creating a barrier between the fuel and the oxygen needed for combustion, effectively smothering the flames.
Types of Foam Fire Extinguishers
There are primarily two types of foam extinguishers available on the market:
AFFF – Aqueous Film Forming Foam
AFFF extinguishers are suitable for Class B fires and are designed to form a film on the surface of flammable liquids, preventing re-ignition. They are highly effective and commonly used in various settings, including garages and industrial facilities.
Alcohol-Resistant Foam
Alcohol-resistant foam extinguishers can be used on polar solvent fires, in addition to regular flammable liquids. They are essential in environments where alcohols are present, such as laboratories and certain manufacturing industries.
Advantages of Foam Fire Extinguishers
Using a Foam Fire Extinguisher comes with several advantages:
Versatility
As mentioned earlier, foam extinguishers can combat both Class A and Class B fires. This versatility makes them suitable for many locations, saving the need to carry multiple types of extinguishers.
Effective Cooling
The foam acts quickly to cool the burning material and the surrounding area, which helps mitigate the risk of fire spread.
Minimized Damage
Unlike water extinguishers that can damage sensitive equipment and cause further hazards, foam is generally safer for areas with electrical components, as it does not conduct electricity. This feature makes it ideal for use in offices and data centers.

Flammable Liquid Fires
If a fire involves liquids like petrol, paint, or oil, a Foam Fire Extinguisher should be used to smother the flames effectively.
Solid Material Fires
For fires involving solid materials, like wood or paper, the foam can cool and absorb the heat, preventing re-ignition.
How to Use a Foam Fire Extinguisher
Utilizing a Foam Fire Extinguisher is straightforward. Follow these steps:
- Pull the safety pin from the handle.
- Hold the extinguisher upright and aim the nozzle at the base of the fire.
- Squeeze the handle to release the foam.
- Use a sweeping motion to cover the area of the fire with foam.

Annual Servicing
Have a qualified technician perform a detailed inspection and servicing annually to ensure optimal performance.
Training Staff
Ensure that all personnel are trained in the correct use of foam extinguishers. Familiarity can save lives in an emergency.
Conclusion
The Foam Fire Extinguisher is a valuable tool in fire safety that can save lives and property when used correctly. Understanding its functionality, types, and maintenance will enhance safety measures in any environment.
