Frequently Asked Questions

What Is A Foam Fire Extinguisher?

A foam fire extinguisher is a type of fire-fighting equipment that uses a mixture of water, foam concentrate, and air to extinguish fires. The foam creates a blanket-like layer over the fuel surface, which helps to smother the fire by removing the oxygen that it needs to continue burning. This type of extinguisher is particularly effective on Class A fires, which involve ordinary combustibles such as wood, paper, cloth, and other materials.

Foam fire extinguishers are often used in commercial and industrial settings, and they are especially useful for fighting fires in large open spaces where other types of extinguishers might not be effective. They are typically larger and heavier than other types of fire extinguishers, but they provide a longer discharge time and are more effective at extinguishing larger fires.

What Is A Foam Fire Extinguisher Used For?

A foam fire extinguisher is used for fighting Class A and Class B fires. Class A fires are fires that involve ordinary combustibles such as wood, paper, and cloth, while Class B fires are fires that involve flammable liquids, such as gasoline, oil, and grease.

The foam extinguisher works by smothering the fire, cutting off the supply of oxygen, and preventing re-ignition. The foam creates a barrier between the fuel source and the fire, extinguishing the flames. This type of fire extinguisher is especially useful for Class B fires, as it helps to prevent the spread of the fire and to cool down any hot surfaces that might be a hazard.

What Is A Colour Foam Fire Extinguisher?

Foam fire extinguishers are red in line with the EN3 manufacturing protocol with 5% being coloured in cream.

How To Use A Foam Fire Extinguisher

Using a foam fire extinguisher is a simple process, but it’s important to be familiar with the steps before an emergency situation arises. Here’s how to use a foam fire extinguisher:


Call the fire brigade: In any case of fire, it’s always a good idea to call the fire department, even if you think you’ve put the fire out.

Pull the pin: To release the locking mechanism and activate the fire extinguisher, pull the pin at the top of the unit.

Aim the nozzle: Point the nozzle of the fire extinguisher at the base of the fire, not at the flames.

Squeeze the handle: Firmly squeeze the handle of the fire extinguisher to release the foam.

Sweep the nozzle: Sweep the foam over the surface of the fire in a sweeping motion, starting at the base of the fire and working your way up.

Keep a safe distance: Stand a safe distance away from the fire and make sure to keep the fire extinguisher aimed at the fire.

Monitor the fire: After using the fire extinguisher, monitor the fire to make sure it’s completely extinguished and does not re-ignite.

It’s important to remember that foam fire extinguishers should only be used on Class A and Class B fires, and never on electrical fires. Before using a fire extinguisher, it’s also a good idea to assess the situation and make sure that it’s safe to do so. If the fire is too large or spreading too quickly, it’s best to evacuate the building and call the fire brigade.
