AFFF Foam Fire Extinguishers

What is an AFFF foam fire extinguisher?

An AFF foam fire extinguisher, sometimes referred to as an AFFF foam fire extinguisher, is designed to tackle both Class A and Class B fires.

AFFF stands for Aqueous Film Forming Foam. When discharged, it creates a thin film that spreads across the surface of a flammable liquid, helping to smother the fire and prevent re-ignition.

Our in-house experts often recommend AFFF foam fire extinguishers where flammable liquids are present, but where a versatile extinguisher is also needed for general fire risks.

AFFF Foam Fire Extinguisher FAQs

What does AFFF stand for in fire extinguishers?

AFFF stands for Aqueous Film Forming Foam. Our in-house experts describe it as a fast-acting foam that spreads across flammable liquids to suppress flames and reduce the risk of re-ignition.

What types of fires can an AFFF fire extinguisher be used on?

AFF foam fire extinguishers are suitable for Class A fires involving wood, paper and fabrics, as well as Class B fires involving flammable liquids.

Can AFF foam extinguishers be used on electrical fires?

They can be used on electrical equipment only once the power has been isolated. Our experts usually recommend pairing AFF foam extinguishers with a CO₂ extinguisher for electrical risks.

What sizes of AFFF foam fire extinguishers are available?

Common sizes include 6 litre and 9 litre models. The correct size depends on the fire risk and the size of the protected area.

Which foam fire extinguisher would you recommend?

Our in-house experts recommend the FireSmart ECO Foam Fire Extinguisher for most Class A and Class B fire risks.

It delivers strong performance against fires involving solid materials and flammable liquids, while being completely fluorine-free and better for the environment.

Available in 6-litre and 9-litre sizes, it suits everything from smaller commercial spaces to higher-risk environments where extra coverage is needed. The advanced foam formula forms a thick blanket over the fire to cut off oxygen and provide effective cooling, helping to prevent re-ignition.

For customers looking for reliable, modern fire protection without the environmental concerns of traditional AFFF foam, this is the option our team most often points to.
