Fluorine-Free Foam Fire Extinguishers

As we move towards greener solutions, fluorine-free foam fire extinguishers are leading the way in the firefighting world. Opting for these over the traditional AFFF foam extinguishers is a smart move to future-proof your business, especially with the upcoming ban on their sale in 2026.

Also known as PFOA-free foam fire extinguishers, these are just as effective for Class A and Class B fires. This means they remain a versatile choice for offices, schools, warehouses, and workshops. They can tackle common combustibles like wood and paper and flammable liquids such as petrol, oil, and paint.

At Fire Protection Online, we offer a wide selection of fluorine-free fire extinguishers from trusted brands like Britannia and CommanderEDGE, available in various sizes to meet your needs.

What Makes Fluorine-Free Fire Extinguishers Environmentally Friendly?

Traditional (Aqueous film-forming foam) AFFF extinguishers are often called “forever foam”. This means that they are unable to break down in nature which makes them challenging to dispose of once their extinguishers reach the end of their usable life.

In more recent years, studies have found that the polyfluoroalkyl substances (PFAS) chemicals which make them effective at suppressing fire are not only harmful to the environment, but wildlife and people too. Many health problems have been linked to these chemicals.

Because of this, some of these chemicals have already been banned, with further restrictions set to follow in the next few years.

The new Fluorine-Free Foam Extinguishers which have come to the market in recent years are completely absent of these chemicals, making them a better choice for everyone, without compromising on their fire-fighting abilities. These are a foam concentrate and are similar to a water-additive fire extinguisher. Are Fluorine-Free Foam Fire Extinguishers Just As Good?
Fluorine-free foam fire extinguishers can be used as a direct replacement for AFFF foam fire extinguishers in the majority of situations. Their fire ratings are comparable and were designed with the intention of being a like-for-like replacement. They even still carry the cream label colour, and are labelled as Foam on the extinguisher themselves.
Additionally, our fluorine-free fire extinguishers still carry the same approvals, including CE Marks, UKCA approval and BSI Kitemarks along with standard warranties of 5 years or more.
This means businesses can prepare now for future environmental legislation on PFAS whilst remaining confident that staff and visitors are still completely protected.

How Does A Fluorine-Free Foam Fire Extinguisher Put Out A Fire?

The fluorine-free foam in your fire extinguisher works as a wetting agent, quickly covering and clinging to the surface of the burning material. This action cools the fire’s fuel, effectively slowing down the flames. For fires involving flammable liquids (Class B), the foam forms a protective layer over the surface, acting like a blanket to block the oxygen supply. This smothers the fire and helps prevent it from reigniting.

What Is A Fluorine-Free Foam Fire Extinguisher Used For?

Fluorine-free foam fire extinguishers are ideal for Class A fires, which involve solid, carbon-based materials like paper, textiles, and wood.

For Class B fires, which are caused by flammable liquids such as paint, oil, or melted plastic, PFAS-free foam extinguishers are a go-to choice. Their versatility makes them suitable for both commercial and home use.

However, fluorine-free foam extinguishers are not intended for electrical fires or those involving cooking oils.
