From 4th July 2025, certain AFFF (Aqueous Film Forming Foam) fire extinguishers will be phased out due to their environmental impact. The key concern is per- and polyfluoroalkyl substances (PFAS), often called ‘forever chemicals,’ which persist in the environment. If your business uses AFFF extinguishers, now is the time to assess your equipment and plan for a smooth transition.
What’s Changing?
Not all AFFF extinguishers fall under the ban. Manufacturers stopped using the banned substances in most models from 2016 onwards, so these can still be used after the 2025 deadline. However, older extinguishers that contain perfluorooctanoic acid (PFOA), perfluorooctane sulfonate (PFOS), or perfluorohexane sulfonic acid (PFHxS) must be removed and safely disposed of.
The ban stems from environmental regulations designed to reduce harmful chemicals. In 2022, The Environment Agency released a document outlining compliance and advice regarding PFOA in Class B foam extinguishers. This guidance led to the decision to phase out certain AFFF extinguishers by July 2025. Further discussions are ongoing about phasing out PFHxA-based foams, though a full ban on all fluorinated foams is not expected before 2030.
Do You Need a Foam Fire Extinguisher?
Foam extinguishers are designed for Class A (solid combustibles) and Class B (flammable liquids) fires. While useful in some industries, many workplaces don’t need them. Water-based extinguishers can handle Class A fires effectively, and carbon dioxide (CO₂) extinguishers are a clean alternative for Class B fires and electrical risks. Businesses should review their fire risks and ensure they are using the most suitable extinguisher type.
Choosing the Right Alternative
For those transitioning away from AFFF, there are effective replacements:
- Water mist extinguishers: Versatile, clean, and effective on multiple fire types.
- Fluorine-free foams (F3): Designed for Class B fires without the environmental concerns of AFFF.
- Dry powder extinguishers: Suitable for flammable liquids and gases but best used outdoors due to visibility and inhalation risks.
- CO₂ extinguishers: Ideal for electrical and flammable liquid fires, leaving no residue.
Next Steps
If your extinguishers have been serviced or replaced in the last few years, they are likely to be compliant. However, now is the time to confirm and prepare. Businesses should:
- Check extinguisher labels and manufacturer documentation for PFAS content.
- Arrange safe disposal for affected extinguishers through approved channels.
- Work with a fire safety professional to identify the right alternative for their needs.
