Government confirms 2025 ban on PFOA and PFOS in firefighting foams
OHEAP has welcomed the UK government’s decision to implement a complete ban on Perfluorooctanoic Acid (PFOA) in firefighting foams, which will take effect from 4 July 2025.
According to OHEAP, Perfluorooctane Sulfonate (PFOS) was banned in foam extinguishers more than ten years ago, and the use of PFOA has been largely phased out.
The upcoming ban aligns with international efforts to remove persistent organic pollutants that pose environmental and health risks.
OHEAP has raised concerns about industry misconceptions regarding the ban, noting that some organisations have begun removing existing fluorine-based extinguishers unnecessarily.
The company advises that while PFOA will be prohibited, there are currently no legal restrictions on C6 fluorotelomer-based extinguishers.
Industry impact and transition to fluorine-free alternatives
The ban is expected to shape future fire safety practices, requiring businesses to adopt fluorine-free alternatives.
The Fire Industry Association (FIA) has recommended that organisations start considering a transition to these alternatives to reduce environmental impact.
Under the new regulations, any product containing PFOS, PFOA, or PFHxS above the prescribed limits will be prohibited.
However, there is no immediate requirement to remove existing fluorinated extinguishers that do not contain these banned substances.
Nicholas Heap, Managing Director of OHEAP Fire and Security, said: “We want to make sure every person responsible for fire safety understands what is banned and when.
“There are so many mistruths out there, that people are making decisions about fire safety that they may not need to.
“The truth is that the ban in July 2025 will not affect many units at all as the chemical that is being banned hasn’t been used for more than 10 years.
“But the ban is still an important step into creating a greener, safer, more sustainable environment.”
Future regulations on PFAS in fire extinguishers
The UK government is reviewing further legislation to restrict the use of Perfluoroalkyl and Polyfluoroalkyl Substances (PFAS) in firefighting foams.
A full ban on PFAS-containing extinguishers is not expected before 2026, with a phase-out period extending towards 2030.
OHEAP has advised that while the PFOA ban is imminent, organisations should remain aware of potential future restrictions.
The FIA continues to provide updates on the regulatory landscape and recommendations for businesses preparing for a transition.
Heap added: “At OHEAP, we fully support this initiative and are committed to helping our clients navigate this transition smoothly.
“As an industry, we must prioritise environmental responsibility without compromising safety standards, and whilst a ban on PFAS is still a way off yet, our team is actively implementing fluorine-free firefighting solutions across our services.”
Consultation underway on broader PFAS restrictions
A UK government consultation is ongoing to assess the impact of banning PFAS in firefighting applications.
Any resulting legal restrictions are not expected before 2026.
OHEAP advised fire safety professionals to stay informed and monitor official guidance from regulatory bodies.
More information on the use of PFAS in firefighting can be found on the FIA website.
UK firefighting foam regulations: PFOA and PFOS ban set for 2025 – Summary
OHEAP has welcomed the UK government’s decision to ban Perfluorooctanoic Acid (PFOA) in firefighting foams from 4 July 2025.
PFOS was already prohibited in foam extinguishers more than a decade ago.
The new restrictions align with global efforts to eliminate harmful pollutants.
OHEAP has warned against industry misinterpretations, stating that there is no immediate need to remove fluorine-based fire extinguishers unless they contain the banned substances.
The Fire Industry Association (FIA) has encouraged organisations to start transitioning to fluorine-free alternatives.
A broader PFAS ban is under review, with legislation expected by 2026 and a potential phase-out period lasting until 2030.
The UK government is conducting a consultation on the future of PFAS use in firefighting.
OHEAP and industry bodies continue to monitor regulatory developments, providing guidance to businesses on compliance and best practices.
