Fire safety professionals across Europe are navigating a significant regulatory shift. The substances that have underpinned foam-based fire suppression for decades, per- and polyfluoroalkyl substances, collectively known as PFAS, are being systematically phased out under European law. For distributors, specifiers, and fire safety teams, this creates both a compliance challenge and a genuine opportunity to rethink what effective, responsible fire suppression looks like in 2026.
The pressure is not abstract. Regulation (EU) 2025/1988 sets a clear trajectory toward a complete ban on PFAS-containing extinguishing agents by 2031, and the industries most exposed to that deadline are precisely those already grappling with a separate and growing fire risk: lithium-ion battery fires. Understanding why PFAS-free fire suppression matters, and what it must deliver to replace conventional agents, is now a practical necessity for anyone operating in the fire safety sector.
How PFAS Regulations Are Reshaping Fire Safety Standards
European regulators have spent years building the scientific and legislative case against PFAS. These highly persistent synthetic compounds do not break down in the environment. They accumulate in soil, contaminate groundwater, and concentrate in living organisms over time. For fire suppression specifically, the concern centres on the use of PFAS-containing foams, which have long been valued for their ability to form a rapid, smothering film over liquid fuel fires. That performance came at a significant environmental cost that regulators are no longer willing to accept.
Regulation (EU) 2025/1988 formalises the phase-out, with a complete ban on PFAS-containing extinguishing agents scheduled for 2031. This gives the fire safety industry a defined window to transition, but that window is narrowing. For manufacturers, distributors, and procurement teams, the practical implication is clear: any fire suppression product specified or stocked today needs to be evaluated not only for current performance but for its regulatory position over the next five years. A PFAS-containing agent purchased now may become non-compliant before its service life ends.
The regulatory direction is also influencing procurement decisions beyond Europe. As international markets increasingly align with European chemical standards, the commercial case for PFAS-free alternatives strengthens globally. Fire safety professionals who build PFAS-free suppression into their product portfolios and specifications now are positioning themselves ahead of a compliance curve that will eventually reach most major markets.
Industries Most Exposed to PFAS Compliance Risk
Not every sector faces equal exposure to the PFAS transition, but several industries are in a particularly complex position because they face both regulatory pressure on suppression agents and escalating fire risk from lithium-ion battery systems simultaneously.
Warehousing, Logistics, and E-Mobility
Warehousing and logistics operations have expanded their use of electric forklifts, automated guided vehicles, and e-bikes at significant scale. Each of these systems carries lithium-ion battery packs that can enter thermal runaway if mechanically damaged, overcharged, or exposed to heat. A single thermal runaway event in a warehouse can cascade through adjacent battery cells, producing temperatures that conventional suppression agents struggle to manage. If that warehouse also holds PFAS-containing foam systems for fuel fire protection, it faces a dual compliance and performance problem.
Maritime, Recycling, and Energy Storage
Maritime operators, recycling facilities, and industrial energy storage installations share a similar profile. These environments often rely on foam-based suppression for liquid fuel or mixed-material fire risks, and they are simultaneously accumulating lithium-ion battery systems, whether in vessel propulsion, waste processing equipment, or grid-scale storage. The combination of legacy PFAS infrastructure and emerging battery fire risk makes these sectors particularly motivated to find suppression solutions that address both challenges within a single, compliant product framework.
Building managers and EV charging infrastructure providers face a related challenge at a smaller but more distributed scale. As EV charging points proliferate in car parks, residential buildings, and commercial premises, the fire risk associated with charging incidents becomes a mainstream building safety consideration rather than a specialist industrial concern.
What PFAS-Free Agents Must Deliver to Match Performance
Replacing a PFAS-containing agent is not simply a matter of removing a chemical and substituting water. Effective fire suppression, particularly for lithium-ion battery fires, requires a combination of capabilities that water alone cannot reliably provide.
Lithium-ion battery fires are fundamentally different from conventional fires because the energy driving the incident originates inside the battery cells themselves. Mechanical damage, overheating, or improper charging can destabilise a cell and initiate thermal runaway: a self-sustaining sequence in which rising temperature causes internal materials to decompose, releasing flammable gases including hydrogen and methane, as well as toxic and corrosive hydrogen fluoride. Pressure builds, the cell casing can rupture, and heat transfers to adjacent cells, triggering a cascading failure. Temperatures during thermal runaway can reach approximately 850 to 1,500 degrees Celsius, and gas release can continue even after visible flames appear to have been extinguished.
Against this background, a credible PFAS-free suppression agent must do more than suppress visible flames. It needs to cool the fire source rapidly and sustain that cooling over time, limit heat transfer to adjacent cells, reduce concentrations of flammable and toxic gases, and prevent re-ignition, which remains one of the most significant challenges in battery fire management. Any PFAS-free alternative that cannot address these requirements in combination is not a genuine replacement; it is simply a compliant product that leaves performance gaps in the scenarios where those gaps matter most.
Hydrogel as a PFAS-Free Suppression Solution
Anogas developed Hydrogel specifically to address the full complexity of lithium-ion battery fire suppression without relying on PFAS or other environmentally harmful compounds. The product is composed primarily of water and modified natural clay, both naturally derived components, and contains zero PFAS, with a carbon footprint of less than 0.7%.
The suppression mechanism is built around temperature-sensitive gel formation. As a low-viscosity liquid at ambient temperature, Hydrogel can be applied through standard water-based systems. When it contacts hot surfaces, it thickens into a viscous gel that adheres to battery cells and other surfaces rather than running off. This adhesion is central to its effectiveness: the gel maintains continuous contact with the heat source, sustaining cooling where it is needed rather than dissipating rapidly like water.
Five Mechanisms Working Together
Hydrogel’s suppression approach combines five mechanisms simultaneously. Rapid cooling and flame extinguishment come first, driven by the product’s high water content. Thermal isolation follows as the gel forms a physical barrier around affected cells, limiting heat transfer to adjacent cells and interrupting the cascading failure sequence that defines thermal runaway. The gel also suppresses and neutralises hazardous gases: it reduces concentrations of flammable hydrogen and methane, restricts oxygen availability, and interacts with hydrogen fluoride to convert it into less harmful ionic components.
The fourth mechanism is lithium-ion stabilisation. Modified clay particles within the gel penetrate damaged battery structures and bind reactive lithium ions, reducing chemical reactivity inside the battery and contributing to longer-term stabilisation after visible flames have been extinguished. The fifth mechanism is re-ignition prevention, achieved through the sustained combination of cooling, thermal insulation, gas suppression, and chemical stabilisation. Together, these mechanisms address the full lifecycle of a battery fire incident rather than targeting only its most visible phase.
Hydrogel is certified according to KIWA NTA 8133 for lithium-ion battery fire applications and is supplied as a ready-to-use premix requiring no on-site dilution or preparation. It is compatible with all water-based fire suppression systems and fully interchangeable with water, which means it can be integrated into existing infrastructure without system redesign. More detail on how Hydrogel works is available for those evaluating the technology for specific applications.
Environmental and Commercial Advantages for Distributors
For fire safety distributors evaluating their product portfolios in light of the PFAS transition, Hydrogel offers a combination of environmental credentials and commercial differentiation that is difficult to replicate with conventional alternatives.
On the environmental side, the product contains zero PFAS, confirmed at less than 1 ppb by the most accurate available measurement systems, making it fully aligned with current and anticipated European chemical legislation. Aquatic toxicity studies conducted according to OECD guidelines confirmed that Hydrogel is non-toxic for the environment. Because the gel adheres to hot surfaces longer than water alone, less extinguishing agent is required per incident, which reduces contaminated runoff and limits the environmental footprint of each suppression event. After a service life of more than ten years, Hydrogel is expected to be recyclable as a compost-enrichment supplement, completing a genuinely circular product lifecycle. The Hydrogel product page outlines the full sustainability profile for distributors conducting due diligence.
Commercially, the timing is well suited to distributors looking to build a differentiated position in the fire safety market. The combination of tightening PFAS regulation, rising lithium-ion battery fire incidents, and growing customer awareness of environmental compliance creates demand for exactly the kind of product Hydrogel represents. Distributors can offer a solution that addresses one of the fastest-growing fire safety challenges across warehousing, maritime, recycling, energy storage, and building management, all from a single, certified, PFAS-free product.
The product is available in formats suited to different distribution and end-user contexts, from 25-litre jerrycans through to 1,000-litre IBCs, and is applicable across handheld extinguishers and fixed suppression systems alike. For distributors building a forward-looking fire safety portfolio, that breadth of application, combined with a regulatory position that strengthens rather than weakens as PFAS legislation tightens, represents a meaningful and durable commercial advantage.
