Our Fire Suppressant Solution
What is FCL-X?
FCL-X is a water-based, PFAS-free lithium-ion fire extinguishing agent made specifically for lithium-ion battery fires. It’s designed to stop thermal runaway, reduce toxic gas release, and prevent reignition – something traditional agents like water or foam can’t do.
Tested by SafeLabs and certified to the Dutch NTA 8133 standard, FCL-X has been proven in multiple real-world EV fires and industrial training burns.

How FCL-X Works
Lithium-ion battery fires are complex and dangerous. They involve intense heat, toxic gas release, and the risk of reignition – even after the flames are out. FCL-X is designed to stop these fires at the source by addressing the unique chemical reactions happening inside the battery.
Penetrates the Battery During Thermal Runaway
FCL-X soaks into the battery structure, reaching deep into cells that are undergoing thermal runaway. This direct contact helps interrupt the chain reaction before it spreads to other cells in the battery pack.
Rapidly Cools the Fire and Lowers Surface Temperature
As a water-based agent, FCL-X cools the fire quickly, reducing the heat energy driving the reaction.
Lower temperatures slow down chemical reactions, contain the spread, and give responders control.
Buffers Lithium Oxidation and Suppresses Hydrogen Generation
FCL-X interrupts the lithium oxidation process that fuels the fire and generates flammable hydrogen gas. By slowing this process, it limits the risk of gas buildup and secondary explosions.
Prevents Reignition and Flashovers
Even after the flames are out, a battery can reignite minutes – or even hours – later. FCL-X creates a protective barrier that helps stabilize the battery and prevent dangerous flare-ups.

Safety Driven Technology
Non-PFAS Formulation
FCL-X uses a proprietary suppressant blend free from perfluorinated chemicals (PFAS), avoiding long-term health risks tied to cancer, liver toxicity, and bioaccumulation.
Respiratory Safety
Upon deployment, FCL-X minimizes hazardous smoke and airborne particulates – reducing the risk of inhalation exposure, especially critical for non-SCBA responders.
Low Residue Toxicity
After burn tests, FCL-X shows non-corrosive, non-conductive residue that doesn’t pose dermal or respiratory hazards during post-fire cleanup or inspection.
No Secondary Combustion Risk
FCL-X does not emit flammable or explosive gases when heated – eliminating the risk of suppressant-induced ignition or overpressure scenarios.
Minimized Exposure
Suppression agents should reduce toxic smoke, airborne particulates such as HF and CO, and be an environmentally friendly product.
Rapid Knockdown & Cooling
Measurable cooling to stop thermal runaway and re ignition, which reduces firefighter fatigue on scene.
