Engineered for lithium-ion battery risk environments including workshops, charging rooms, fleet facilities, and electric mobility operations.

FCL-X is a water-based, PFAS-free lithium-ion battery fire extinguishing agent engineered specifically for lithium-ion battery incidents. It is designed to mitigate the risks associated with thermal runaway events, reduce toxic gas release, and help limit reignition.
FCL-X extinguishers are UL listed for Class A fires and have been tested by SafeLabs and certified to the Dutch NTA 8133 standard.
Penetrates the Battery During Thermal Runaway
Rapidly Cools the Fire and Lowers Surface Temperature
Designed to help neutralize hydrogen fluoride (HF)
Foam and vermiculite sit on the surface. FCL-X is a water-based solution engineered to penetrate battery cells and target reactions at the source.
FCL-X is formulated to react with hydrogen fluoride (HF) gas generated during lithium battery incidents, helping neutralize it into more stable byproducts.
At elevated temperatures, lithium may react with water and release hydrogen gas. FCL-X is designed to create a protective barrier on lithiated graphite that helps limit hydrogen production.
In controlled testing, FCL-X has demonstrated measurable reductions in thermal output during lithium-ion battery thermal runaway events, with reported reductions of approximately 20% under test conditions.
Traditional foam and vermiculite act as surface barriers. FCL-X is formulated as an aqueous solution designed to penetrate battery cells through open vent pathways to address internal reaction zones during lithium-ion battery incidents.
In documented testing scenarios, FCL-X has demonstrated the ability to:
Help reduce thermal output in active battery events
Interact with byproducts such as hydrogen fluoride (HF)
Address residual electrical conditions in controlled environments

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. FCL-X has additional features to help limit toxic exposure to people and the environment.
No PFAS or harmful residue.
Proven effective in EV and battery storage fires
Stops lithium-ion battery reignition
Reduces toxic exposure like HF

“We work around lithium-powered devices every day. If we’re going to recommend protection, it has to be purpose-built.”
