4Bell KO

Description

Lithium-ion fires don’t follow the rules

Lithium-ion fires don’t follow the rules. They reignite, they explode, they overwhelm conventional agents and outlast every suppression strategy the fire service has relied on for generations. Electric vehicles, battery storage systems, and lithium-powered infrastructure have introduced a new category of danger, one that has threatened lives, destroyed facilities, harm the environment, and left entire industries without a credible answer – until now.

4Bell KO™ is a fire suppressant proven to stop lithium-ion thermal runaway, completely, safely, and without a single toxic chemical. All-natural, PFAS-free, non-corrosive, and non-toxic, it penetrates faster and suppresses deeper than any conventional agent and eliminates reignition where every other agent fails. This isn’t an improvement on what came before. It’s the product the industry has been waiting for.

4Bell KO™ was built by firefighters

4Bell KO™ was built by the firefighters who faced these fires firsthand, professionals who refused to accept that thermal runaway was an unsolvable problem. The result is a Class A, B, D, K, and L rated suppressant that performs across the full spectrum of modern fire response: field extinguishers, fire engines, tanker systems, and large-scale fixed suppression infrastructure. Proven. Certified. Ready to deploy.
