Oxygen Reduction Fire Prevention for Tunnels
Protect critical tunnel infrastructure with FirePASS® oxygen reduction fire prevention. Designed for suitable protected tunnel environments, FirePASS uses controlled oxygen reduction to significantly reduce the risk of ignition and help prevent potentially catastrophic tunnel fires.
Unlike conventional tunnel fire suppression systems, which respond after a fire has started, FirePASS provides proactive protection by controlling the atmosphere within designated protected areas.
- Continuous tunnel fire prevention without water discharge
- No chemical residue or cleanup, helping minimize operational disruption
- 24/7 protection for critical equipment, infrastructure and technical installations
- Precisely controlled oxygen levels through continuous monitoring and regulation
- Engineered for demanding tunnel fire protection environments and critical infrastructure
More Than Tunnel Fire Suppression
Traditional tunnel fire suppression systems are designed to control or extinguish a fire after ignition. FirePASS takes a preventive approach by continuously maintaining an engineered oxygen concentration within the protected environment.
At the controlled oxygen setpoint, conditions are created in which common combustible materials are far less likely to ignite. This makes oxygen reduction fire prevention a proactive solution for suitable tunnel applications where fire safety, infrastructure protection and operational continuity are critical.
Protect Critical Tunnel Infrastructure Before Fire Starts
Tunnel fires can have severe consequences for infrastructure, equipment, operations and safety. Preventing ignition can therefore provide an important additional layer of protection alongside other tunnel fire safety measures.
FirePASS provides continuous fire prevention for protected tunnel environments, helping reduce ignition risk while minimizing reliance on water- or chemical-based fire suppression.
