How does oxygen reduction prevent fire?

Oxygen reduction prevents fire by controlling the amount of oxygen available for combustion. Fire requires sufficient heat, fuel and oxygen to ignite and continue burning. By reducing the oxygen concentration within a controlled environment, the conditions for ignition and combustion are significantly restricted.

FirePASS® continuously introduces oxygen-reduced air and monitors the oxygen concentration within the protected space. Rather than waiting for smoke or flames to trigger a suppression system, the protective atmosphere is maintained continuously.

This means oxygen reduction fire prevention works before a fire event develops, helping reduce the risk of ignition and subsequent fire damage.
