Inergen is a mixture of 52% Nitrogen, 40% Argon and 8% CO2. However, in the event of a fire, when Inergen is discharged, it mixes with the air present in the room to create a mixture that comprises of 67.3% Nitrogen, 12.5% Oxygen, 17% Argon and 3.2% Carbon Dioxide.
This discharge mixture makes Inergen singularly unique. No other inert gas has the unique ability to rapidly extinguish a fire yet at the same time provide a safe environment for any person within the occupied area by actually decreasing cardiac distress and maintaining arterial blood oxygenation and mental performance in low oxygen levels.
Equally important, unlike some chemical gaseous fire suppression agents, Inergen does not, and could never create a reaction with a fire to create extremely harmful toxic or corrosive by-products.
