'''INERGEN''' is a blend of inert atmospheric gases that contains 52% [[nitrogen]], 40% [[argon]], 8% [[carbon dioxide]], used for fire suppression system agent. It is considered a [[clean agent]] for use in [[gaseous fire suppression]] applications. Inergen does not contain [[halocarbons]], and has no [[ozone depletion]] potential. It is non-toxic. Inergen is used at design concentrations of 35-50% to lower the(contracted; show full)

==Environmentally neutral==
Since Inergen is composed of natural components that exist in the air [[Nitrogen]], [[Argon]] and [[Carbon Dioxide]] its components simply resume their normal role in the earth’s life cycle following a discharge, so Inergen presents no environmental impact:


[[Ozone depletion]] potential (ODP) is zero.
[[Global warming]] potential (GWP) is zero.
[[Thermal decomposition]] products (TDP) are zero.
[[Atmospheric lifetime]] (ALT) is zero.
In summary there are never any environmental restrictions on use. 

It should be noted that although many other [[Halon (disambiguation)|Halon]] replacement agents have a zero ODP, they may not have zero values for GWP, TDP and ALT. This may see restrictions placed in the future with changes in environmental legislationIn the modest quantities used by firefighting the above gasses have no [[Ozone depletion]] or [[Global warming]] issues.

==Equipment safe==
Many other agents break down in the combustion process forming by-products that are corrosive to electronic components and cards. Inergen does not form any corrosive by-products. 

Inergen is discharged into the protected area in a “single phase” so there is no thermal shock or large temperature drop associated with the discharge. Discharge tests conducted demonstrate that the temperature drop is typically less than 2°C in room temperature.
