'''Inergen''' is a blend of inert atmospheric gasses that contains 52% nitrogen, 40% argon, and 8% carbon dioxide. It is considered a [[clean agent]] for use in [[gaseous fire suppression]] applications. Inergen does not contain halocarbons, and has no [[ozone depletion]] potentail. It is non-toxic. Inergen is used at design concentrations of 40-50% to lower the concentration of oxygen to a point that cannot support combustion.

(contracted; show full)

* Inergen is non-toxic, and does not create the same health risks as the use of halocarbon agents. In certain concentrations, halocarbon agents can cause heart palpitations.

* Inergen has the same density as normal atmosphere. No special considerations are needed in order to prevent agent leakage.

'''Disadvantages:'''


* Inergen is more expensive than carbon dioxide as it contains argon, which is much less abundant than either nitrogen or carbon dioxide.⏎
⏎
* Inergen requires more space for storage tanks. Unlike carbon dioxide or halocarbon agents, Inergen agent does not liquify under pressure.

* Inergen requires that 40-50% of the room atmosphere be replaced with Inergen in a short amount of time. This creates a large amount of pressure, which must be relieved in order to prevent damage to the enclosure.
