Fire Suppression System
Inert Gas With the big push toward "Green", inert gasses have become a good choice as they are the most green of all of the Clean Agents. Inert gasses are defined as using one or more of the gasses Nitrogen, argon. CO2 is also found in one of the inert gas blends. Inert gasses work by removing the oxygen in the hazard to a point where it will not support a fire, but still high enough to support life. Design considerations when using inert gasses are pressure venting and volume. It is critical to design the system to achieve the correct concentration, and not remove too much oxygen in the room. Plus, venting of inert gasses is important as it displaces the air volume in the hazard area. AFT can assist in determining which agent is best suited to protect the hazard area (includes detection and control for the system.
Inert Gas Design
IG-01 (ARGON) = ARGON (100%)
IG-55 = NITROGEN (50%) + ARGON (50%)
IG-100 (NITROGEN) = NITROGEN (100%)
IG-541 (INERGEN) = NITROGEN (52%) + ARGON (40%) + CO2 (8%)
How do Inert Gases work as a fire suppression system?
The air we breathe has approximately 21% of Oxygen. Oxygen is the key factor in sustaining a fire and the key factor in keep us alive too!
By removing the oxygen, we will certainly extinguish a fire, but that comes with obvious problems. How do we sustain life at the same time?
Fires need more than 15% Oxygen to combust. Anything below this level of oxygen will not be enough for a fire to sustain combustion.

Luckily, we only need 12% plus of oxygen to survive and this is where the answer lies. To extinguish a fire and sustain life, we need to reduce oxygen from 21% (assuming were at sea level) to below 15%, but not less than 12%. This will extinguish a fire and sustain life at the same time.
