inertgasystem

An inert gas system is a fire suppression system that uses inert gases to extinguish fires. Inert gases are naturally occurring gases such as nitrogen, argon, and helium, or a combination of these. These gases work by reducing the oxygen concentration in the protected space below the level required to sustain combustion. When the system is activated, the inert gas is rapidly discharged into the room or enclosure. The rapid release displaces the normal atmosphere, effectively suffocating the fire by lowering the oxygen content.

Inert gas systems are commonly used in applications where water-based systems could cause significant damage to valuable equipment or materials, such as in data centers, museums, archives, and electrical switchgear rooms. They are considered environmentally friendly as they do not produce harmful byproducts and the gases are readily available in the atmosphere. The effectiveness of an inert gas system relies on the enclosure being sufficiently sealed to prevent the inert gas from escaping too quickly. Once the fire is extinguished, ventilation is required to restore the oxygen levels to a safe breathing concentration for occupants. The discharge of inert gas can also lead to a temporary reduction in visibility and a potential decrease in temperature.
