Gaseous Fire Suppression or Clean Agent fire suppression are terms to describe gases used to extinguish fires. Typically, gaseous agents work in one of two ways, the first is to inert the atmosphere reducing oxygen levels to a level that will no longer sustain combustion, the second is to react chemically with the fire absorbing heat and causing the chain reaction of combustion to break down.
Gas suppression systems are typically used to protect three dimensional enclosures containing high value assets that are vital for business continuity, and assets that cannot be protected by traditional sprinkler systems due to the potential for water damage. Typical system applications include telecommunication facilities, clean rooms, data processing centres and museums.
