Behind the term inert gases are the four extinguishing agents nitrogen, argon, IG 541 (trade name Argonite) and IG 55 (trade name Inergen). All four extinguishing agents reliably suffocate the fire by reducing the oxygen content to at least 12% in the air. The gas concentration must be maintained for a specified time in order to prevent the fire from igniting again. Inert gases are suitable for fires of fire classes A (solid substances), B (flammable liquids) and C (flammable gases) including electrical and electronic equipment. Which of the four extinguishing agents is most suitable depends on the protection goal as well as the structure of the property.
In the event of a fire, the first thing people present are to be warned visually and acoustically to leave the room. Only then is the room evenly flooded with one of the inert gases. Intergases are residue-free, they leave no damage to the objects in the danger area. Depending on the structure of the object, the inert gas can be ventilated or extracted from the object. Only then can people enter the property again.
Inert gas extinguishing systems consist of the gas bottles with the respective extinguishing agent (nitrogen, argon, IG 541 or IG 55), extinguishing nozzles, triggering device and pipeline including pressure reducer, and a fire alarm system with extinguishing system control. The gas bottles must be stored in a separate room.
Areas of application for inert gas extinguishing systems are e.g. B. server rooms and cabinets, switchgear, control rooms, operating and control rooms, building services rooms, paint and powder coating systems as well as hazardous materials storage. People present must be warned by visual and acoustic alarms (danger of suffocation due to the displacement of oxygen).
You can easily manage inert gas extinguishing systems with our all-round carefree package: CWS analyzes the local conditions, plans, develops and installs the inert gas extinguishing system. You will receive the extinguishing system "turnkey" and we will take care of the regular maintenance.
Inert gases are natural gases.
