Gaseous fire suppression is a clean fire suppression agent which protects sensible datas or documents.
Gaseous fire suppression is a term to describe the use of inert gases and chemical agents to extinguish a fire. Also called clean agent fire suppression. These agents are governed by the National Fire Protection Association (NFPA) Standard for Clean Agent Fire Extinguishing Systems – NFPA 2001 in the USA, with different standards and regulations in other parts of the world.
Typically, the system consists of: agent, agent storage containers, agent release valves, fire detectors, fire detection
system (wiring control panel, actuation signaling), agent delivery piping, and agent dispersion nozzles. Less typically, the agent may be delivered by means of solid propellant gas generators that produce either inert or chemically active gas.
There are four means used by the agents to extinguish a fire. They act on the “fire tetrahedron”:
The most important advantage of the use of chemical gas is that it is safe for people and electronic equipment.
During fire fighting, gas is used in a concentration not to be harmful to human health and life. When using an inert
gas, concentration of oxygen in the room is reduced by 3%. Along with the fact that such a composition of the air
is not sufficient to continue the fire, it allows people who are there to breathe.
The use of chemical gas is also very advantageous in places of storage of expensive electronic equipment and
important documents. The most harmful effect that may occur in areas of fire is the possibility of a small drop
in temperature. In terms of data storage and carriers, installation of gas fire extinguishing is the most effective
One of the advantages of gas extinguishing is the time used to extinguish the fire. The experimental results and
data on extinguishing of real fires show that the use of chemical gas prevents fire within 15 seconds.
Another advantage of the system is that it is compact and takes very little space for storage. In systems of gas fire extinguishing, extinguishing agent is stored in cylinders as a liquid. This system is reliable - because in a parallel manner used electric (leakage controldevice) and visual (with manometers) monitoring.
