GAS SUPPRESSION SYSTEMS
Gas Suppression Systems have an inert or synthetic gas stored in high pressure cylinders. In the event of a fire the gas is released out of the cylinders into discharge pipework and directed to the relevant area where the fire has been detected.
Inert gas systems will displace enough oxygen though pressure relief vents fitted in the wall such that the oxygen concentration is lowered to the point where fire cannot be sustained.
Inert gases include:
Synthetic gas systems chemically react with
the fire to cotrol it. These gases include:
INERT GASSES ALLOW FOR MULTIPLE AREAS
TO BE PROTECTED WITH A CENTRAL BANK
Room Integrity Testing & Fire Stopping
Gas suppression systems require the room including any voids that form part of the protected risk to be sealed so that the agent is contained within the space for the required period. Any openings or gaps should fire stopped.
Room Integrity testing involves running a calibrated fan at a certain speeds to generate negative and positive pressure within the space. By monitoring the pressure differential inside and outside the space and inputting the data into a software programme we are able to calculate the leakage in the room and the hold time of the Aerosol.
