Australian Standard AS 4214 – “Gaseous Fire Extinguishing Systems” and AS 1851 – “Maintenance of Fire Protection Systems & Equipment” both require room integrity testing to be completed for “Total Flood” gaseous suppression system installations. Under these standards, room integrity is required to be tested initially as part of system commissioning, and then re- tested regularly there after.
AFE can provide trained technicians and the necessary equipment to test the integrity of the rooms in which your suppression system is housed.
The prime purpose of the room integrity test is to demonstrate how long a gaseous fire extinguishing agent remains in the room following discharge of a “total flood” gaseous suppression system. The longer the gas remains after the discharge, the better the level of protection.
All total flooding systems shall have the protected enclosure checked to locate and then effectively seal any significant leaks that could result in a failure of the enclosure to hold the specified extinguishing agent concentration level for the specified
Pressure Relief Venting
Integrity testing can also be used to predict the peak pressure likely to be experienced in the room during agent discharge. This is important to determine if the room is of sufficient strength to withstand the discharge pressure or if additional pressure relief venting is required. The correct operation of existing pressure relief vents can also be checked and the required size of additional pressure relief determined.
