Room Integrity Testing
|
Gaseous fire suppression systems that protect enclosures should have room integrity tests when they are commissioned. It's a requirement of British Standards (ISO14520 / BS EN15004) and NFPA 2001 Code, that room integrity tests are conducted on initial installation and thereafter at least annually.
What is a Room Integrity Test?An Integrity test predicts how long fire suppressant agents take to descend to a given level in the room without having to release the gas itself. We seal the room and test the airpressure with our door fan and sensor equipment. First the room is pressurised and readings are taken, then to check those measurements the room is depressurised to take measurements to compare. The predicted retention time is calculated from the leakage characteristics and the enclosure and extinguishing system data. A retention time of 10 minutes is the normal minimum period the suppressant agents are required to be retained for. Ten minutes is long enough for most deep-seated fires to be cooled so that re-ignition is unlikely. Gaseous fire suppression systems should provide adequate time for the emergency services to attend and in most cases prevent the fire taking hold. |
