Room Integrity Testing

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 except C0₂ total flood systams that requires a 20min retention Time.

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.
