Whatever the protected room, it must be as airtight as possible in order to allow the retention of the gas for the time necessary for the suppression of the fire. The minimum time is 10 minutes, this may vary depending on the risk. The tightness of the protected volume must be checked by a blower door test. This test will take into account any non-stoppable leaks in the quantity of gas to be used. Beyond an admissible leakage surface, depending on the overall volume, the tightness of the room must be resumed because the increase in the quantity of gas would not be sufficient to compensate for the losses for a compliant retention of the gas concentration.
Hello, does the warehouse need to isolated so that the gas does not run away by little openings in the steel structure?
Thank you
