Air leakage and smoke ingress are detrimental to an installation’s firefighting capabilities and can result in massive failure of your critical asset. Ensuring compliance for server room integrity testing compliance should be at the top of the agenda for all facility management companies.
The effectiveness of a gaseous fire suppression system can only be guaranteed, if the enclosure surrounding it is air tight. Unfortunately if the system does not operate effectively, by maintaining the correct concentration for an effective time period,- usually 10 minutes) it may cause the whole system to fail resulting in critical system failure.
Previous studies have revealed that the predominant cause of failure of gaseous extinguishing systems is inadequate room sealing to the building envelope. It is also found that room integrity performance reduces with time, usually due to changes in construction, mechanical and electrical services as well as a natural breakdown of sealing materials such as mastic and/or sealing foam etc.
Ensuring good room integrity should be shown the highest priority. And once the room/enclosure has passed its annual server room integrity test, it should be carefully maintained throughout the year. Any extra works undertaken to the room envelope within the annual test period may result in the need to undertake another integrity test.
The room integrity door fan test is undertaken in accordance with the general requirements specified in BS:ISO 14520, NFPA 12A, NFPA 2001 and isroutine practice for most major companies. The insurers and regulatory authorities usually insist on annual room integrity testing. It is worth noting in the event of a critical failure of your protected enclosure, if you don’t have complaint certification you may void your buildings insurance.
