I have a question
My question is why NFPA12 didn't require a room integrity test for rooms protected by CO2 fire suppression systems as for clean agent systems in NFPA 2001.
Even though NFPA 12 does not specifically state that enclosure tests MUST be performed, most major CO2 installations are tested for integrity for two reasons:
1. hold time
2. peak pressure development.
Failing either of these can make the installation not only incapable of keeping the fire from restarting but the peak pressure can destroy the enclosure and has in the past cost millions of dollars to fix. No one would save the small cost of this test and give up the security it represents if they realized they could be sued for not providing this test since it is common practice. Even though this may not be forced, the installer could not prove due diligence in court if they failed their client by not recommending this test.
10s of 1000s of CO2 installations have been tested for enclosure integrity using NFPA 2001 where CO2 is merely substituted as the agent.
