[labnetwork] Question: is a must to have CO2 fire suppression system for Polypro wet benches with heating ability

[Schweiger, Dennis]

Jianchao,

Your best answer should come from the Authority Having Jurisdiction (AHJ) for your facility, and your insurance underwriter.  I don't believe polypropylene materials will meet the NFPA code (FM 4910) for fire resistant materials within a clean room, which is typically a PVC-C material.

At UofM, we are not using gaseous fire suppression anywhere, as we could never get it to work for our facility (you have to damper the exhaust, it requires a huge number of tanks to get the suppression volume, etc...).  We do have our wet process stations (all of which are FM 4910 compliant for the clean room) on a separate sprinkler feed, so that in the event we have an issue, once it's mitigated, we can isolate the sprinkler system, without losing protection in the rest of the fab.

Hi guys,

We bought some used polypro wet benches which have heated quartz tanks. I am wondering whether it 's a must to have CO2 fire suppression system for them.

Or sprinkler system from the cleanroom will be enough.

Thanks,

J.C.
