In addition to checking local codes (as has been mentioned a couple of time s already), you need to look at NFPA 45 as well. Don A.

You need to check with your local codes. The international codes do not re quire this and we have not specified any chemical storage area with a non-a queous system, not even our chemistry department stockroom. There are other factors you'll need to consider if you're going with a CO2 or other system, including the ventilation and what to do it the system act ivates while it is occupied. Based on the discussions we've had with lab building designers for three ne w lab buildings over the last four years, it does not appear to be conventi onal to go with such a system. The international fire code lists storage q uantity limits based on the presence (or lack) of water-based fire suppress ion and use of flammable liquid storage cabinets. Another option is to look at a pre-action system, particularly if you're co ncerned about the possibility of leaks. - Robin Robin M. Izzo, M.S.

We are in the design phase of creating a new, modest-size chemical stockroo m, which is considered an occupied space. Is it current standard to have f ire suppression that uses a non-aqueous agent? Does it depend on what chem icals are present? It will definitely house general organics, acids and fl ammables. Is there a prevailing design philosophy I can present to the dec ision-makers? ________________________________ This e-mail and any attachments contain URS Corporation confidential infor mation that may be proprietary or privileged.
