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.

Subject: [DCHAS-L] When is non-water fire suppression required in a chemica
l stockroom?

We are in the design phase of creating a new, modest-size chemical
stockroom, which is considered an occupied space.  Is it current
standard to have fire suppression that uses a non-aqueous agent?  Does
it depend on what chemicals are present?  It will definitely house
general organics, acids and flammables.  Is there a prevailing design
philosophy I can present to the decision-makers?
