At the U of KY, they use a CO2 system for the flammable liquids, although I'm not sure they have that system in all storage areas.  INERGEN is another inert system option that I can send you more information about off-list, along with some engineering contacts.

Some of the biggest issues with water in a chemical storage/stock room are 1) water incompatibles, 2) what to do with the runoff when the EPA comes knocking on your door, 3) widespread water damage, and 4) building-wide contamination if the storage area is not on the lowest level of the building (the contaminated runoff will flow down through the various levels, soaking everything along the way).

As to 1) see my discussion of the storage of water incompatibles around sprinkler systems or pipes:  http://www.ilpi.c om/msds/ref/waterreactive.html   As to 2), 3), and 4), I'd say CO2 sounds *really* good.

I would like to have input as to what are the requirements,
recommendations or criteria for fire suppression in a chemical
stockroom.  Ours is ca. 400 ft^2, containing all the basics: gen org,
gen inorg, oxidizers, poisons, flammables, reactive metals, corrosives
(the latter 5 groups are in separate, ventilated cabinets).  We
currently have a CO2 system, but we are creating a second store room,
and want to know if we need a non-water suppression system.  Many
thanks!  Barry Ferm, St. Ambrose University.  FermBarretA**At_Symbol_Here**
