Fire Hazard Classification?
(OP)
For a 10'x12' automotive paint mixing room (closed cap system), can we provide the one-hour fire barrier between this room and the retail space WITHOUT installing an automatic sprinkler system?
Also, how do you determine the "Fire Hazard Classification"?

RE: Fire Hazard Classification?
It depends on the amount of flammable and combustible liquids you are storing and the occupancy classification.
Also, tell us a little more about the building. I understand it has retail space and a paint mixing room? Are they doing automotive repair?
Is the building protected by automatic sprinklers?
RE: Fire Hazard Classification?
The retail space is part of leased space in an existing strip mall. The existing retail space and strip mall does not have an automatic sprinkler system.

MSDS sheets state the following:
- Paint, Flammable Liquids UN 1263
- Flash Point (closed cap): -4 to 160 F
- Approx. flammable limits: 0.8% - 16%
- V.O.C. (lbs per gal.): 0.0 - 7.5
- when heated above the flash point, emits flammable vapors which, when mixed with air, can burn or be explosive.
RE: Fire Hazard Classification?
Based on your explanation your lease space is most likely a Group M occupancy.
Using the 2006 International Fire Code you are limited to a maximum allowable quantity of 120 gallons of Class IB & IC Flammable Liquids. If your client can maintain the quantities below this amount, no separation from the paint mixing room and the remainder of the building is required.
You can increase the quantity by 100% if the flammable liquids are stored in cabinets.
If your client needs more flammable liquids, one can construct up to four control areas. These are individual areas separated from the remainder of the building by a minimum 1-hour fire barrier.
If the client needs even more storage, I would recommend moving the bulk of the storage outside and using a hazardous materials locker designed and installed in accordance with NFPA 30.
