One big problem is design professionals who don't know to ask for MSDS or who can't read them when they get them.
I didn't read that the scenario in question was a mercantile operation. Craig L.

When quantities exceed the MAQ in Table 307.1(1), the various design options being discussed come into play. The concept of Control Area is defined in (2009) IBC Section 414.2. The IBC fire barrier is noted in Table 414.2.2. I'm very surprised any AHJ would have to be educated on this, but looking back at the messages it may be that what the AHJ said was being filtered through a number of people who were not familiar with the process used to deal with hazardous materials. What I've found in the real world is the lack of correlation between commonly generated MSDS and the various building and fire code classification tables which does not appear to factor into this application. I'm not familiar with the Florida Building Code, perhaps it is much more complex than the IBC. Keep in mind there are 13 Exceptions listed under Section 307.1, one of which (Exception 2) is the storage of flammable and combustible liquids in mercantile. If it were not for this exception some stores we regularly shop in would not exist in their present form. Also Exception 6 is your neighborhood State Store (a nod to George C.).

It may be your job is not so complicated if you apply NFPA 55. But somebody else may or may not have done their job. Bill Brooks William N. Brooks, P.E.

It is 3000 cu ft per control area. Don't know where the AHJ is coming up with 12000 cu ft unless he is considering the maximum of 4 control areas per building and then you get to 12000 cu ft. This means 4 areas that are fire separated from each other and the rest of the building.

Issue: Medical Gas Storage of 02 only in various cylinders. The tenant and owner of this Commercial / Industrial Strip center is having difficulty with the AHJ who claims that even if they classify the warehouse portion of this space as Storage Occupancy instead of Business, The maximum cubic footage of 02 allowed to be stored in one place is 12,000 with "High Hazard" Sprinkler protection. The tenant needs to store almost 20,000 cubic feet. Does anyone have expertise in this area?
