Same reason a Home Depot is not OH2, I don't think it meets the definition in '10-5.3.2
Agree, design to the stated intent. Actually 6' of group A plastics in the IFC calls for HPS compliance (got smoke control?). I recall the guy making 5 gallon buckets was not happy because the old UFC I think was 5' and he couldn't maintain that low. I can't imagine where I would go OH2. But if you are convinced it's Class IV and it complies with shelf definition then table '10-13.2.1 does appear to support OH2. Looks to me like EH2 from table '10-13.2.1 for exposed, shelf to 12'. '07 - 20.3 I'd accept being, I think, a little on the high side but there are specific shelving requirements that the store probably doesn't meet. But 0.6 is more than 0.4 so I wouldn't probably care about the shelves.

If questions are going to be raised about if they will stack over 12' on 12' racks, one might also wonder if they will change the racks out for taller racks, etc. Wouldn't the design have to be based on the stated intent for the tenant? I agree that this is probably on the high side of what OH2 was intended for. It could also be protected by the retail storage criteria (NFPA 13 2007 20.3). From a sign-off responsibility standpoint, it seems like it could be approved. If I was their insurance carrier, I might be more concerned.

For example the 2009 International Fire Code deals with retail storage of aerosols in Section 2806 with <8 ft and >8 ft categories. Flammable and combustible liquids are covered in IFC 3404.4. Then there are the Group A plastics determined by the product itself or the packing material covered in IFC Chapter 23. Note the definition of high-piled high-hazard commodities could start at >6 ft. Ceiling height was not noted. This could dictate maximum storage height. Without looking at any further I'd say the chance of OH2 would be slim. Looks like NFPA 13 is applied for the shelf storage question per IFC Section 2307. Maybe this major chain store already has corporate guidelines. Bill Brooks William N. Brooks, P.E.

I think in spots it is more than a class 4 commodity.

The PE has stated OH2 throughout the store. AHJ is asking questions because there are 12' tall racks with a solid top making him think they will store over 12'. Questions, Are solid shelves allowed in racks aver 30" deep in this scenario without protection in the racks? Is OH@ appropriate for these "typical" Auto Parts Stores with the storage as it is?
