OK, well in his defense. He doesn't have anything other than a sprinkler drawing showing a max 12' storage height. The EOR has not provided the basis of his design criteria, ie , the OIC. In addition, he can drive 4 miles and walk in another identical store - same chain and see how they are storing.
To make things worse, the Sprinkler guy sent the AHJ 3 documents to prove the OH2 - 1) A Coffee Break Training sheet - one page only that discuss flue spaces, of which there are one in this facility 2) A page from NFPA #13 Chapter 16 - Rack Storage - and has two passages marked - one is about column protection not being needed if in racks are provided ( there are no in rack sprinklers, and the column protection is not the issue and the other is about foam protection - again not provided) 3) the table from chapter 13 with OH2 circled for 10-12' storage in palletized, bin box and shelf configuration - again, by definition this is not shelf storage. Therefore, the AHJ feels like somebody is blowing smoke and that pretty much ticks him off.
