I'm looking at an existing building with an existing overhead system. The owner decided to build a mezzanine with rack storage beneath it without a permit or sprinklers, and now after the fact the AHJ is demanding sprinklers. The racks are 2 x 4's with solid wood (OSB) sheathing 4' wide. I've ruled out treating these as shelves since they are over 30" deep. The area is approx.. 2900 sf allowing for this to be treated as miscellaneous storage. The storage height will be 8' +-. The commodity is class IV. All this leads me to Table 13.2.1 which tells me to use OH2 design criteria. The problem that I haven't resolved is the solid shelving. Chapter 13 only mentions in-racks under the section for Group A plastics and does not mention solid shelving at all. Other storage sections spell out the requirements for solid shelving, this one does not. Is it then the intention of chapter 13 to ignore solid shelves with class I - IV commodities?
