Here is the scenario; New warehouse addition to an existing sprinklered automotive parts distribution warehouse. Peak height = 36'-1", Rack height = 28'. Addition was originally specified for an ESFR system with racks. They came back and said they wanted to be able to store small quantities of flammable liquids. The insurance reviewer said OK add 1 level of in rack sprinkler where the flammable liquid storage would be. The customer said, we don't know it may move around depending on how much we have at any given time, so install sprinkler in all the racks. Yesterday I get the final rack layout drawings which call for solid steel shelving at the 12' and 28' levels. I responded that per NFPA 13, 2007 (the current recognized addition in PA) 16.3.3.2 you can't use ESFR with solid shelving. Now the customer wants to know. If we install in-racks at the 27' and 11' levels could we still use ESFR at the roof? (sort of defeats the purpose but it's not my money)I have spent the last hour going through chapters 16 & 17. I can't find anything that say you could do that. But I also haven't found anything that says you can't other than 16 .3.3.2 & 17.2.3.1.1. At this point I want to hang my hat on that and say no we can't. However I may be missing something so I thought I would throw it out for discussion.
