Chapter 16 directs you to use the criteria from Chapter 13, specifically Table 13.2.1. It's not "Misc. Storage" by definition, it's a storage occupancy, but you still go to the Misc. Storage criteria for basis of design. You didn't say what the actual or worst case configuration is proposed to be, but according to that table, Class IV commodity stored 10-12' in double-row racks requires EH-1. ≤10' would be OH-2.
If your client knows better, gently explain that they're wasting their time on you and they should expend their energies convincing the fire official. Steve L. From: Sprinklerforum [mailto:[email protected]] On Behalf Of Brian Harris via Sprinklerforum Sent: Wednesday, January 29, 2020 7:45 AM To: [email protected] Cc: Brian Harris Subject: Misc. Storage Just want to confirm per the definition of Misc. Storage (3.9.1.18 NFPA 2013) that just because something is stored less than 12' high doesn't automatically make it misc. storage. Working on a project that is 42,000 sq.ft. and the owner is storing Class I-IV commodities on double row racks. Says he was told as long as he doesn't exceed 12' high he only needs OH-2 protection at the ceiling... Brian Harris, CET BVS Systems Inc.
