Storage Protection in the Presence of Horizontal Barriers or Solid Shelving – Literature Review

Fire Protection Research Foundation report: “Storage Protection in the Presence of Horizontal Barriers or Solid Shelving – Literature Review"
Authors: Garner Palenske, P.E., and Garth Ornelas, M.S.

There is limited guidance related to storage protection and horizontal barriers in NFPA 13, Standard for the Installation of Sprinkler Systems. In addition, the terms horizontal barrier and shelves are both used in NFPA 13 with differing protection strategies. For example, one form of alternate protection in NFPA 13 is to provide a solid horizontal barrier and provide sprinklers around the perimeter of the barrier, including face sprinklers. On the other hand, the shelf requirements do not require face sprinklers. Another potential issue is that shelves larger than 64 square feet require sprinklers under each shelf, but there is no limit to tiers of storage under each shelf.
