Susan, time to pull out the good book. Look at 2010 NFPA 13 chapter 15, specifically Table 15.2.2.
For back to back shelf storage of cartooned unexpanded group A plastics. Ceilings of less than 30'-0" Over 5'-0" up to 8'-0" OHII Up to 15'-0" 0.7/2500 Remember that if your top shelf is at 8'-0" they will store above that, so then your 8'-0" storage is actually 10 or 11'-0" and your required design goes to .45/2500 All of this is based upon the Fire Protection Research Foundation study of "Evaluation of sprinkler performance in protecting Gondola type shelf storage" Thom McMahon, SET Firetech, Inc. 2560 Copper Ridge Dr P.O.
