In chapter 18 of the 2007 edition of NFPA it states that you need to have column protection if the columns are not fireproofed. 1 sidewall if storage not over 15ft and two if up to 25ft. In 18.2.4 it states that the requirements of 18.2.1 are not required if an ESFR system is installed and approved. Am I reading that correctly. If I design an approved ESFR system I would not have to have column protection correct. The building in question is a tire distributor building 35'0" in height storage up to 25'0" tires on side in protable racks with open grating approx. 128,000 sq. ft. so requiring 4 systems.
