I have a fire marshal wanting me to show him where in NFPA 13 it dictates the minimum and maximum spacing of in-rack sprinklers. This is a good question, for the life of me I have never found it in black and white. I know that there are several references to 8'-0" maximum spacing per sprinkler for storage up to 25'-0" but we are only storing up to 20'-0". I have always been under the impression that you space a sprinkler in each in-rack flue space, usually on the center point of the rack or at the rack upright. Normally the racks are spaced around 8'-0" O.C. but there is one here that is 4'-0" O.C. We are using intermediate level in-rack sprinklers with the overhead system being ELO sprinklers-no ESFR, Large Drop, etc... We are using NFPA 13, 2002 Edition here in Florida.
