I'm designing the sprinkler system for a warehouse where class IV fabrics (costumes) will be stored. There will be a separate area where Class III props will be stored.
The problem I'm running into is as follows: the fabrics and props are not going to be stored in a manner outlined in NFPA 13. The fabrics will be on pipe racks and the props will be stored on the floor with walls separating them. These commodities don't comply with miscellaneous storage due to their height. They are also not stored in pallets/bin-box/racks/solid piled/back2back as discussed in chapter 14.
Can NFPA 13 be used to design the sprinkler system for this project? Does anyone have any guidance on which design criteria from NFPA 13 or from another source should be used for such an application?
Thanks in advance!
