I think what the decision tree suggests is that the arrangement of exposed, expanded, group A plastic on a rack is pretty much guaranteed to burn up uncontrollably...even with sprinklers. They may want to look into a different storage arrangement. (solid shelves would put them into chap 15)
Also of note is A20.2 (13-2007): "Exposed, expanded plastic... ...This test commodity used in the large-scale sprinklered fire test proved to be the worst challenge..."

AFPsprink.com -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Dewayne Martinez Sent: Friday, January 22, 2010 10:14 AM To: [email protected] Subject: Exposed Expanded Group A Plastics I am having a problem coming up with design criteria for the following using NFPA 13 (07ed). Product: Exposed, Expanded, Group A plastic Foam Taxidermy forms (the type used for target shooting) in open shelf racks stored to 12' in a 20' high building. Aisle width is 4'. Total storage is around 40,000 SF. Since the storage is over 5ft and 4000SF, this puts us out of miscellaneous storage. When I use the decision tree in chapter 17, it tells me that I am outside the scope of ch17. Any suggestions?
