NFPA 13, 2007 A.22.4.4.8 The use of sprinklers with differing orifice sizes in situations where different protection areas are needed is not considered balancing. An example would be a room that could be protected with sprinklers having different orifice size in closet, foyer, and room areas. However, this procedure introduces difficulties when restoring a system to service after operation since it is not always clear which sprinklers go where. -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Randy Knutson Sent: Monday, June 15, 2009 11:42 AM To: [email protected] Subject: Mixing k-factors in paintspray booths Forum Members, Can I use a smaller k-factor sprinkler in the pit and exhaust plenum of a paint spray booth? Due to the geometry of the pit and exhaust plenum. The sprinklers in there are covering about 36 square feet per sprinkler. Any insight would be appreciated.
