Hello, NFPA 13 quoted at bottom w/ the relevant code section: With the 15 ft. extending into the lesser hazard is the intention to make this extended area part of the hydraulic design area (to be included in calcs) or simply to extend the results of the calculations into this area? My impression is the latter but I would like to see if people concur with that.
Thanks, RB NFPA 13: 2007 11.1.2 (1) Where areas are not physically separated by a barrier or partition capable of delaying heat from a fire in one area from fusing sprinklers in the adjacent area, the required sprinkler protection for the more demanding design basis shall extend 15 ft (4.6 m) beyond its perimeter. _______________________________________________ Sprinklerforum mailing list [email protected] http://lists.firesprinkler.org/listinfo.cgi/sprinklerforum-firesprinkler.org
