Then sounds like the 168 limit if Light Hazard, yes. SL

This is an old wood building with 6ft deep main wood girders and the 3x9 holding up the wood deck. They are converting if from a OH II warehouse to an office. -----Original Message----- From: Sprinklerforum [mailto:[email protected]] On Behalf Of Steve Leyton Sent: Monday, August 04, 2014 1:46 PM To: [email protected] Subject: RE: Obstructed or un=obstructed construction If that's the only member, yes. But if there are 2x4 or other small sub-purlins within the bays formed by these 3x9's, then you're down to 130 sf.

Could it be panel construction - bays no greater than 300 sf? Does a nominal 3 x 9 meet the intent and definition of "member capable of trapping heat?" (Probably not ...)

Obstructed or un-obstructed construction? Just want to check because 168sf vs 225sf spacing makes a big difference on this project.
