It's the oldest one I have. I got this 1961 Edition from an old boss, it's in near-perfect condition and has no pencil or pen marks and of course no high-lighted sections. It's only a 144 pages in length (4 1/2" x 7")
It has a June 1961 date and I was born the following month (July, 1961) David Autry Plans Examiner Nebraska State Fire Marshal's Office 246 S. 14th Street Lincoln, NE 68508 402-471-9659 402-471-3118 fax www.sfm.ne.gov -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Mike Brown (TECH- GVL) Sent: Wednesday, March 12, 2008 3:55 PM To: [email protected] Subject: RE: Pipe scheduled systems - head stagger When I started in 1971, I think that we were only doing stagger spacing for extra hazard but if you have a 1961 NFPA 13 that is a treasure and there are not many left around.

My 1961 Edition Light hazard need not be staggered, except under open wood joist. All others shall be staggered.

At that time you only had 1/2 (5.6K) and 3/4" (8.0K) sprinklers. You may also find some 3/4" pipe used on old pipe schedule systems.

What was the reasoning for this back then?
