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. Mike Brown

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?
