We are working on a project at Camp Pendleton, and a question has come up about running some piping exposed. We have a loading dock and originally indicated dry sidewall sprinklers to protect this area. However, due to some coordination issues with a soffit and structural steel, the contractor has proposed running a 2" branch line exposed with sidewall heads straight off of the branch line. I know that it is very common for large piping such as risers, backflow preventers, etc., to be run exposed in this area. However, I'm not as comfortable with a branch line. We've researched the Air Force Climactic Center data and that shows a 99.6% dry bulb temperature of 33F, which would suggest there would be very little to no chance of this line freezing. In the opinion of some of the esteemed West Coast members of this forum, should I be concerned about freezing? Christopher Born, P.E. Director, Fire Protection Engineering Clark Nexsen, P.E.
