RE: Open or exterior corridors

What in the IBC is requiring this, the only difference I'm aware of (which is no longer a difference at least in the last cycle or two) is that Type V construction requires protection of porch/patio/decks. I don't believe an exit corridor falls within those requirements? The intent was to coun

IMHO, the 3x rule does not apply. Only because I can't say with certainty that you can meet this requirement from A.10.2.7.2.1.3: "This works for small noncontinuous obstructions and for continuous obstructions where the sprinkler can throw water over and under the obstruction." It seems to me li

RE: Open Grate Flooring - Calculations

I'll take a stab.., I assume there is a roof (ceiling) system installed? If so, open grate flooring is nothing more than an obstruction below the sprinkler. Each section mentions it, and the mins/max. That being the case, would not 23.4.4.7.3 and 23.4.4.7.3.2 (16) apply? As the word "ceiling"

RE: open vs manual

"Open" is pretty much what it says. Can atmospheric air get into the system? Think of an open nozzle vs. a closed one with an element in it. Manual means human interaction to make it work. R/ Matt Matthew J. Willis, CWBSP Design Manager /3-D Specialist Rapid Fire Protection Inc.
