An existing high-rise hotel project in central Florida has open exterior exit stairs. By code and local ordinances, standpipe hose connections are required to be in the stair (hose connections on the corridor next to the stair are not allowed).
Since the project is located in central Florida (with lowest one-day mean temperatures between 25-30 degrees F, according to Figure A.10.4.2(b) of NFPA 13-2016), is there any way to still use wet standpipes and route them in the stair? Doing so could involve enclosing the standpipe perhaps in a small shaft and keeping the hoses in insulated cabinets. Or in this case is the best option just to have the standpipe be dry to completely avoid any freeze potential?
