For standpipe hose connections within stairwells, does ADA (Americans with Disabilities Act) restrictions apply to the dimensions of hose valves coming off pipe?
ADA - 2010 Standard
307.2 Protrusion Limits. Objects with leading edges more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the finish floor or ground shall protrude 4 inches (100 mm) maximum horizontally into the circulation path.
307.3 Post-Mounted Objects. Free-standing objects mounted on posts or pylons shall overhang circulation paths 12 inches (305 mm) maximum when located 27 inches (685 mm) minimum and 80 inches (2030 mm) maximum above the finish floor or ground.
In particular, I'm wondering if the 4" protrusion limit applies to standpipe hose connections off of a vertical standpipe, and if it does, if it only applies if the standpipe hose connection is pointed into the path of egress?
I would imagine there's some life safety experts that could explain this better than I surely am.
