It looks like the code refers to protruding objects on circulation paths. I have always had to keep standpipes and hose valves out of the circulation path – that might remove the requirement.
Also – maybe a dumb question – is ANSI A117.1 an adopted code in your jurisdiction? Matt From: Sprinklerforum [mailto:[email protected]] On Behalf Of James Litvak Sent: Tuesday, November 14, 2017 1:57 PM To: [email protected] Subject: ANSI A1171.1 Figure 307.3 I'm working on building permit plans for a job, and the architect passed on an email from their accessibility consultant that the fire department hose valves can't protrude beyond the standpipe riser more than 4", per ANSI A117.1 figure 307.3. The text of that section is: 307.3 Post-Mounted Objects. Objects on posts or pylons shall be permitted to overhang 4 inches (100 mm) maximum where more than 27 inches (685 mm) and not more than 80 inches (2030 mm) above the floor. Objects on multiple posts or pylons where the clear distance between the posts or pylons is greater than 12 inches (305 mm) shall have the lowest edge of such object either 27 inches (685 mm) maximum or 80 inches (2030 mm) minimum above the floor. What they're saying is that we will need to turn an elbow up from the outlet of the standpipe and install the valve vertical. I've already told them this won't work anyway, since the valve itself has a 5" hand wheel, and due to takeouts, the least amount of projection physically possible is about 8". According to the consultant, the way to mitigate this is to install cane protection, which the architect appears to want to avoid. Is anyone aware of this code section, and does it apply the way I'm being told it does? In nearly 13 years as a designer, I've never been told such a requirement exists. James Charlotte, NC
