The ANSI A117.1 provision is the same as IBC 1003.3. Look at IBC section 1003.3.2 and -.3 and you’ll note that they exclude handrails and clearly intend this provision to include stairs.
The circulation path has to be kept clear (the clear-width prescribed in IBC 1003.3.4). Projections include those which are outside of the clear-width, and are still subject to the 4” limitation. There is no exclusion or exception for standpipe hose valves. I would however, suggest that the 4” is measured perpendicular to the point of travel, which is why it is ok to have water faucet in a hallway alcove. As such the valve could be placed off the “side” of the riser where it wouldn’t protrude more than 4” from the riser as measured perpendicular to the path of travel. Travis _____ 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.
