I’m curious whether any of you have run across this application before, and how it was handled. In the image below you can see the situation – the guards at the top of the bleachers need to prevent access to the bleachers when they are not in use, but those same gates have to allow egress when the bleachers are occupied. The AHJ’s concern is that the bleachers could be extended for use and the guards accidentally left in place, preventing egress in that direction.
I checked the IBC, as well as ICC-300 – Standard for Bleachers, Folding, and Telescopic Seating, and Grandstands, and didn’t find any specific requirements. It seems like it must be a fairly common situation, so let me know if you have seen it before or have ideas about a solution that would be acceptable to the AHJ.
