Accessibility standards govern post-mounted objects and protruding hazards within circulation paths to ensure safe navigation for visually impaired individuals. Single posts or pylons permit signs and objects to overhang a maximum of 4 inches when positioned between 27 inches and 80 inches above the finished floor level. Multiple posts or pylons with clear distances greater than 12 inches require the lowest edge of the overhead object to remain at either 27 inches maximum or 80 inches minimum above the floor. Clear headroom clearance underneath obstructions must maintain a minimum of 6 feet 8 inches.
