36 CFR Parts 1190 and 1191 ADA and ABA Accessibility Guidelines - Preamble (Discussion of Comments and Changes)

Comment. A commenter advised that no revolving doors or turnstiles should be permitted on an accessible route.

Response. As indicated in the proposed rule, manual revolving doors, gates, and turnstiles cannot be part of an accessible route (404.2.1). The Board has included a provision clarifying that automatic types of revolving doors, gates, and turnstiles cannot be the only means of passage at an accessible entrance (404.3.7). While automated revolving doors, if large enough, may be usable by people with disabilities, certain questions remain about the appropriate maximum speed, minimum diameter, compartment size, width and configuration of openings, break out openings, and safety systems such as motion detectors that stop door movement without contact. An alternate door in full compliance with 404 is considered necessary since some people with disabilities may be uncertain of their usability or may not move quickly enough to use them.
