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

Comment. Section 407.3.1 recognizes acceptable types of elevator doors. The proposed rule recognized horizontal sliding doors. A comment indicated that other door types recognized by the elevator code should be recognized, such as vertical sliding doors.

Response. In the draft of the final guidelines, the Board had included a reference to vertical sliding doors permitted by the elevator safety code (ASME A17.1) in response to this comment. A similar change was not approved for the ANSI A117.1 standard due to concerns about such doors posing a tripping hazard to persons with vision impairments. For consistency, the Board has removed the reference to vertical sliding doors in the final rule.
