This appendix contains materials of an advisory nature and provides additional information that should help the reader to understand the minimum requirements of the guidelines or to design buildings or facilities for greater accessibility. The paragraph numbers correspond to the sections or paragraphs of the guideline to which the material relates and are therefore not consecutive (for example, A4.2.1 contains additional information relevant to 4.2.1). Sections of the guidelines for which additional material appears in this appendix have been indicated by an asterisk. Nothing in this appendix shall in any way obviate any obligation to comply with the requirements of the guidelines itself.
A4.19.6 Mirrors. If mirrors are to be used by both ambulatory people and wheelchair users, then they must be at least 74 in (1880 mm) high at their topmost edge. A single full length mirror can accommodate all people, including children. Clear floor space for a forward approach 30 by 48 inches (760 mm by 1220 mm) should be provided in front of full length mirrors. Doors should not swing into this clear floor space. Mirrors provided above lavatories designed for children should be mounted with the bottom edge of the reflecting surface no higher than 34 inches (865 mm) above the finish floor or at the lowest mounting height permitted by fixtures and related elements.
