36 CFR Part 1194 - Proposed Information and Communication Technology (ICT) Standards and Guidelines NPRM - Preamble

407.12.3.1 Unobstructed Forward Reach (Section-by-Section Analysis)

This section proposes that, where an unobstructed forward reach is provided, the operable part must be located 48 inches high maximum and 15 inches high minimum above the floor. An unobstructed forward reach, for purposes of this section, occurs when the operable part is located at the leading edge of the maximum protrusion within the length of the vertical reference plane of the ICT. These dimensions and their resulting geometry are consistent with the ADA and ABA Accessibility Guidelines (36 CFR Part 1191, Appendix D, sections 306 and 308).
