36 CFR Part 1195 Standards for Accessible Medical Diagnostic Equipment - Preamble

M303.2.3 Depth (Section-by-Section Analysis)

The MDE NPRM proposed two wheelchair space depth requirements based on how the wheelchair user enters the space: for spaces entered from the front or rear, 48 inches deep minimum; and for spaces that can only be entered from the side, 60 inches deep minimum. In the preamble in the MDE NPRM, the Access Board noted it was considering increasing the minimum depth for wheelchair spaces entered from the front or rear to 58 inches and sought input in question 29 on whether the Access Board should increase this minimum depth requirement. NPRM, 77 FR at 6928.

The Access Board received eight comments in response to this question. Three commenters (two disability rights organizations and a state agency concerned with accessibility) recommended increasing the depth of front or rear entered spaces to 58 inches. The other five commenters (manufacturers, medical associations and accessibility consultants) recommended retaining the proposed requirement in the MDE NPRM of 48 inches minimum, raising concerns that the size of the rooms in which the diagnostic equipment are located are insufficient to provide additional space. The MDE Advisory Committee did not make recommendations regarding the general requirement for depth for wheelchair spaces, but did make recommendations regarding the depth of wheelchair spaces on raised platforms, which is discussed in above in Section IV.C.1. (Significant Changes – Width and Depth of Wheelchair Spaces).

First, the Access Board clarifies that this provision is not a clear space requirement for wheelchair approach, but is instead the wheelchair space integral to diagnostic equipment for a patient seated in a wheelchair, such as mammography equipment or wheelchair accessible scales. Second, based on the comments received and the absence of recommendations from the MDE Advisory Committee to change the proposed requirement, the Access Board has retained the MDE NPRM’s requirements for a minimum depth of 48 inches for wheelchair spaces entered from the front or rear, and a minimum depth of 60 inches for wheelchair spaces entered from the side. However, the Access Board has reorganized this provision into three separate requirements based on how the wheelchair space is entered, made an editorial change to clarify that front or rear entry is where the wheelchair space entry and exit is provided at only one end, and as discussed in Section IV.C.1. (Significant Changes – Width and Depth of Wheelchair Spaces), added an additional requirement to the depth provision for wheelchair spaces entered from the front or rear to permit a minimum of 40 inches if the wheelchair space provides pass-through from one end to the other.
