36 CFR Part 1195 Proposed Accessibility Standards for Medical Diagnostic Equipment NPRM - Preamble

Transfer Surface Size: Equipment Used by Patients in a Seated Position (M302.2.2)

Seats on diagnostic equipment used by patients in a seated position typically provide back and arm support for patient comfort and stability. The space available for transfer on diagnostic equipment used by patients in a seated position is smaller than the space available on diagnostic equipment used by patients in a supine, prone, or side-lying position.

On diagnostic equipment used by patients in a seated position, M302.2.2 would require the size of the transfer surface to be 21 inches wide minimum and 15 inches deep minimum. The 21 inches minimum width is based on the ideal chair width recommended in Architectural Graphic Standards for auditorium seating. See The American Institute of Architects, Architectural Graphic Standards (10th edition, 2000), page 919. The 15 inches minimum depth is generally consistent with the dimension specified in the 2004 ADA and ABA Accessibility Guidelines for rectangular seats in roll-in showers.

The transfer surface dimensions do not include headrests, footrests, or similar supports for body extremities that do not support the patient’s overall body position. A transfer surface is permitted to be contoured; however, the minimum dimensions would have to fit within the contoured surface and cannot be reduced to accommodate an asymmetrical shape.

Question 16. Comments are requested on the following questions regarding the minimum dimensions (21 inches wide and 15 inches deep) proposed for the transfer surface on diagnostic equipment used by patients in a seated position:

a) Do the above dimensions provide sufficient space for patients with disabilities to safely and easily transfer to the equipment?

b) Would alternative dimensions be appropriate for transfer surfaces? Comments should include information on sources to support alternative dimensions, where possible.
