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

(3) Adjustability: Transfer Surface Intermediate Heights

In the MDE NPRM there was no requirement for the transfer surface to have intermediate transfer heights. Under the proposed rule, diagnostic equipment would be in compliance if it provided a low transfer height anywhere within the range of 17 inches minimum and 19 inches maximum. In addition to the matter of low transfer height, the Access Board sought public comment in question 14(c) on whether the final rule should require intermediate heights between a minimum low transfer height and a minimum high transfer height. NPRM, 77 FR at 6923. Three commenters responded (two accessibility consultants and a disability rights advocate) and supported the idea of requiring intermediate heights within a minimum low height and minimum high height of the transfer surface. One commenter, an accessibility consultant, recommended intervals of ½ to 1 inch, indicating that ½ inch increments would be more practical to match the varying heights of wheelchairs and mobility devices, which is critical for many patients in performing independent transfers. The MDE Advisory Committee recommended adjustable height in small, virtually continuous increments. To support this recommendation, the MDE Advisory Committee explained:

• that adjustability greatly increases the overall accessibility of equipment for all persons. Adjustable height MDE, such as exam tables, imaging tables and chairs, will make it possible to position the transfer surface near the height of the seat of the mobility device. For some, independent transfers are only possible when there is minimal or no change in vertical height between the seat of the mobility device and the transfer surface. People may prefer or, in some cases, require, transfer to a slightly lower surface moving the transfer surface lower than the seat of the mobility device; then adjusting the transfer surface to above the seat for the return transfer.

The Access Board has decided to require that the height of the transfer surface be adjustable within the range for the minimum low and high heights in at least four unspecified intermediate heights, but has determined that the intermediate heights should be set a minimum of one inch apart. While the Access Board agrees that continuous adjustment is preferable, requiring such adjustability could preclude the use of certain types of lifting devices such as hydraulic systems that work in increments. The intent is to permit manufacturers flexibility in setting intermediate heights and not prohibitively restrict designs to those of particular manufacturers or equipment.
