36 CFR Part 1195 Proposed Accessibility Standards for Medical Diagnostic Equipment NPRM - Preamble
Transfer Supports (M301.3.1, M302.3.1, and M305.2)
M301.3.1 and M302.3.1 would require transfer supports to be provided for use with the transfer sides. M305.2.1 would require the transfer supports to be located within reach of the transfer surface and not obstruct transfer onto the surface when in position. M305.2.2 would require the transfer supports and their connections to be capable of resisting vertical and horizontal forces of 250 pounds applied to all points of the transfer support. M305.2.3 would require the transfer supports to not rotate within their fittings. These technical criteria are based on provisions in the 2004 ADA and ABA Accessibility Guidelines for grab bars.
Question 18. Comments are requested on the following questions regarding the structural strength of transfer supports:
a) Are transfer supports that can be repositioned (e.g., folding armrests, removable side rails) currently capable of resisting vertical and horizontal forces of 250 pounds applied to all points of the transfer support? If the transfer supports are not currently capable of resisting these forces, what would be the incremental costs for the design or redesign and manufacture of the equipment to provide transfer supports that are capable of resisting these forces?
b) Would alternative technical criteria be appropriate for the structural strength of transfer supports? Comments should include information on sources to support the alternative technical criteria, where possible.
Additional Technical Criteria Considered for Transfer Supports
As discussed below, the Access Board is considering whether additional technical criteria would be appropriate for transfer supports.
Location and Size
Midmark Corporation provided information based on input from accessibility experts regarding side rails on examination tables in comments submitted in response to the DOJ’s ANPRM on equipment and furniture. The side rails are similar in shape to grab bars and are located on each of the long sides of the table. Each side rail can be removed to permit patients to transfer onto and off of the table, and to permit health care personnel to perform diagnostic procedures. The side rails can also be relocated along the table surface (from foot-end to head-end) for patients to position or reposition their bodies, and to maintain static positions. The side rails are 20 inches minimum in length, 6 inches minimum in height above the table surface, and 1 inch measured horizontally from the adjacent edge of the table surface.
The Access Board is considering whether the following technical criteria would be appropriate for the location and size of transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position:
• At least one transfer support would be provided on the side of the transfer surface that is 15 inches deep minimum. The transfer support would be located on the side of the transfer surface that is opposite the transfer side (see M301.2.3 and M302.2.3) similar to the provisions in the 2004 ADA and ABA Accessibility Guidelines for grab bars provided at bathtubs and shower compartments with seats. This would be a minimum requirement. Where possible, it is recommended that supports be provided on each side of the transfer surface that is 15 inches deep minimum for patients to maintain position after they have transferred onto the equipment, and that the supports be repositionable to permit transfer.
• The transfer support would extend horizontally the entire depth of the transfer surface and would be 15 inches minimum in length.
• The gripping surface of the transfer support would be located 1½ inches maximum measured horizontally from the adjacent edge of the transfer surface. This would ensure that the transfer support is within reach and can be effectively used during transfers.
The above technical criteria would likely result in the transfer surface being located at the foot end of examination tables and allow the use of transfer supports similar to the side rails described in the information provided by Midmark Corporation.
Question 19. Comments are requested on the following questions regarding the above technical criteria for the location and size of transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position:
a) Are the above technical criteria for the location and size of transfer supports sufficient to facilitate transfer and maintain position on the equipment?
b) Can transfer supports on different types of equipment meet the above technical criteria for the location and size of the supports?
c) What would be the incremental costs for the design or redesign and manufacture of transfer supports that meet the above criteria?
d) Would alternative technical criteria be appropriate for the location and size of transfer supports? Comments should include information on sources to support the alternative technical criteria, where possible.
e) Should angled or vertical transfer supports be permitted?
Height
The Access Board is considering whether 6 inches minimum and 19 inches maximum above the transfer surface would be an appropriate height for transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position. The minimum height is consistent with the information provided by Midmark Corporation on examination table side rails, and the maximum height is generally consistent with the height of grab bars above shower seats in the 2004 ADA and ABA Accessibility Guidelines.
Question 20. Comments are requested on the following questions regarding the above height range (6 inches minimum and 19 inches maximum above the transfer surface) for transfer supports on diagnostic equipment used by patients in a supine, prone or side-lying position, and diagnostic equipment used by patients in a seated position:
a) Are transfer supports within the above height range usable by patients with disabilities?
b) Can transfer supports on different types of equipment meet the above height range?
c) Would alternative technical criteria be appropriate for the height of transfer supports? Comments should include information on sources to support the alternative technical criteria, where possible.
Cross Section of Gripping Surfaces
The 2004 ADA and ABA Accessibility Guidelines specify the following dimensions for grab bars to enable individuals with disabilities to firmly grasp the grab bars and support themselves during transfers:
• Grab bars with circular cross sections must have an outside diameter of 1¼ inches minimum and 2 inches maximum.
• Grab bars with non-circular cross sections must have a cross section dimension of 2 inches maximum and a perimeter dimension of 4 inches minimum and 4.8 inches maximum.
The Access Board is considering whether the above cross section dimensions would be appropriate for the gripping surfaces of transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position.
Question 21. Comments are requested on the following questions regarding the above cross section dimensions for the gripping surfaces of transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position:
a) Can the gripping surfaces of transfer supports on different types of equipment meet the above cross section dimensions?
b) Can handholds that meet the above cross section dimensions be integrated into the design of armrests that are cushioned to support arms and elbows?
c) Are there alternative designs for the gripping surfaces of transfer supports that enable patients with disabilities to firmly grasp the supports and support themselves during transfer?
Clearances Around Gripping Surfaces
The 2004 ADA and ABA Accessibility Guidelines specify the following clearances around grab bars to ensure sufficient space for a person to grasp the grab bar: 1½ inches absolute clearance between grab bars and the adjacent wall surfaces; 1½ inches minimum clearance between grab bars and projecting objects below and at the ends of grab bars; and 12 inches minimum clearance between grab bars and projecting objects above grab bars.
The Access Board is considering whether 1½ inches minimum clearance around the gripping surface would be appropriate for transfer supports on diagnostic equipment used by patients in a supine, prone, or side-lying position, and diagnostic equipment used by patients in a seated position.
Question 22. Can transfer supports on different types of equipment provide 1½ inches minimum clearance around the gripping surface?
