The U.S. Access Board has released guidance on the International Symbol of Accessibility (ISA) to address questions that have arisen on the use of alternative symbols. Some cities and states have adopted a different symbol that was created to be more dynamic and suggestive of movement. The Board's guidance explains how use of a symbol other than the ISA impacts compliance with the Americans with Disabilities Act (ADA).
Standards issued under the ADA require that the ISA label certain accessible elements, spaces, and vehicles, including parking spaces, entrances, restrooms, and rail cars. Similar requirements are contained in standards issued under the Architectural Barriers Act (ABA) for federally funded facilities. The ISA, which is maintained by the International Organization for Standardization (ISO), has served as a world-wide accessibility icon for almost 50 years.
"Consistency in the use of universal symbols is important, especially for persons with limited vision or cognitive disabilities," states Marsha Mazz, Director of the Board's Office of Technical and Information Services. "In addition to the ADA and ABA Standards, many codes and regulations in the U.S. and abroad also require display of the ISA."
While the ADA Standards do not recognize specific substitutes for the ISA, they do generally allow alternatives to prescribed requirements that provide substantially equivalent or greater accessibility and usability under a provision known as "equivalent facilitation." However, in the event of a legal challenge, the entity pursuing an alternative has the burden of proof in demonstrating equivalent facilitation. Under the ABA Standards, use of a symbol other than the ISA requires issuance of a modification or waiver by the appropriate standard-setting agency.
"The Board understands the interest out there to revisit the ISA but strongly recommends that such efforts be directed to the ISO to ensure consensus in adoption and uniformity in implementation," says Mazz.
