The U.S. Access Board has released new chapters for its online guide to accessibility standards under the Americans with Disabilities Act (ADA) and the Architectural Barriers Act (ABA). You can access these chapters here.
The new installments include information about requirements for accessible routes, including doors, ramps, elevators and exits. It also has an animated video on hazards that protruding objects pose to people with vision impairments. The guide covers design requirements for places of public accommodation, commercial facilities and state and local government agencies covered by the ADA.
Future installments to the guides will be published as they become available. Users can sign-up to receive email updates on the release of new technical guides in the series.
