Chapter 4 technical bulletins of the online guide to the ADA & ABA Standards and protruding object animation shown in player windowThe next installment of the U.S. Access Board’s online guide to accessibility standards issued under the Americans with Disabilities Act (ADA) and the Architectural Barriers Act (ABA) is now available. This material features a series of technical bulletins covering requirements for accessible routes in Chapter 4 of the ADA and ABA Standards, including doors and gates, ramps and curb ramps, and elevators and platform lifts. There is also a bulletin on referenced requirements for accessible means of egress. The documents explain and illustrate requirements in the standards, answer common questions, and offer best practice recommendations.

These bulletins join those released last year when the Board launched the online guide. The first installment provides guidance covering the first three chapters of the standards, including application and use of the standards, scoping in new construction, alterations, and additions, and basic “building block” technical provisions.

The online guide also features a popular series of animations that covers wheelchair maneuvering, entrances and doors, and toilet and bathing facilities. The new installment adds to the series an animation on hazards that protruding objects pose to people with vision impairments. This animation demonstrates standard cane technique, different examples of wall-mounted and free-standing protruding objects, and various treatments to reduce hazards and to make objects comply with specifications in the standards.

The Guide to the ADA Standards covers design requirements for places of public accommodation, commercial facilities, and state and local government facilities covered by the ADA. The Guide to the ABA Standards addresses similar standards that apply under the ABA to facilities that are designed, constructed, altered, or leased with federal funds.

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.
