The International Symbol of Access, as shown in Figure 3.8.3.1.-A below, indicates to persons with disabilities that they will have reasonable freedom of movement within the building. It usually has a blue background, but if, because of lighting conditions, it may not stand out, it can be set on a white background. An arrow can be added to either side or to the top or bottom to indicate direction or the location of an accessible space or facility.
An International Symbol of Access for Hearing Loss, shown in Figure A-3.8.3.1.-B, indicating accessibility for persons with hearing loss, should be used to indicate the availability of variable volume controls on telephones, assistive listening systems, and text telephones (TT). These latter devices may also be referred to as teletypewriters (TTY) or telecommunications devices for the deaf (TTD).
