Signs should be readable and legible for people who have vision or mental impairments. Well-illuminated, clear and readable signs shall be placed at a consistent height (see B-24.2.4).
Information with text should be supplemented with graphical symbols to facilitate comprehension for everyone (see B-24.2.16 for graphical symbols).
Signs should be provided in relief and Braille (see B-24.2.10).
The signs should be made of robust materials and be easy to change, clean and repair. Some suggested materials for signage are wood, acrylic and aluminium composite panel (ACP).
An excessive quantity of signs in close proximity should be avoided, as well as visual material placed too close to wall fixed signs (for example posters, timetables, etc).
Where Braille is used as a complementary or independent feature to tactile signs it should be easy to locate.
