Most of us benefit from the availability of good and clear signage. This is particularly so for people with a vision and/or hearing impairment, people with a cognitive and/or intellectual disability and people with a brain injury. Many of the signs we find around the built environment are not easy to comprehend due to their location, type of font style used and the colours chosen. Lack of tactile and braille in signs requires people with a vision impairment to rely on others to assist them. Many of the people with cognitive disabilities are less able to comprehend a sign if it is all in upper case, however if the sign is in sentence case with upper and lower case, the accessibility if the sign is improved. Nine out of ten legally blind people have some usable residual vision. It is this group plus those with low vision that particularly benefit from the correct use of luminance contrast and the use of a sans serif font such as Arial or Helvetica medium. This also makes the signs more user friendly for the remainder of our community, especially those 1 in 10 males in Australia who have colour deficiency, often referred to as colour blindness. The location of signs is vital if they are to be easily identified and read, particularly signs indicating facilities for people with disabilities. Code Requirements
Signage requirements in the Building Code of Australia (BCA) in D3.6 are limited to the identification of accessible facilities, services and features. D3.6 refers to and requires compliance with relevant parts of AS1428.1. AS1428.1 specifies technical details such as dimensioning, and design criteria of the signage and symbols to be used. |
