The term “protruding building elements” refers to elements regulated by this Code that are permanently affixed to the building and protrude into the path of travel.
The sweep of a cane used by people with vision loss normally detects protruding building elements that are within 680 mm of the floor. Any protruding element above this height would not normally be detected and can, therefore, create a hazard if it projects more than 100 mm into the path of travel.
