Occupational Therapy Advice and Information

Further advice for people with visual impairment:
- Step Nosing should have a contrast in colour to the rest of the step and should extend the full width of the step and be 55mm deep on both the tread and the riser of each step.
- A tactile warning surface should be incorporated at both the top and the bottom of a set of steps, where appropriate, and be a minimum 800 mm depth and between 1000 mm & 1500mm wide. The tactile surface should be provided 400 mm from the nosing of the step.
- Steps should be uniform and slip resistant.
- Treads should preferably be 300 mm but no less than 250 mm.
- Risers should be between 150 & 170 mm and not open.
- If the visually impaired person requires walking equipment then the steps will need to have deeper treads of preferably 450 mm.
Specific work needs to be done to ensure that there are additional triggers that will assist people with visual impairment to negotiate steps and reduce the risk of trips and falls to a bare minimum.
