GENERAL SITUATION
It is not always possible to eliminate the use of steps or stairs or to provide alternative ramped approaches to cope with changes in level. But the presence of steps or stairs can often make parts, or even the whole, of a building completely inaccessible to wheelchair users. They can, additionally, be a real hazard to the visually impaired and to anyone who has difficulty in walking.
DESIGN CONSIDERATIONS
- Tactile surfaces should be used to give advance warning of a change in level. This is particularly important at the head of a flight of steps.
- Steps should be at least 1 metre wide. The preferred depth, or going, is 300 mm but, in general, they should not be less than 250mm.
- Risers, which should not be open, should be between 150 and 170mm. There should be no more than 12 risers in a stepped access route. The provision of isolated single steps should be avoided.
- Step nosings should be distinguishable through contrasting brightness.
- For recomendations on handrails (see factsheet on Handrails).
CHECKLIST
- Do the steps conform with the required dimensions? ( )
- Are the edges of steps easy to see? Is use made of coloured nosing, are the steps well lit? ( )
- Are there tactile surfaces at the foot and head of steps/stairs? ( )
