individuals in wheelchairs; or they shall have wash basins mounted higher, when particular designs demand, so that they
are usable by individuals in wheelchairs.
d. Some mirrors and shelves shall be provided above the wash basins at a height as low as possible and not higher than 1 m
above the loor, measured from the top of the shelf and the bottom of the mirror.

An appropriate number of public telephones should be made accessible to and usable by the physically disabled.
a. Such telephones should be kept so that the dial is placed at minimum 1200 mm from the loor and the handset may be
reached by individuals in the wheelchairs.
10. Handrails
Handrails are used as a locational and mobility aid by blind and visually impaired people and as a support for people with mobility
impairments. The handrail should be securely itted to the wall to withstand heavy pressure. Handrails should turn in towards the

of approximately 45° to the wall so that they are easier to read and operate. To cater to wheelchair users, controls should
be placed at not less than 400 mm from the corners of the room. All the power and electric points should be placed at one
metre above the loor level and should not project outside the walls.
b. Again, to cater to the visually impaired people, controls should be colour-contrasted with backgrounds. Information should
preferably be in relief for tactile reading.
c. To aid operation for people with impaired co-ordination or impaired vision, switches should have large push plates.
d. Controls for powered door openers to hinged doors should be located so that the doors do not conlict with wheelchairs,
sticks, walking aids, and so on.
