Escalators can be a useful addition to stairs and lifts where significant height
differences have to be negotiated, but they cannot be used by people with guide
dogs, nor with ease by elderly and mobility impaired people.
A lift must be provided where escalators are installed.
When stationary, escalators often have to act as stairways. They should not
be too steep, nor have steps too high, for people to use. The dimensions for
steps must be observed (see 6.3 Steps and stairs).
A clear approach distance is required at the top and bottom of escalators to
ensure that passengers - especially those leaving escalators - have adequate
space at the busiest times to board and alight safely. This distance may need
to be 10m or more at busy public venues such as railway stations.
The direction of travel and the destination should be clearly and prominently
indicated at the top and bottom of each flight.
Indicate the approaches to the top and bottom of escalators by a change of
floor texture to advise blind people, and provide an audible signal or pre-recorded
voice message. Do not use tactile surfaces specified in 5.6
Tactile paving as these are for use at fixed hazards, not moving escalators.
Lighting should be provided near to floor level with a visible change in lighting
at the bottom and top of each flight.
Treads should be clearly visible while avoiding glare and reflection.
Step edges should be clearly defined using a tonal and colour contrast, e.g.
yellow or similar colour.
Moving handrails should be rounded in section and in a colour which contrasts
with the background.
Handrails should have regular contrasting colour patches to help indicate when they are moving.
Travelators, or moving pavements, may be used when there are substantial distances
between pedestrian entrances and vehicular access points, for example in an
airport terminal. They are mechanically similar to escalators, may be level
or inclined, and present similar barriers to disabled and elderly people.
The same principles, tonal contrast entry and exit, moving handrail and lighting,
as for escalators apply.
There must always be an alternative pedestrian route provided.
Staff and wheelchairs should be available on request to assist people who cannot
use the travelators, and for whom the pedestrian distances are too great unaided.
A free scooter hire service should be considered for large locations, particularly airport terminals.
