Identifying access problems
How many problems of accessibility
can occur in a short distance? In the example illustrated
below the problems include the following:
a ramp that is too steep
a rough surface with inset bricks which has tripping
hazards
black bollards, which are difficult to see
tinted glass, which causes confusing reflections on
the entrance doors
doors which are heavy to open and where each leaf is
too narrow
an inner set of doors which is so close to the outer
doors that, for many people, both sets have to be open at
the same time
a reception desk that is too high
background noise, which makes it difficult to hear
the receptionist
a combination of low levels of illumination and glare,
which makes it difficult to lip-read when talking to the receptionist
|
This steep ramp features tripping
hazards due to the irregular surface and leads towards
black bollards which are difficult to see |
|
The black bollards contribute
to the confusing reflections on the glass of the entrance
doors |
If the reception staff were
not very responsive and helpful, these problems would be much
more apparent.
This example illustrates that
accessibility and communication are the key considerations
in the design or appraisal of an entrance and reception area.
These may have to be balanced by the needs for control of
access and for security. Communication begins with the street
names, sign-posting and signing systems which enable people
to find the entrance. It is surprising how often an access
audit identifies problems in finding the route to the entrance
when the staff and regular visitors may be quite unaware of
these problems.
Tactile paving may be required
on the routes towards the premises. Recognising that this
is often over-used and can cause problems for many people
with disabilities, BS 8300 recommends that tactile paving
'should be used sparingly and only after consultation with
groups representing visually impaired people'.

groups'

Gaining entry
At the entrance, any changes
of level should be achieved by sloping access and with steps
or, if necessary, a lift capable of carrying a wheelchair
user or person with limited mobility. It is not usually adequate
to provide a stairlift, which can only compound the problems
if wheelchair users have to transfer to the stairlift (see
photo below). BS 8300 points out that oval handrails, with
a broad horizontal face, may be preferable to circular handrails
because these give better support to the hand and forearm.
In exposed situations, nylon covered handrails are warmer
to the touch than stainless steel.
|
Unlike
a platform lift, this stairlift is useless for anyone
who needs a wheelchair |
If the entrance is controlled,
the visitor will need to ring for authorisation to enter.
In this case, the call button should be clearly identifiable,
and at a height of not more than 1200mm, for people who are
partially sighted, short in stature or in a wheelchair. For
those who are deaf or have impaired hearing there should be
a visual indication (for example LED) to show that the door
is open - consider how frequently, with a background of traffic
noise, it is impossible for anyone to hear the verbal response
on an entry control system.
|
Recent 'improvements': the
shiny metal plate to the right of the door is illegible,
the doorbell is too high, the ramp is about 1 in 6, there
is no level landing and no handrail.
Because the door opens outwards visitors tend to step
backwards off the edge of the ramp |
The lobby area
A canopy or recessed porch
can enable people to stop under cover before negotiating the
entrance doors. The entrance doors should be easy to open
manually or have mechanical assistance, for example automatic
or semi-automatic sliding or swing doors. A lobby, with outer
and inner doors, may be used to reduce draughts in the entrance
area but the airlock arrangement will be effective only if
one set opens in and the other opens out. The clear space
between the doors should be about 1600 mm to enable a wheelchair
to manoeuvre. Any door-opening furniture should preferably
have lever handles - these are not only easier to grip than
round handles but can be used with a closed fist, benefiting
those with a weak grip or arthritis.

Two pairs of automatic sliding
doors provide easy access for everyone at a day centre
for people with disabilities.

firmer matting surface |
Internal finishes
Inside the entrance doors,
there should generally be a recessed mat which is firm (not
soft coconut matting) and which cleans shoes and wheelchair
wheels as they enter. It is particularly important that on
a wet day the internal floor does not become slippery as water
drips off raincoats and umbrellas. Smooth and shiny floor
surfaces, for example vinyl or marble, can become very slippery
and a real hazard for everyone, particularly for people with
walking difficulties.
Lighting levels in the entrance
area should be intermediate between the internal and external
levels of illumination, typically about 200 lux, so as to
enable the eyes of visitors to adjust when going in or out.
For many people who are elderly or have impaired vision, it
is essential to avoid glare both from sunlight and from artificial
lighting. A covered porch is a simple and self-regulating
way of achieving appropriate illumination at an entrance.
|
Highly polished floors can
cause problems of glare for many people and become dangerously
slippery when wet. The solution may be to use a different
floor polish

Once inside, the route to the reception
or information desk should be clearly apparent.
At this stage in the journey, where there can be a conflict
between security and accessibility, people with disabilities
should be at no more of a disadvantage than anyone else. For
example, if the desk is high, there should be a surface at
a height of about 750-850 mm and this should be located at
the most convenient part of the desk and not, as often occurs,
hidden away at the side. The options for reception desks include:
a) open desks with low security
risks - good lighting can assist direct
communication for everyone, particularly when people need
to lip-read
b) desks closed with security
glass - microphones or induction loops are then necessary
and good lighting continues to be important

Although the knee space under
the lower shelf is too shallow, this reception desk is
welcoming for everyone, including visitors and staff with
wheelchairs |
In many reception areas, background
noise of music or water features can make it very difficult
to communicate at the reception desk. A classic example of
getting it wrong occurs in many large buildings where, in
order to improve accessibility for people with disabilities,
the entrance is fitted with sliding doors.
|
Accessibility with security:
the high reception desk with a curved base protects staff
from violent clients; the low desk would be suitable for
both staff and clients with wheelchairs (if the plants
were moved!). Induction loops have been installed |
The result can be that, at
busy entrances, the doors are open for so much of the time
that there are cold draughts at the reception desk. Fan heaters
are then installed to keep the reception staff warm, with
the result that the noise level makes normal verbal communication
almost impossible!
Waiting around
The waiting areas should have
some seats with arms, space for wheelchair users, adequate
but glare-free lighting, good contrasts of colour and tone
and an appropriate way of informing people that the person
they have come to see is available. The most natural way to
do this is by someone walking to greet them. In doctors' surgeries
and hospitals, where less personal methods may be required,
vibrating pagers can be discrete and appropriate for many
people.
New technology
Microtechnology provides increasingly
sophisticated methods for assisting people with disabilities.
This includes providing information about their progress in
a queue, the time when they are called and the routes which
they should follow. Keyless entry systems can then unlock
and open selected doors, providing unobstructed routes as
people proceed towards their destination. Computer technology
can also assist people with visual impairments by enlarging
documents on screen.

Computer technology can assist
people with impaired vision to read documents such as
BS 8300 which is published in ten point. |
