ACCESS INTO BUILDINGS
OTHER
THAN
DWELLINGS
Objectives
1 The aim for all
new buildings is
for the principal entrance or
entrances
and any main staff entrance, and
any
lobbies, to be
accessible.
2 Where it is not
possible, e.g. in an
existing building, for the principal
or
main staff entrance or entrances to
be
accessible, an alternative
accessible
entrance should be
provided.
3 It is important
to reduce the risks
to people when entering the
building.
Accessible
entrances
Design
considerations
4 Steeply sloping
or restricted sites
sometimes make it impossible for
the
principal or main staff entrance to
be
accessible, in which case an
alternative
accessible entrance may be
necessary.
5 Accessible
entrances should be
clearly sign-posted and
easily
recognisable. Any structural
elements,
for example supports for a canopy,
are
useful in identifying the entrance,
but
should not present a
hazard.
6 The route from
the exterior across
the threshold should provide
weather
protection, and not present a barrier
for
wheelchair users or a trip hazard
for
other people. A level threshold
is
preferred, especially for doors
in
frequent use.
Note: Guidance on
sign-posting is
given in BS 8300, ‘Inclusive
Mobility’
and the ‘Sign Design
Guide’.
Provisions
7 Accessible
entrances will satisfy
Requirement M1 or M2
if:
a. they are clearly
sign-posted,
incorporating the International
Symbol
of Access, from the edge of the
site,
and from the principal entrance (if
this
is not
accessible);
b. they are easily identified
among
the other elements of the building
and
the immediate environment, e.g.
by
lighting and/or visual
contrast;
c. any structural supports at
the
entrance do not present a hazard
for
visually impaired
people;
d. there is a level landing at
least
1500 x 1500mm, clear of any
door
swings, immediately in front of
the
entrance and of a material that
does
not impede the movement
of
wheelchairs;
e. the threshold is level or, if a
raised
threshold is unavoidable, it has a
total
height of not more than 15mm,
a
minimum number of upstands
and
slopes, with any upstands higher
than
5mm chamfered or
rounded;
f. any door entry systems
are
accessible to deaf and hard of
hearing
people, and people who cannot
speak;
g. weather protection is provided
at
manual non-powered entrance
doors;
h. internal floor surfaces adjacent
to
the threshold are of materials that
do
not impede the movement
of
wheelchairs, e.g. not coir matting,
and
changes in floor materials do not
create
a potential trip
hazard;
i. where mat wells are provided,
the
surface of the mat is level with
the
surface of the adjacent floor
finish;
j. where provided as an
alternative
accessible entrance, an
accessible
internal route is provided to the
spaces
served by the principal or main
staff
entrances.
Doors to accessible
entrances
Design
considerations
8 Doors to the
principal, or
alternative accessible, entrance
should
be accessible to all,
particularly
wheelchair users and people
with
limited physical dexterity.
Entrance
doors may be manually
operated
without powered assistance, or
poweroperated
under manual or
automatic
control. Entrance doors should
be
capable of being held closed when
not
in use.
2.9 A non-powered
manually operated
entrance door, fitted with a
self-closing
device capable of closing the
door
against wind forces and the
resistance
of draught seals, is unlikely to
be
openable by many people,
particularly
those who are wheelchair users or
who
have limited
strength.
2.10 A powered door
opening and
closing system, either
manually
controlled or automatically operated
by
sensors, is the most
satisfactory
solution for most people. An
automatic
sliding door arrangement is
particularly
beneficial as it avoids the
risks
associated with automatic swing
doors
and its use can make it possible
to
reduce the length of any
entrance
lobby.
2.11 Once open, all
doors to
accessible entrances should be
wide
enough to allow unrestricted
passage
for a variety of users,
including
wheelchair users, people
carrying
luggage, people with assistance
dogs,
and parents with pushchairs and
small
children. It should be noted that
double
buggies are wider than wheelchairs
and
that, where relevant to the
building
type, this should be borne in
mind
when determining an
appropriate
effective clear width for an
entrance
door. There may be circumstances
in
existing buildings where it is
not
practicable or cost-effective to
adopt
the preferred effective clear widths
for
new buildings. In such cases,
the
argument for adopting the
minimum
dimensions for existing
buildings
should be made in the
Access
Statement.
2.12 People should
be able to see
other people approaching from
the
opposite direction, thereby
allowing
sufficient reaction time for both
parties
to avoid a collision. Any exceptions
for
reasons of privacy or security
should
be argued in the Access
Statement.
Provisions
2.13 Doors to
accessible entrances will
satisfy Requirement M1 or M2
if:
a. where required to be
self-closing,
a power operated door opening
and
closing system is used when
through
calculation and experience it
appears
that it will not be possible otherwise
for
a person to open the door using
a
force no greater than 20N at
the
leading edge;
b. the effective clear width through
a
single leaf door, or one leaf of a
double
leaf door, is in accordance with Table
2,
and the rules for measurement are
in
accordance with Diagram
9;
c. unless it can be argued
otherwise
in the Access Statement, e.g.
for
reasons of security, door leaves,
and
side panels wider than 450mm,
have
vision panels towards the leading
edge
of the door whose vertical
dimensions
include at least the minimum zone,
or
zones, of visibility between 500mm
and
1500mm from the floor, if
necessary
interrupted between 800mm
and
1150mm above the floor, e.g.
to
accommodate an
intermediate
horizontal rail .
