EXTERIOR ENTRANCES AND PLATFORMS:
8.1
Provide a non-combustible canopy over the main entrance. The
canopy shall extend 600 mm (2 feet) beyond the curb line to
protect patients from inclement weather. To reduce the size and
cost of the canopy, locate the curb line near the entrance if
compatible with other design considerations. At this main entrance
provide an "air lock" consisting of a vestibule formed by
automatically operated doors placed not less than 6.3 m (21 feet)
apart. Automatic sliding doors are preferred, but if swinging
doors are used, both the inner and outer doors shall swing
outward. Provide break-away type automatic doors that can be
manually operated during a power failure.
8.2
All platforms, ramps and stairs adjacent to entrances shall have
non-slip surfaces.
8.3
All entrances and exits at grade must be accessible to and usable
by persons with disabilities, that is, level or provided with
ramps, and free of steps or other obstructions.
8.4.
LOADING PLATFORM: If a loading platform is required, it shall be
at least 150 mm (6 inches) above the access-drive paving, but may
be as high as 1200 mm (4 feet), depending on the delivery vehicles
to be used. If delivery vehicles have varying dock requirements,
or are unknown, then a scissors lift should be installed. The
platform shall have a minimum depth of 2.4 m (8 feet), 3.9 m (13
feet) if a scissors lift is used, and shall be covered by a non-
combustible canopy with a minimum clearance of 4.7 m (15'6") above
the platform.
9.
DOORS:

Provide solid core wood or hollow metal interior doors. Wood is
preferred, except for locations where metal is required for
functional reasons. Provide metal door frames. Follow VA Program
Guide PG-18-14, Room Finishes, Door and Hardware Schedule, for
sizes, types, and symbols of doors.
All corridor-to-corridor doors shall have 0.06 m2 (100 sq. in.)
9.2
glass vision panels and shall swing in opposite directions from
each other. Doors in fire partitions and smoke barriers shall
have fire rated glazing vision panels and be held open with
electromagnetic holders, except doors which should remain closed
for functional reasons.
