21.3.4.3
Secondary Directory. Smaller, less comprehensive directories
shall be used in less important areas, such as at elevator lobbies, on
upper floors or at secondary entrances.
21.3.4.4
Directional Signs. Once a person has used the directory and
decided the general direction to go, directional signs must guide
individuals through decision points and to their final destination.
Directional signs must also guide a person from their destination back to
their starting point. As with exterior signs, left-pointing arrows shall
be placed at the top, up-pointing arrows next, and right-pointing arrows
at the bottom. All characters and directional arrows should be easily
changeable to provide for future department relocations. When
pictographs are used, the pictograph shall be shown to the left of the
message. Where a floor level designation is used, it shall be at the top
of the sign panel. Include "Staff Only" and "No Entry" signs at
appropriate entrances where only medical staff is authorized.
21.3.4.5
Department Identification Signs. Design signs to identify
activities for individual departments and rooms. Provide large, easy to
read signs over reception counters, check-in counters, information desks,
and departments. Signs shall be either ceiling mounted or affixed to a
soffit directly above the counter. Locate department identification
signs along main corridor paths, rather than within waiting areas, so
they are visible to persons prior to arrival at the department.
Lettering on overhead suspended or projected department identification
signs shall be minimum 75mm. Department identification signs must be
sized such that all lettering is clearly visible to users from the
intended viewing distance. If signs are mounted perpendicular to
corridor walls, assure that emergency exit signs are not obstructed.
Identification signs may also include a pictograph and room designation
on a header panel, to provide added emphasis to the message. To be
effective, the pictograph must be an easily recognizable graphic. The
message would then be placed on the insert panel.
21.3.4.6
Room Identification. All rooms shall be identified with a
permanent message that includes the user room designation in raised
letters and Braille. Use of personal names on interior signs is
discouraged; however, if names are required, they must be provided using
a changeable message strip. Design patient room identification signs to
include the room designation on the header panel, with insert panels for
information signage such as "Oxygen In Use", "Isolation", and "No
Visitors". Consider including designating patient vs. staff toilet room
messages. Include additional blank inserts for staff-defined messages as
may be required due to the unique conditions of a patient. User room
designations and messages are to be left justified on signs, i.e. flush
left.
21.3.4.7
Maintenance Room Numbers. Room number tags shall be included
for every room, space, alcove, closet, toilet, patient room, etc to
assist maintenance staff. These tags shall be approximately 25mm high
with the room number used on the architectural floor plans. Raised
characters are preferred to inscribed characters to prevent obstruction
following door frame painting. The tags shall be installed on the
outside of the room, on the top center of the door frame, or on the
strike side of the door, if neither side is clearly outside. These tags
are not required to be in Braille. Recommend including in the signage
specification.
21.3.4.8
Information, Regulatory and Code Signage. These signs
provide messages that aid in the daily transaction of business and
provide regulations for health and safety. Use these signs to fulfill
