f. and 1.22 m to 2.44 m (4-8 ft) for passenger cars.
Passenger and service cars shall not share the same lobby.
Where two or more elevator group lobbies are adjacent, provide
walls or other building features to prevent a free flow of traffic between
those lobbies (to minimize one user from placing calls to both groups).
Elevator lobbies generate noise and must be acoustically isolated
from critical care areas.
All elevator equipment rooms should be electrically and
acoustically isolated to prevent interference with building electronic
equipment and objectionable noises. Elevator equipment rooms shall be
acoustically separated from critical care and occupied rooms.
Hospital type elevator cars shall have interior dimensions that
accommodate a patient bed with attendants. Cars shall be at least 1.73 meters
(5'-8") wide by 2.74 meters deep (9'-0"). Car doors shall be side opening
with a minimum clear opening of 1.22 (4-0") meters wide and 2.13 meters (7-0")
high. In renovations, existing elevators that can accommodate patient beds
used in the facility will not be required to be increased in size. Hospital
type elevator cars Provide protective cab interior blankets. Wall mounted
blankets for interior wall surfaces providing protective coverage from the
finished floor to 300 mm (12") below the cab ceiling.
Transportation systems design will consider traffic demand,
vertical travel distance, mix of traffic type in the areas to be served, and
mode of containerization. Traffic demand and travel distance will determine
equipment type and speed required. Traffic mix and mode of containerization
will determine load capacity, platform size, configuration and door type.
Figure 17.12 illustrates a typical passenger elevator
configuration, and figures 17.13 and 17.14 illustrate the configuration of
typical hospital service elevators. Figure 17.13 is similarly applicable to
typical clinic elevators. All hospital elevators (passenger and service) must
be capable of transporting patient litters.
Front and rear opening hospital service elevators (Figures. 17.15
and 17.16) may be used as swing elevators for both passenger and service
traffic when space or budget restrictions limit use of separate passenger
Types of personnel and materials transactions define the
nature of traffic circulating between various health facility departments.
The following traffic factors may be used to compute traffic volumes for
various traffic types, in lieu of specific direction from the User service.
Pedestrian Traffic Factors.
Assume the number of visitors to inpatient areas to average one
visitor per inpatient bed per day.
