1.3.2 Assessment of Conditions
lt is recognized that the preferred safe practice in evacuating passengers is tomove the elevator car to a landing level. The procedures outlined herein do notrequire the movement of the elevator car by any means other than normal inspectionor Phase l operation. Movement of the elevator car by any other means shouldonly be attempted under the direct supervision of experienced elevator personnel.Before utilizing any of these procedures,ascertain that the mainline disconnectswitch is in the”ON” position (closed) and that the emergency stop switch, if thecar is so equipped, is in the“RUN”” position,not in the “STOP” position.
lf the elevator is equipped with firefighters’ service operation, try activating thePhase ! lobby key switch to recall the elevator car to the main floor.
lf the elevator car is stalled due to a loss of power to the building, and thebuilding has a standby or emergency power source equipped to operate theelevators, it may be possible to run the elevators by turning the emergency recallswitch in the main floor lobby to the“ON” position. Use the manual elevatorstandby power selection switch, if provided, to bring the elevator cars to the mainfloor,one by one.
lf these methods do not work,determine the position of the elevator car andcontinue with the evacuation procedure that is appropriate;
(a)car at or near landing isee para. 1.3.3);
(b)car within 3 ft (914 mm) of landing (see para. 1.3.4》;
(c) car more than 3 ft (914 mm) from landing (see para. 1.3.5).
1.3.3 Procedure With Car at or Near Landing
When an elevator car is located at or near a landing (see Fig. 1.3.3),it may bethat the hoistway door is unlocked, and the hoistway and car doors can be openedby hand. Under these conditions proceed as follows.
(a)Set the mainline disconnect switch for the stalled elevator in the“OFF”position.
