1.3.1 Communication Prior to conducting an evacuation, the following steps should be taken.
(a) The responsible personnel in the building should immediately communicate with the occupants of the elevator car to inform them that:
1) they are safe; .
(2) steps are being taken to evacuate them from the elevator car;
(3) they should stand clear of doors since they may be opened;
(4) they should refrain from smoking.
(b) In communicating with the occupants of the elevator car, the following information should be obtained for guidance in making decisions on actions to be taken in the rescue operation: (1) the number of persons in the elevator car;
(2) whether any of the occupants of the elevator car are ill or injured;
(3) whether the lights are on in the elevator car;
(4) the location of the elevator car in the hoistway, if known. The rescue team should verify that these steps have been taken, and while the rescue operation is in progress, the occupants of the elevator car should continually be kept informed and reassured of their safety.
1.3.2 Assessment of Conditions
It is recognized that the preferred safe practice in evacuating passengers is to move the elevator car to a landing level. The procedures outlined herein do not require the movement of the elevator car by any means other than normal inspection or Phase | operation.
Movement of the elevator car by any other means should only be attempted under the direct supervision of experienced elevator personnel. Before utilizing any of these procedures, ascertain that the mainline disconnect switch is in the “ON” position (closed) and that the emergency stop switch, if the car is so equipped, is in the“RUN” position, not in the “STOP” position.
If the elevator is equipped with firefighters’ service operation, try activating the Phase I lobby key switch to recall the elevator car to the main floor.
If the elevator car is stalled due to a loss of power to the building, and the building has a standby or emergency power source equipped to operate the elevators, it may be possible to run the elevators by turning the emergency recall switch in the main floor lobby to the “ON” position. Use the manual elevator standby power selection switch, if provided, to bring the elevator cars to the main floor, one by one.
If these methods do not work, determine the position of the elevator car and continue with the evacuation procedure that is appropriate:
(a) car at or near landing (see para. 1.3.3);
(b) car within 3 ft (91 4 mm) of landing (see para. 1.3.4);
(c) car more than 3 fi (91 4 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 be that the hoistway door is unlocked, and the hoistway and car doors can be opened by hand. Under these conditions proceed as follows.
(a) Set the mainline disconnect switch for the stalled elevator in the “OFF” position.
(b) Open the doors by hand.
(c) Enter the elevator car and set the emergency stop switch, if the car is so equipped, in the “STOP” position.
(d) Assist the passengers in leaving the elevator car, one at a time. If the car is not level with the landing, make sure that the passengers do not trip or fall while leaving the car.
1.3.4 Procedure With Car Within 3 ft (914 mm) of Landing When the hoistway doors are not unlocked and the elevator car floor (platform) is within 3 ft (91 4 mm) of the landing level [see Fig. 1 .3.4(a)], the following methods of removing the passengers should be used.
