If the elevator car is stalled due to a loss of power to the building, and tho 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 “ONe 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 (914 mm) of landing (see para. 1.3.41;
(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 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) The mainline disconnect switches in the machine room for the stalled elevator and the adjacent elevators (if the stalled elevator car is located in a multiple hoistway) should be set in the 0FF position.
(2) The rescue team should open the hoistway door at the nearest landing or an emergency access door, where provided, above the stalled elevator car top. This entry can be made by the use of the hoistway door unlocking device, the emergency-door key, or by forcing open the hoistway doors.
(3) A ladder with nonskid feet should be lowered to the elevator car top and securely positioned on the elevator car top. This ladder should be of sufficient length to extend at least 3 ft (914 mm) above the landing floor bee Fig. 1.3.5(a)l.
(4) One member of the rescue team, wearing a safety belt and properly tied off to a secured lifeline, should descend to the top of the stalled elevator car. A second ladder should be lowered through the top emergency exit and positioned between the elevator car floor and car top. This second ladder should be of sufficient length to extend at least 3 ft (914 mm) above the car top.
