ASME A17.4:2015 pdf free download – Guide for Emergency Personnel
Movement of the elevator car by any other means should be attempted only 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 as specified in 1.3.3 through 1.3.5 and continue with the evacuation procedure that is appropriate.
1.3.3 Procedure With Car at or Near a 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. Lockout/tagout the mainline disconnect switch.
(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” or “OFF” position. If the car is equipped with a key-operated, in-car stop switch, use the key, if available, to turn the switch to the “OFF” 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.
When the hoistway doors are not unlocked and the elevator car floor (platform) is within 3 ft (914 mm) of the landing level [see Fig. 1.3.4(a)], the following methods of removing the passengers should be used:
(a) Opening Doors From Landing or From Inside Elevator Car
(1) Set the mainline disconnect switch for the stalled elevator in the “OFF” position. Lockout/tagout the mainline disconnect switch.
(2) Unlock the hoistway door at the floor nearest to the stalled elevator car by means of the hoistway door-unlocking device (elevator door interlock release key), if provided, and open the hoistway and car doors by hand [see Fig. 1.3.4(b)]. If hoistway door-unlocking devices are not provided, it may be possible on some installations for a passenger to manually open the car and hoistway doors from within the elevator car [see Figs. 1.3.4(c) and 1.3.4(d)]. If this is not possible, see 1.3.4(b).
(3) A member of the rescue party should then enter the elevator car and place the emergency stop switch, if the car is so equipped, in the “STOP” or “OFF” position. If the stalled car is equipped with a key-operated, in-car stop switch, use the key, if available, to turn the switch to the “OFF” position. Where the in-car stop switch is located behind a locked panel, unlock the panel and activate the stop switch.
