(3) By extending a poling tool (pike pole) through the opening between the
car and hoistway doors of the rescue elevator car, it may be possible on most types of elevator installations to engage the interlock roller of the stalled elevator car so that its doors can be opened by hand. When using this method, be careful not to extend the pole into the hoistway of any elevator that Is still in service. If this is not possible, see 1.3.4(c).
(4) A member of the rescue team should then enter the stalled elevator car
and set the emergency stop switch, it 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. Where the in-car stop switch is located behind a locked panel, unlock the panel and place the stop switch in the OFF position.
(5) The passengers should then be assisted from the stalled elevator car, one at a time, by rescue personnel located both in the car and on the landing. A sturdy stepladder or footstool should be used for safe removal. Precautions should be taken to guard any hoistway opening below the car floor (platform) when the elevator car is above the landing (see Fig. 1.3.41e)I. A ladder, backboard, basket stretcher, or solid piece of furniture can be used for this purpose.
(C) Opening Doors With Forcible Entry Tool. Where the hoistway doors cannot be unlocked by an unlocking device or by other means, and an adjacent elevator in the same hoisiway is not available, the hoistway door at the floor nearest to the stalled elevator car can be forcibly opened. Proceed as follows:
(1) Set the mainline disconnect switch for the stalled elevator in the HOFF” position. Lockout/tagout the mainline disconnect switch.
(2) Open the doors with the use of the forcible entry tool. For most newer elevators with center-opening doors, the forcible entry tool should be used at the top of the door where the doors meet; for those with side.opening doors, the tool should be used on the side the door closes into. This results in quicker release of the passengers and minimizes the overall damage so the elevator can be returned to service more quickly (see Fig. 1.3.4(f)(.
(3) Some older elevators have a broken arm interlock and nothing at the top closing part of the door. It may be possible to check this at the lowest landing or on adlacent cars. In this situation, the forcible entry tool should be used at the approximate level where the broken arm attaches to the door, about center from the top to bottom where center-opening doors meet or where side-opening doors close, The arms usually do not conveniently “break” but continue bending as the door Is forced open.
(4) A member of the rescue team should enter the elevator car and set the emergency stop switch, if the car is so equipped, in the STOP” or “0FF” 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 HOFF position. Where the in-car stop switch is located behind a locked panel, unlock the panel and activate the stop switch.
(5) The passengers should then be assisted from the stalled elevator car, one at a time, by rescue personnel located both in the car and on the landing. A sturdy stepladder or footstool should be used for safe removal. Precautions should be taken 10 guard any hoistway opening below the car floor Iplatform when the elevator car is above the landing Isee Fig. 1.3.4(e)). Again, a ladder, backboard, basket stretcher, or solid piece of furniture can be used for this purpose.
1.3.5 Procedure With Car More Than 3 ft 914 mm) From Landing
When an elevator car is stalled so that the car floor (platform) is more than 3 ft (914 mm) above a landing level, it is inadvisable to remove the passengers through the elevator door opening, as the excessive distance between the car floor.
