FOREWORD Since 1921, The Am
9、erican Society of Mechanical Engineers (ASME) has developed and published safety codes and standards for elevators, escalators, and related equipment. In the 1960s, a demand from many building owners, lessees, and operating managements emphasized a need for a guide for the evacuation of passengers f
10、rom stalled elevator cars. To meet this need relating to safety, the A17 Executive Committee initiated a project of study that resulted in the development of the A17 Guide for the Evacuation of Passengers From Stalled Elevator Cars. This first edition was endorsed by the A17 Standards Committee in D
11、ecember 1972, and was published in 1973. Since the publication of the first edition of the Guide, changes to the A17.1 Safety Code for Elevators and Escalators prompted the ASME A17 Committee to revise the Guide and keep it updated with new editions. The procedures contained in this Guide are based
12、on past or current A17.1 editions and do not take into account any local jurisdictional revisions that may have been made.

17、evator operation at every building within their jurisdiction. In training personnel, advantage should be taken of the experience and expertise, which may be provided by the elevator maintenance organization servicing the elevator equipment. Rescue 2 ASME A17.4-1999 1.2.2-1.3.2 drills should be plann
18、ed to simulate various emergency conditions and should be conducted to determine the effectiveness of the rescue operation and organization. On observation elevators, considerable preplanning may be necessary since condi- tions vary. Written instructions on the stepsto be taken to effect a rescue sh
19、ould be furnished to all personnel designated and trained to perform rescue duties. These instructions must also be in a location known and accessible to the rescue team, where .they can be readily referred to during an evacuation, if necessary. These instructions should include the telephone number
20、s of persons or organizations to be contacted for assistance, e.g., elevator maintenance personnel. SECTION 1.3 EVACUATION PROCEDURES 1.3.1 Communication Prior to conducting an evacuation, the following steps should be taken. (a) The responsible personnel in the building should immediately communica
21、te with the occupants of the elevator car to inform them that: (71 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 elev
22、ator car, the following information should be obtained for guidance in making decisions on actions to be taken in the rescue operation: (7) 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 elevato
23、r 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
24、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 I operation. Movement of the elev
25、ator 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,
26、 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. 3 1.3.2-1.3.3 ASME A17.4-1999 J 9 FIG. 1.3.3 CAR AT OR NEAR LANDING If the elevator car is
27、 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 po
28、wer 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
29、 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 be that the hoistway door is unlocked, and the hoistway and car doors can be op
30、ened 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
31、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. 4 ASME A17.4-1999 1.3.4 FIG. 1.3.4(a) E L u CAR WITHIN 3 ft OF LANDING 1.3.4 Procedure With Car Within 3 ft (914 mml of Landing Wh
32、en 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 (7) Set the mainline disconnect swi
33、tch for the stalled elevator in the “OFF“ position. (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)l. If hois
34、tway 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)l. If this is not possible, see para. 1.3.4( b). (3) A member of the rescue party should ente
35、r the elevator car and place the emergency stop switch, if the car is so equipped, in the “STOP“ position. (4) 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
36、be used for safe removal. Precautions should be taken to guard any hoistway opening below the elevator car floor (platform) when the car is above the landing see Fig. 1.3.4(e)l. ib) Opening Doors From Adjacent Elevator Car. When a hoistway door unlocking device (elevator door interlock release key)
37、is not provided, or the doors cannot be opened from within the elevator car by the passengers, and an adjacent car 5 1.3.4 ASME A17.4-1999 FIG. 1.3.4(b) USE OF HOISTWAY DOOR UNLOCKING DEVICE is operable, the following procedures should be utilized. (7) Take an adjacent elevator car to the floor clos
38、est to the stalled car and open its doors. (2) Set the mainline disconnect switches for both the stalled elevator and the rescue elevator in the “OFF“ position. Also, place the emergency stop switch of the rescue elevator car, if the car is so equipped, in the “STOP“ position. (3) By extending a pol
39、e through the opening between the car and hoistway doors of the rescue elevator car, it may be possible 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
40、 is still in service. If this is not possible, see para. 1.3.4(c). (4) A member of the rescue team should then enter the stalled elevator car and set the emergency stop switch, if the car is so equipped, in the “STOP“ position. (5) The passengers should then be assisted from the stalled elevator car
41、, 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. 1.3.4(e)l. (
42、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 6 ASME A17.4-1999 1.3.4 FIG. 1.3.4(c) OPENING OF CAR DOOR BY HAND (Not Possible on Some Elevators) FIG. 1.3.4(d) OPENING HOISTWAY DOOR BY HAND (No
43、t Possible on Some Elevators) in the same hoistway is not available, the hoistway door at the floor nearest to the stalled elevator car can be forcibly opened. Proceed as follows. (7) Set the mainline disconnect switch for the stalled elevator in the “OFF” position. (2) Open the doors with the use o
44、f the forcible entry tool. It should be used at the top of the doors where the interlock is located to minimize damage to the doors and to allow for quicker return to normal service see Fig. 1.3.4(f)l. (3) A member of the rescue team should enter the elevator car and set the emergency stop switch, i
45、f the car is so equipped, in the “STOP” position. (4) 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
46、guard any hoistway opening below the car floor (platform) when the elevator car is above the landing see Fig. 1.3.4(e)l. 7 1.3.5 ASME A17.4-1999 FIG. 1.3.4(e) GUARDING OF HOISTWAY OPENING BELOW THE CAR 1.3.5 Procedure With Car More Than 3 ft (914 mm) From Landing When an elevator car is stalled so t
47、hat 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 (platform) and landing level creates a danger due to the possibility that a passenger may fall i
48、nto the hoistway. In addition, it is inadvisable to remove passengers through the elevator door opening when the car floor (platform) is more than about 3 ft (914 mm) below the landing level since the reduced opening clearance makes exiting too difficult. The recommended methods for removing the pas
49、sengers under these conditions are as follows. (a) Removal Through Top Emergency Exit CAUTION Do not use the top emergency exit on an elevator in an unenclosed hoistway. New elevators in unenclosed hoistways will not have top emergency exits. If exiting 8 ASME A17.4-1999 1.3.5 FIG. 1.3.4(f) PROPER USE OF FORCIBLE ENTRY TOOL through the elevator entrance is not possible, have experienced elevator personnel move the elevator car to a landing level.
