Prior to attempting any rescue, it is imperative that the rescue team has the proper tools and equipment ready for use. It is equally important that they be trained in the proper use of the tools and equipment. Some of the tools and equipment that may be necessary to make a safe rescue are (see Fig. 1.2.1)
(a) short extension ladder (when using the top emergency exit, a short extension ladder may be helpful in assisting passengers going over the crosshead and for reaching the floor above the car)
(b) collapsible or folding ladder
(c) hoistway door-unlocking devices (elevator door interlock release keys)
(d) two-way radios or portable radios
(e) personnel fall arrest system
(I lifelines
(g) forcible entry tools
(h) flashlights
(I) lockout/tagout equipment
(I) tool for poling (pike pole)
1.2.2 Training and Instruction
The rescue team should be given training in the proper procedures for evacuating passengers as required by ASME A17.1/CSA B44, requirement 8.6.11.5.4 to prepare them for actual emergency situations that may arise in the elevator operation at every building within their jurisdiction. In training personnel, advantage should be taken of the experience and expertise that may be provided by the elevator maintenance organization servicing the elevator equipment. Rescue drills should be planned to simulate various emergency conditions and should be conducted to determine the effectiveness of the rescue operation and organization. On observation elevators and elevators with nonenclosed hoistways, considerable preplanning may be necessary since conditions vary.
Written instructions on the steps to be taken to affect a rescue should 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 numbers of persons or organizations to be contacted for assistance, e.g., elevator maintenance personnel. The keys necessary for elevator evacuation are required by ASME A17.1/CSA B44 to be available to the rescue team. All required keys should be permanently labeled for function.
1.2.3 LockoutlTagout Procedures
Whenever persons are being assisted from a stalled elevator car, adherence to strict lockoutltagout procedures must be followed. The mainline disconnect switch must be turned to the “OFF” position and a lock and tag installed on the disconnect switch in order to prevent anyone from turning the switch to the “ON” position. The mainline disconnect switch is typically located in the elevator machine room when a machine room is provided.

1.2.4 Door Restrictors (Restricted Door Operation)
Many elevator car and/or landing doors are equipped with door restrictors to prevent opening of the car doors or landing doors from inside the car when the car is outside the unlocking zone. These devices are required by ASME A17.1/CSA B and ASME A17.3 to be installed in such a manner that the doors can be opened from outside the car without special tools. Emergency personnel should become familiar with how these devices can be opened from the landing before an actual emergency occurs.
1.3.1 Communication
Prior to conducting an evacuation, the following steps should be taken:
(a) The responsible personnel in the building should immediately be stationed outside of the stalled elevator and 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
(5) they should not attempt to exit the car
(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 have an immediate medical concern
(3) whether the lights are on in the elevator car
(4) the location of the elevator car in the hoistway, if known
(C) One member of the rescue team should be stationed at the location of the elevator mainline disconnect to open or close the mainline disconnect switch as required by the evacuation team. Two-way communication should be maintained between these team members.
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.ASME A17.4 pdf download.
