    Study Notes

    Elevator Rescues

    • Elevator rescues can be divided into two categories: Non-Emergency and True-Emergency
    • Non-Emergency: stopped/stalled elevator cars with no immediate danger to passengers, require reassurance and low/no risk techniques, and elevator mechanic assistance
    • True-Emergency: stopped/stalled elevator cars with passengers who have a true emergency (e.g., medical problems, fires, hazardous materials, terrorism), require specialized tools and equipment, and Rescue Task Force assistance

    Non-Emergency Elevator Rescue

    • Activate fire service feature Phase I in the bank of elevators to override the problem with the elevator’s automatic operation and bring the elevator down to the designated level
    • If all elevators return to the designated level except one, identify the elevator with the victims
    • Wait for an elevator mechanic to assist

    True Emergency Elevator Rescue

    • Two types of elevators: Traction (cabled) and Hydraulic
    • Rescue procedure is the same for both types, with an additional option for Hydraulic elevators (manual lowering)
    • Rescue steps:
      • Remove power at the disconnect (Lock out/Tag out)
      • Make verbal contact with passengers, assure them they are OK, and determine if there are any medical emergencies
      • Determine the type of rescue to be performed (car top emergency exit, through door opening, "leap frogging" or "polling", or manual lowering)

    Elevator Rescue Procedures

    Car Top Emergency Exit

    • Open hall door with hoistway access key, prop open
    • Open car top exit to gain access to inside of the car
    • Remove trapped passengers via ladder lowered into the car

    Through Door Opening

    • Open hall door with hoistway access key, prop open
    • Open car doors by pulling car door clutch or rolling door operator pulleys
    • Be aware of door restrictors and door operators

    Leap Frogging (Polling)

    • Necessary when there is limited hoistway access
    • Rescue steps involve accessing the elevator from the top and bottom floors, using an elevator pole or fire department pike pole to unlock hall doors

    Manual Lowering (Hydraulic Only)

    • Safest way to rescue passengers from a hydraulic elevator
    • Steps:
      • Advise passengers to stay clear of car doors
      • Make sure car doors are completely closed
      • Open manual lowering valve until oil stops draining back into tank
      • Close valve
      • Open hall doors with hoistway access key
      • Push open car doors by grabbing car door clutch
      • Allow passengers to step up and out of car

    Important Notes

    • Door restrictors: mechanical or electromechanical devices that prevent the opening of car doors between floors
    • Door operators: can roll open by pulling on clutch, sometimes straight armed with doors in closed position, and arm must be unlocked
