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
