Study Notes

Elevator Rescue Procedures

Elevator rescues are categorized into Non-Emergency (no immediate danger) and True Emergency (imminent danger).

Non-Emergency Procedures

Passengers in a stopped elevator generally need reassurance and assistance from TFD personnel.
Steps include contacting an elevator mechanic and activating the fire service feature Phase I to potentially bring the elevator down.
If Phase I does not work, wait for the elevator mechanic for further action.

True Emergency Procedures

In imminent danger situations, involve the Rescue Task Force for specialized equipment.
Establish verbal contact with trapped passengers to provide reassurance and assess any medical emergencies.
There are two types of elevators: Traction (cabled with a hoist motor) and Hydraulic (operated by hydraulic fluid).

Door Mechanisms

Door Restrictors: Prevent the opening of elevator doors between floors; can be mechanical or electromechanical.
Door Operators: Typically open by pulling; if limited movement occurs, check for door restrictors.

Steps for True Emergency Rescues

Step 1: Lock out power by disconnecting power in the elevator mechanical room before any other actions.
Step 2: Make contact with passengers, reassure them, and check for medical emergencies.
Step 3: Decide on the rescue method based on elevator type and accessibility.

Rescue Techniques

Car Top Exit (Step 4a): Access top of the car using a ladder after opening the hall door and car top exit.
Door Opening (Step 4b): Open hall and car doors to extract passengers; be cautious of door restrictors.
Leap Frogging (Step 4c): Required when limited access exists; involves unlocking doors from above or below using an elevator pole.
Manual Lowering (Step 4d - hydraulic only): Safest for hydraulic elevators; requires opening valves and ensuring clear car doors before assisting passengers.

Important Notes

Ensure that any manual lowering of a hydraulic elevator is done safely with no tools typically required; in case of issues, wait for the mechanic.
Effective communication and reassurance to trapped passengers are critical throughout rescue procedures.
