In elevator rescues, which action should be taken to minimize risk to responders?

• A. Open hoistway doors using elevator key
• B. Shut off power to the elevator
• C. Enter the shaft wearing harnesses
• D. Direct occupants to force the door open

Answer: (B)

In elevator rescues, the first priority is to control the energy sources so the car and hoist aren’t able to move or unexpectedly energize. Shutting off power to the elevator achieves that by isolating the system from the electrical supply. When power is off, the car can’t start moving, doors won’t operate unpredictably, and the hoist machinery is de-energized, which dramatically lowers the risk of responders being struck by a moving car or exposed to electrical hazards. This creates a safer, more stable environment to assess the situation, position equipment, and carry out the rescue. Opening hoistway doors with a key while power is on can still allow dangerous movement or door operation, making it riskier. Entering the shaft with harnesses is a necessary safety measure only after the area is secured and power is off, and it involves additional training and precautions. Direct occupants to force the door open is unsafe; door interlocks and proper procedures must be followed to avoid injury or entrapment. Shutting off power first establishes a safe foundation for any rescue action.
