Elevator Mechanic Practice Exam

What must be done before entering an elevator hoistway for maintenance?

1. Turn off the elevator power supply

2. Notify the building management

3. Engage the emergency brake

4. Secure the out-of-service sign on each landing

The correct answer is: Turn off the elevator power supply

Turning off the elevator power supply is a crucial safety step before entering the hoistway for maintenance. This action ensures that the elevator cannot be accidentally activated while maintenance work is being conducted, thereby protecting the technician from potential injury due to unexpected movement of the elevator car or other components. Safety protocols require this step to minimize risks associated with electrical hazards and mechanical movements. While notifying building management, engaging the emergency brake, and securing an out-of-service sign are all important safety measures to consider when maintaining an elevator, the immediate necessity is to remove the power supply to eliminate the risk of the elevator operating during maintenance. This prioritization underscores the importance of establishing a safe working environment and adhering strictly to safety guidelines.
