Elevator Mechanic Practice Exam

The correct answer involves a fundamental practice of safety when working on elevators, which is to implement lockout/tagout (LOTO) procedures and block open the elevator doors. This procedure is crucial as it ensures that the elevator cannot be inadvertently powered on while maintenance is being performed, protecting the technician from injury. Blocking open the doors also prevents the risk of accidentally closing them on a person or equipment during maintenance. While it is essential for all passengers to exit the elevator and testing emergency features are useful safety measures, they are not as comprehensive as LOTO when ensuring the safety of the mechanic working on the elevator. Performing a hazard analysis is also important but typically comes earlier in the process, before the specific safety measures like LOTO are put in place. Thus, implementing LOTO is the most critical step before initiating work on an elevator.
