What is the first thing you must do before performing any service on an elevator?

1. Notify the supervisor

2. Place barricades at the upper and lower ends

3. Test the elevator for functionality

4. Check the electrical supply

The correct answer is: Place barricades at the upper and lower ends

Before performing any service on an elevator, the first priority is to ensure the safety of both the technicians and any passengers who may come into the area. Placing barricades at both the upper and lower ends of the elevator shaft is crucial as it establishes a clear zone where no one is allowed to enter. This action prevents unauthorized access and protects individuals from potential hazards associated with elevator maintenance, such as unexpected movements or electrical shocks. Setting up these barricades helps to ensure a controlled environment where work can be done safely. Additionally, it communicates to other personnel or bystanders that maintenance is taking place, thus minimizing the risk of accidents or injuries. This safety measure is fundamental in maintaining a secure work site before any further actions are taken, such as notifying a supervisor or testing the elevator for functionality.
