CWEA Maintenance Technologist Practice Test

Which of the following actions should be taken before working on controls that may disrupt plant operations?

1. Notify all personnel in the area

2. Have an operator present

3. Conduct a risk assessment

4. Power down all machinery

The correct answer is: Have an operator present

Having an operator present before working on controls that may disrupt plant operations is crucial for several reasons. The operator possesses vital knowledge and experience relating to the specific equipment and processes being operated. Their presence ensures an additional layer of safety, as they can provide immediate feedback about the system's status and help monitor any changes in the environment that may occur during maintenance. An operator can also assist in implementing emergency procedures if something goes wrong, making them an essential resource when working on potentially disruptive controls. While notifying personnel, conducting a risk assessment, and powering down machinery are important safety practices in general, having an operator present directly addresses the need for immediate expertise and oversight in a live operational environment, enhancing safety and ensuring a smooth workflow.
