CWEA Maintenance Technologist Practice Test

What action is necessary before restarting rotating equipment that has recently undergone repair?

1. All removed guards must be installed

2. The equipment must be tested in idle mode

3. A safety inspection must be completed

4. The operator must be in position

The correct answer is: The equipment must be tested in idle mode

The necessary action before restarting rotating equipment that has recently undergone repair is to test the equipment in idle mode. This step is crucial as it allows for the identification of any issues or abnormalities in the equipment's operation post-repair without putting any personnel or the machinery at risk. Testing in idle mode helps ensure that all components are functioning properly and that the equipment is safe to operate under load. While ensuring that guards are installed, completing a safety inspection, and positioning the operator are all important safety measures, the priority in the immediate post-repair phase is to confirm that the mechanics of the equipment are sound and that there are no unexpected behaviors before moving to operational use. Hence, testing in idle mode serves as a vital precautionary measure to validate that repairs were successful and that the equipment can safely handle its operational duties.
