What precautions must be taken before returning a clearance?

• A. Notify employees under his or her direction that the clearance is to be released
• B. That all employees in the crew are clear of the lines and equipment
• C. That all protective grounds installed by the crew have been removed
• D. All the above

Answer: (D)

The essential idea is to ensure everyone and everything is safe and accounted for before an electrical circuit is energized again. Notifying all personnel under your direction that the clearance is about to be released creates a heads-up so workers know to finish any remaining tasks and stay clear as the area resets. Verifying that all employees in the crew are clear of lines and equipment guarantees there’s no one in the danger zone who could be injured when power is restored. Removing all protective grounds installed by the crew is crucial because those grounds were put in place to protect during de-energized work; leaving them in place could mislead people about the status of the system or create a hazard if re-energization occurs. Taken together, these steps ensure clear communication, a physically safe clearance boundary, and proper removal of temporary safety measures before re-energizing.
