Under what condition can a clearance be released?

Releasing a clearance is a critical step in ensuring the safety and proper operation of a worksite, particularly in contexts involving cranes and diggers. The correct answer emphasizes the importance of ensuring that all employees are clear from any potential hazards associated with the task before removing tags or other safety indicators.

When all employees are clear, it indicates that no one is in the area that could be affected by the equipment's operation. In addition, ensuring that grounds have been removed is vital because it minimizes the risk of electrical hazards. Removing tags without confirming these conditions could lead to dangerous situations, as it might indicate that operations can resume while individuals are still in a hazardous zone.

This process not only protects the personnel on-site but also aligns with safety regulations and protocols, which mandate a thorough review of conditions before it is considered safe to resume work.
