What must be ensured before a supervisor removes someone else's lock?

Before a supervisor removes someone else's lock, it is essential to ensure that the individual is unavailable or that their duties are complete. This safety measure is critical to prevent accidents or injury due to unexpected access to equipment.

If the person is unavailable, it generally means they are unable to return to the area safely, making it appropriate for the supervisor to take action. Similarly, ensuring that the individual's duties are complete confirms that there is no risk of interrupting their work processes or jeopardizing their safety. By meeting these conditions, the supervisor acts responsibly and adheres to safety protocols, ensuring a safe working environment for all personnel.
