Who has the authority to release a clearance once a crew has it?

The designated person in charge holds the authority to release a clearance once a crew has it. This individual is responsible for ensuring that all safety protocols and procedures are followed throughout operations. Their training and position empower them to assess the situation adequately and verify that all conditions for releasing the clearance have been met. This includes confirming that equipment is safe to operate, that the work area is clear and secure, and that all necessary checks have been completed.

The authority of the designated person in charge reflects the importance of maintaining a structured safety management system where responsibilities are clearly defined. Such a system helps to minimize risks associated with crane and digger operations by ensuring that only someone with appropriate knowledge and training makes critical safety decisions.
