When a line is cleared for work, who receives the clearance from the system operator?

The correct answer is that the designated person receives the clearance from the system operator when a line is cleared for work. This individual is specifically appointed or trained to be responsible for managing safety and communication during operations. Their role is crucial in ensuring that all safety protocols are followed and that everyone on site is informed of the clearance, thereby minimizing risks associated with the operation of machinery like mobile cranes and diggers.

The designated person's training ensures they understand the procedures necessary for obtaining clearance, interpreting safety signals, and communicating effectively with both the system operator and the crew. By having a designated individual handle this responsibility, clarity and accountability are maintained, which is essential for safe operations in potentially hazardous environments.
