Which of the following describes the proper procedure before moving a line set?

• A. The operator moving the line set.
• B. Any nearby audience member.
• C. The stage manager.
• D. The person who last touched the line set.

Answer: (A)

The essential rule is that the operator responsible for a line set must be the one to move it. This ensures the person handling the movement is trained to manage the rigging, counterweights or motors, and the path the line set will take. The operator is the point of contact for coordinating with the crew, giving the proper warnings, and confirming that the fly space is clear—no people, gear, or loose items in the way—and that all hardware is secured and within safe limits before starting. This focused responsibility prevents miscommunication and reduces the risk of injury or equipment damage.

Relying on an audience member to move it is unsafe because they typically lack training and awareness of hazards. The stage manager can coordinate safety and calls, but the actual movement must be performed by the trained operator who understands the rigging system. The person who last touched the line set may not reflect the current status or conditions, which can change after contact and lead to unsafe movement.
