In a repair scenario for a radio controlled crane, which person is responsible for the control box?

• A. Designated repair crew member
• B. Any repair crew member
• C. A disgusted person not on the crane
• D. The shift supervisor

Answer: (A)

During a repair, the radio control box must be under the control of a single, authorized person. The designated repair crew member is the one trained and assigned to handle the control box, ensuring only a qualified individual can operate or stop the crane while work is being done. This prevents unintended crane movement and provides clear accountability for the controls during maintenance. Other crew members should not have general control or operate from outside the crane, and while the shift supervisor oversees safety, the specific responsibility for the control box during repairs lies with the designated repair crew member.
