The primary purpose of having a signal person during lifting operations is to direct the operator and ensure that the lift is conducted safely and accurately. This individual plays a crucial role in the communication between the ground crew and the operator, especially in situations where the operator's line of sight may be obstructed or when complex maneuvers are involved. The signal person understands the operational parameters and is trained to provide clear, standardized signals that convey instructions effectively.

Utilizing a signal person helps to minimize the risk of accidents by ensuring that the operator has real-time information about the load, the environment, and any potential hazards. This enhances operational efficiency and safety by allowing the operator to focus on the equipment while relying on the signal person's guidance to navigate the lifting process.

In contrast, the other roles mentioned do not align with the core responsibilities of a signal person. For instance, representing multiple operators in the field may lead to confusion and miscommunication. Providing casual feedback does not provide the structured and necessary communication needed for safety during lifting operations. Handling all lifting loads independently contradicts the collaborative nature of lifting operations, which require coordinated efforts to maintain safety standards.
