What is the purpose of a "tag line" in rigging operations?

The purpose of a "tag line" in rigging operations is to control the movement of a load while it is being lifted. A tag line is a length of rope or cord that is attached to a load during lifting operations, allowing operators to manage and direct the load's position and movement from a safe distance. This control is essential for maintaining stability and preventing the load from swinging uncontrollably due to wind or other environmental factors, as well as minimizing the risk of accidents and ensuring safety for personnel involved in the operation. It enhances precision when placing the load in its intended location, which is crucial in complex rigging scenarios.

Other options focus on aspects unrelated to the primary role of a tag line. For instance, securing the load to the ground and attaching the load to the crane involve completely different tools and methods, while measuring load size is not associated with the function of a tag line in rigging operations.
