What is the primary purpose of using a tag line during lifting operations?

The primary purpose of using a tag line during lifting operations is to control the load's movement. A tag line is a rope or line secured to a load that allows personnel to guide and stabilize the load as it is lifted, swung, or positioned. By controlling the load's movement with a tag line, riggers can help ensure that it remains in a safe and predictable path, reducing the risk of swinging, rotating, or otherwise moving unexpectedly, which can lead to accidents or injuries.

Using a tag line contributes to the safety and efficiency of lifting operations by enabling clear communication and control over the load. While signaling from a distance or increasing load capacity may seem beneficial, these functions are not the primary role of a tag line. Similarly, adding weight to the load would counteract the original intent of safe lifting practices.
