What is the purpose of using a tag line?

Using a tag line is primarily about controlling the load during lifting and lowering operations. The tag line is a secondary line attached to the load, which is used by workers to guide and stabilize it as it moves. This helps prevent the load from swinging or spinning uncontrollably, which could pose safety hazards or lead to damage to the load or surrounding structures. By maneuvering the tag line, workers can direct the load more accurately and maintain better control, ensuring a safer and more effective lifting process.

The other choices highlight different aspects of rigging and lifting but do not align with the primary function of a tag line. For instance, assessing weight is typically done prior to the lift and does not involve tag lines. Protecting the load from damage would usually involve padding or cushioning methods, rather than the use of a tag line. Similarly, reeling in slack is a function associated with the lifting mechanism itself, rather than the use of a tag line.
