When is it necessary to use a tag line during lifting operations?

• A. When lifting light materials
• B. To control the load and prevent swinging
• C. Only when instructed by a supervisor
• D. When working in enclosed spaces only

Answer: (B)

Using a tag line during lifting operations is necessary primarily to control the load and prevent swinging. Tag lines are ropes or lines attached to a load to help guide it and keep it stable during lifting. This added control is crucial for preventing hazards that arise when a load swings or rotates unexpectedly, which can pose risks to operators and nearby personnel.

Utilizing a tag line allows operators to direct the load in a more controlled manner, especially in situations where the lifting equipment is not able to maintain a stable trajectory of the load. This can significantly enhance safety and precision during the lifting process, especially in dynamic environments where external factors may affect the load.

In contrast, the other answers do not capture the essential function of a tag line in lifting operations. Light materials might not require a tag line due to their manageable weight, and relying solely on a supervisor's instruction does not encompass the fundamental safety measures. Moreover, suggesting that tag lines are only used in enclosed spaces overlooks their importance in various operating conditions.
