What is a “tag line” used for in hoisting operations?

A “tag line” is an essential safety tool used in hoisting operations that helps to control the load being lifted. It is typically a rope that is secured to the load and held by personnel on the ground. The primary purpose of the tag line is to provide stability and guidance during the lifting process, allowing operators to maneuver the load safely and prevent it from swinging or rotating unexpectedly.

Using a tag line enhances safety by enabling ground personnel to assist in controlling the direction and position of the load as it is lifted and transported. This is particularly important in environments where obstacles or other hazards may be present. The use of a tag line helps reduce the risk of accidents and ensures that the load is handled more effectively and precisely.

In contrast, other options do not accurately describe the function of a tag line. Measurement tools and signal devices serve different roles in hoisting operations, and safety features for emergency stops are part of a broader safety system that includes brakes and control mechanisms, rather than being related to the handling of the load during lifting.
