What standard hand signal indicates 'Use whip line'?

The hand signal that indicates 'Use whip line' is particularly defined to ensure clear communication between riggers and operators during lifting operations. In rigging, the whip line is a secondary line used to control a load more precisely or to maneuver it into a specific position.

Using a dedicated hand signal for 'Use whip line' helps prevent confusion over what type of line or hoist should be utilized during the operation. This is crucial in maintaining safety and efficiency, especially when multiple lines and equipment might be in use simultaneously. The specificity of the signal directly contributes to safer handling practices by ensuring that everyone involved understands exactly what is required, reducing the risk of accidents or equipment damage.

The other choices might represent common lifting commands or actions, but they do not convey the explicit instruction to utilize a whip line, which is essential for precise load manipulation.
