Which hand signal involves extending one arm and rotating the wrist?

The hand signal that involves extending one arm and rotating the wrist is associated with the action of "swinging" a load. This motion effectively communicates to operators that the load should be laterally moved, typically from side to side. The action of extending one arm and rotating the wrist illustrates the direction and intention to move the load horizontally, which is crucial for coordinating safe rigging and hoisting operations.

The clarity of this signal is vital for ensuring that all personnel involved understand the intended movement, thereby reducing the risk of accidents or miscommunication during the operation. Proper signaling practices reinforce the importance of visual cues in ensuring safety and efficiency on the job site.
