If a person signaling to back or shove disappears, what is the required action?

When a person signaling to back or shove disappears, the required action is to stop backing or shoving immediately. This ensures the safety of personnel and prevents potential accidents. The absence of the signal indicates that the operator can no longer verify the safety of the movement. Stopping ensures that the equipment does not encroach on areas where it could come into contact with personnel, other equipment, or obstructions, mitigating the risk of injury or damage.

Maintaining a thorough understanding of communication protocols is essential in these operational scenarios. If the signaling individual becomes obscured or cannot be seen, ceasing movement is the safest course of action until clarity is restored regarding the situation.
