Why is it important for a signal person to stop all movement if unsure?

The importance of stopping all movement if a signal person is unsure lies in the fundamental priority of ensuring safety and clarity on a worksite. When there is uncertainty, moving equipment or personnel can lead to accidents, injuries, or damage to property. By halting operations, the signal person allows for a moment of assessment where they can clarify instructions, communicate effectively with the operators, and ensure that everyone is on the same page regarding the next steps.

This practice is critical not only for the safety of the personnel involved but also for maintaining effective communication and operational efficiency. Unclear signals or misunderstood instructions can result in dangerous situations, so taking the time to confirm details promotes a culture of safety and prevents potentially catastrophic outcomes.
