What should a signalperson do if they lose sight of the crane during operation?

In a scenario where a signalperson loses sight of the crane during operation, the most appropriate action is to communicate immediately to stop the operation. This is crucial for several reasons.

First, losing sight of the crane poses a significant safety risk as the operator may not be aware of surrounding hazards or changes in the work environment that could affect the safety of the operation. Stopping the operation ensures that no potential accidents occur while the signalperson regains visual contact and assesses the situation.

Second, maintaining clear communication and control over crane operations is essential in ensuring the safety of all workers in the vicinity. By halting the operation, it provides a moment for the signalperson to either regain their line of sight or communicate with the crane operator and other personnel about the situation.

Lastly, this action aligns with standard safety protocols, where the responsibility to halt operations in unsafe conditions falls upon the signalperson. It emphasizes the concept that safety always takes precedence over continuing operations without complete situational awareness.
