What is the recommended action for the signalperson if they lose sight of the operator?

When a signalperson loses sight of the operator, maintaining effective communication is critical to ensure safety and coordination. Using radio communication allows the signalperson to convey necessary signals and instructions without direct visual contact. This approach helps prevent accidents and misunderstandings, keeping all personnel informed about the status of operations. It enables the signalperson to continue overseeing the lifting operation effectively until visual contact can be reestablished.

Waiting for visibility to improve could delay operations unnecessarily and may not be practical, especially in dynamic environments. Continuing to use hand signals without ensuring the operator can see them could lead to confusion or accidents. Stopping all operations immediately may not be necessary if there is a means to communicate effectively with the operator, especially if the situation demands continuity in operations.
