What must a signal person, operator, and lift director do when using non-standard signals?

When utilizing non-standard signals in a lifting operation, it is crucial for all parties involved, including the signal person, operator, and lift director, to agree on the method of signals to be used. This agreement ensures that everyone is on the same page regarding the meaning of the signals, which is vital for maintaining safety and efficiency during the lift. Since non-standard signals may not have universally accepted meanings, clear communication and understanding among team members help prevent misunderstandings that could lead to accidents or improper handling of the load. Collaborative understanding also builds trust and reinforces the importance of teamwork in crane operations.

Accordingly, while some options might suggest alternative practices, they do not support the necessary collaborative communication that is essential for safely executing lifts using non-standard signals.
