Who must be present for the pre-lift discussion when using voice signals?

The pre-lift discussion is crucial for ensuring safety and coordination during a lift operation, particularly when voice signals are in use. Having the Lift Director, Signalman, and Operator present allows for comprehensive communication about the specific lift to be performed, including any potential hazards, the lift plan, and roles and responsibilities.

The Lift Director is responsible for overseeing the lift operation and ensuring that all safety protocols are followed. The Signalman communicates directly with the operator and is responsible for guiding the lift, ensuring that the operator has a clear understanding of the signals and the lift plan. The Operator is the person who will execute the lift, following the directions provided by the Signalman. The presence of all three parties creates a collaborative environment where questions can be addressed, clarifications can be made, and everyone involved is on the same page, which is essential for a safe and efficient lift operation.

This option effectively captures the need for multiple roles to be engaged in the pre-lift discussion, highlighting the importance of teamwork in ensuring safety and effectiveness during crane operations.
