What must the operator, signalman, and crew attend prior to hoisting a personnel platform?

The correct answer focuses on the importance of holding a pre-lift meeting before hoisting a personnel platform. This meeting serves as a critical step in ensuring that everyone involved is on the same page regarding the specific details of the lift. It allows the operator, signalman, and crew to discuss the lift plan, identify potential hazards, and clarify roles and responsibilities. By communicating openly during this meeting, it reduces the risk of miscommunication or errors during the lift, thereby enhancing safety for all personnel involved.

While safety briefings, weather assessments, and risk evaluations are essential components of a comprehensive safety program, they do not specifically address the detailed planning and collaborative communication that a pre-lift meeting provides, which are crucial for the success of the operation on-site.
