Who should participate in the pre-lift meeting to ensure all personnel understand the plan?

• A. The public visitors.
• B. Operators, spotters, riggers, and the supervisor.
• C. Only the crane operator.
• D. The client and vendors only.

Answer: (B)

This question tests the importance of bringing together everyone who will directly influence and execute the lift so the plan is understood by all involved. A pre-lift meeting should include operators, spotters, riggers, and the supervisor because each plays a distinct, safety-critical role: the operator controls crane movements, the spotters guide loads and maintain safe distances, the riggers prepare and secure the load, and the supervisor ensures the plan is followed and safety rules are met. In the meeting, they review the lifting sequence, load weight and balance, crane setup, ground conditions, signals and communication methods, and what to do if something goes wrong. This shared understanding helps prevent miscommunication and discipline-specific blind spots, keeping everyone aligned on responsibilities and contingencies.

Public visitors are not part of the lift crew and shouldn’t participate in this safety-critical planning. Relying on only the crane operator ignores the need for coordination and clear roles among the crew. Clients or vendors may have interests in the project, but they aren’t responsible for directing the on-site lift operations, so they don’t ensure the team-wide understanding needed for a safe lift.
