How should personnel be alerted before a lift operation?

Before any lift operation, it is crucial to ensure that all personnel are clear of the lift area and properly informed about the operation details. This approach emphasizes safety and communication, as it helps to minimize risks associated with lifting operations. Making sure everyone understands what is about to happen allows them to take the necessary precautions and positions themselves safely.

While other options might involve methods of communication, they do not ensure comprehensive awareness and the safety of all personnel involved. Hand signals, shouting commands, and visual signals may be effective in certain contexts, but they do not guarantee that everyone in the vicinity is fully aware of the lift operation or clear from potential hazards. The approach of confirming that all personnel are clear and informed is a foundational safety practice that enhances the effectiveness of the operation and protects everyone on site.
