What should a signaler's hand signal checklist include?

• A. Clear stop signals, slow movements, use of whistle, eye contact with operator, and correct visibility.
• B. Quick proceed signals with no need for eye contact.
• C. Signals only necessary when visibility is good.
• D. Signals should be given by radio only.

Answer: (A)

Clear, reliable communication between the signaller and the crane operator depends on signals that are easy to see, easy to understand, and can be confirmed. A solid hand signal checklist should include clear stop signals so the operator knows exactly when to halt, slow and controlled movements so the load can be guided safely without sudden jerks, the use of a whistle to reinforce signals in noisy environments, eye contact with the operator to confirm that the signal has been seen and understood, and ensuring the signals are clearly visible to the operator at all times. This combination reduces the chance of miscommunication and helps the operator respond promptly and safely. Signals that focus on quick, casual movement without eye contact, or that rely only on radio, ignore the need for clear visual cues and direct acknowledgment, which are essential for safe signaling in crane operations.
