Which statement best describes the visibility requirement for the spotter during crane operations?

• A. Always maintain clear sight of the operator
• B. Never required
• C. Only during critical lifts
• D. Only when the operator requests

Answer: (A)

Maintaining a continuous line of sight between the spotter and the operator is essential. The spotter uses signals to guide crane movements and needs to clearly observe the operator’s actions to ensure there’s no miscommunication and to respond immediately if something looks unsafe. If the spotter can’t see the operator, signals can be missed or misinterpreted, increasing the risk of an accident. Therefore, the best practice is to always keep the operator in clear view.

Other options would create gaps in communication and delay hazard recognition: not required at all would ignore safety; only during critical lifts would leave other lifts unmonitored; only when requested shifts responsibility away from continuous safety oversight. If visibility is ever compromised, the lift should be stopped until it’s restored.
