What must an observer do during crane operations?

During crane operations, the observer must not perform any other tasks. This focus is crucial for safety and effective communication during lifting operations. The observer’s primary responsibility is to monitor the entire operation, maintain situational awareness, and ensure that the crane operator is informed about any potential hazards or issues that may arise. By concentrating solely on observing the lift, the observer can provide clear and timely signals to the operator, ensuring that everyone involved is aware of the load's status and any changes in the environment.

When the observer is not distracted by other tasks, they can effectively monitor the surroundings for pedestrians, nearby equipment, and any obstacles. This vigilance helps prevent accidents and ensures that the crane operation proceeds safely and efficiently. Engaging in multiple tasks or constant signaling would divide the observer's attention, potentially leading to oversight and jeopardizing the operation's safety.
