The main purpose of having a signal person during crane operations is to communicate the operator’s instructions and ensure safety during lifts. The signal person plays a crucial role in the coordination between the crane operator and the surrounding work environment. This is vital, especially in complex jobs where visibility may be limited for the operator.

Having a dedicated signal person helps to ensure that all movements of the crane are executed safely and according to plan. They are trained to provide clear and precise signals, which allows for effective communication regarding load movements, positioning, and potential hazards. This level of coordination minimizes the risk of accidents and enhances the overall safety of the lifting operation.

In the context of crane operations, the focus is on clear communication and safety. While supervision, inspection, and management on site are important, they are not the primary role of the signal person. Their responsibility centers specifically around facilitating safe and effective lifting operations through communication.
