What is one essential skill that a qualified signal person must possess?

A qualified signal person must have a thorough knowledge of hand and voice signals because clear communication is vital in ensuring safety on a construction site. The signal person's primary role involves directing the movement of equipment and loads, and this is achieved through standardized signaling methods. Understanding and executing these signals correctly enables the operator and other workers to interpret instructions accurately and respond accordingly, thereby reducing the risk of accidents and enhancing overall site safety.

While abilities like reading blueprints, machine maintenance, and understanding load dynamics are beneficial traits for construction workers, the ability to communicate effectively through signals is crucial for a signal person’s responsibilities. This specialized knowledge directly impacts the efficiency and safety of operations involving cranes and other lifting equipment, making it the most essential skill in this context.
