The correct answer is that a dedicated spotter must also have qualifications as a signal person. This requirement is rooted in the need for effective communication and safety in construction operations involving cranes and hoisting activities.

Being qualified as a signal person means that the individual has the necessary training and understanding of hand signals, communication methods, and the operation of the crane itself. This dual qualification allows the spotter to assist effectively in coordinating lifting operations and maintaining safety protocols. Therefore, having knowledge and skills as a signal person enhances the overall safety and efficiency of the operation, thus meeting OSHA requirements.
