NCCCO Mobile Crane Practice Exam 2025 - Free Crane Operator Certification Practice Questions and Study Guide

A signal person must be a designated individual who has received testing and demonstrated competency in signaling for crane operations. This requirement ensures that the person has the necessary skills and understanding of the signals, communication methods, and safety protocols essential for clear and effective coordination during lifting operations.

Having a designated, tested signal person is important to minimize the risk of accidents and miscommunication on the job site. This person is tasked with providing clear guidance to the crane operator and other personnel involved in the lift, ensuring that all actions are conducted safely and efficiently. The competencies the signal person must possess include knowledge of hand signals, the ability to read and interpret the worksite conditions, and an understanding of the specific equipment being used.

This role cannot simply be filled by a volunteer with experience, any operator, or someone with no prior training, as those alternatives do not ensure a standardized level of competency and training necessary for safety in the workplace.
