Why is it essential for all personnel to know the signals used?

Understanding the signals used in crane operations is vital for ensuring clear and effective communication among all personnel involved in the lifting process. When everyone is knowledgeable about the signals, it promotes a shared understanding of instructions and intentions, which is critical for maintaining safety on the job site. Miscommunication can lead to dangerous situations, including accidents and injuries. Therefore, having a comprehensive grasp of the communication system helps all team members coordinate their actions, respond quickly to commands, and ultimately support a safer work environment.
