Which of the following best describes an important safety practice for signal persons?

Maintaining a clear line of sight at all times is crucial for signal persons as it ensures effective communication with the crane operator and an ability to observe the surrounding area. This visibility helps in preventing accidents and improving situational awareness, as the signal person can anticipate potential hazards and respond appropriately. Clear communication is vital because it allows the signal person to convey instructions and warnings promptly, thereby supporting a safer working environment.

Good visibility also enhances the signal person's ability to monitor the load being moved and the area below it, ensuring that it is clear of personnel or obstacles. This practice not only prioritizes the safety of the signal person but also the safety of other workers in the vicinity, making it a fundamental aspect of safe crane operation.
