What should signal persons do if they become tired during operations?

Signal persons play a critical role in ensuring safety and effective communication on construction sites or during heavy equipment operations. If a signal person starts to feel tired, it's essential for them to prioritize safety, not only for themselves but also for everyone involved in the operation. Notifying a supervisor and being replaced is the appropriate action to take because fatigue can impair judgment, reaction times, and overall performance, which could lead to accidents or safety incidents.

By informing a supervisor about their fatigue, a signal person ensures that the operation can continue safely with someone who is alert and capable of performing their duties effectively. This approach promotes a culture of safety and responsibility in the workplace. It also allows for proper personnel management, as supervisors are trained to handle such situations and can take steps to quickly find a qualified replacement.
