Why are flags or beacons important at work sites?

Flags and beacons play a crucial role at work sites primarily by enhancing visibility and ensuring safety. Their presence helps to alert workers and the public to potential hazards, such as construction areas, maintenance activities, or overhead work. By increasing awareness of the work site, these visual signals can significantly reduce the risk of accidents and injuries.

In environments where visibility may be compromised due to weather conditions, time of day, or the nature of the work being performed, flags and beacons serve as essential safety tools. They help direct attention to specific areas where caution is needed, guiding both workers and pedestrians to navigate safely around potential dangers. Their primary function is to promote a safer work environment, making them a fundamental part of safety protocols in various industries.

While other options may mention aspects of aesthetics or communication, they do not align with the primary importance of visibility and safety that flags and beacons provide.
