What is a common signal for indicating a safe work zone on a construction site?

Using barricades or cones is a widely recognized method for creating a safe work zone on construction sites. These physical barriers serve multiple safety functions, including directing pedestrian and vehicle traffic away from hazardous areas, clearly marking where work is taking place, and preventing unauthorized access to potentially dangerous locations. By establishing a clear boundary, barriers and cones communicate visual cues to workers and the public, enhancing situational awareness and minimizing the risk of accidents. Their bright colors and reflective materials make them highly visible, further ensuring that everyone can readily identify the extent of the work zone. This type of signaling is a fundamental part of safety protocols on construction sites, reinforcing the importance of maintaining safety awareness in active work environments.
