What color of paint is typically used to mark an excavation area?

1. Red

2. Brown

3. White

4. Green

The correct answer is: White

The color of paint typically used to mark an excavation area is white. In utility markings, white is specifically designated for proposed excavations or dig sites. It serves as a clear indicator to various stakeholders—such as contractors, utility companies, and workers—of areas where soil disturbance is planned. There are specific color codes established by the American Public Works Association (APWA) that guide the use of colors for marking different types of underground services and hazards. While red is used to mark electric power lines, brown for temporary survey markings, and green for sewer and drain lines, white's role is crucial in delineating the regions where excavation might occur, thus helping to prevent accidental damage to existing underground utilities and minimizing safety risks during excavation projects.
