What color paint do excavators typically use to mark work area boundaries?

1. Red

2. Yellow

3. Blue

4. White

The correct answer is: White

The correct answer is white, which is commonly used for marking work area boundaries in excavation and construction settings. White paint typically denotes general site boundaries and areas where excavation or digging is planned. This high-visibility color serves to alert workers and the public to the presence of ongoing work, helping to ensure safety and prevent accidental intrusions into the marked area. Each color used in marking practices has a specific meaning. For example, red is often reserved for marking electric lines, yellow for underground gas lines or pipelines, and blue for potable water. Understanding the significance of these colors is crucial for maintaining safety protocols and complying with local regulations during excavation projects. This knowledge helps workers identify hazards effectively and reduces the risk of accidents on the job site.
