What is the color code for identifying gas lines on Dig Safe markings?

The color code used to identify gas lines on Dig Safe markings is yellow. This standardization helps workers and contractors quickly and accurately locate underground utilities before beginning any excavation work. Yellow is specifically designated for gas, petroleum, and other hazardous materials, providing a clear visual cue to ensure safety and mitigate the risk of accidents that could occur from accidentally drilling into a gas line. The other colors in the Dig Safe system are associated with different types of utilities, such as red for electric, blue for water, and green for sewer or drain lines, which emphasizes the importance of knowing these color codes in the context of excavation safety.
