Which color is used for newer gas pipe identification?

• A. Orange/Beige/Salmon
• B. Blue
• C. Green
• D. Yellow

Answer: (D)

Color coding helps crews quickly identify what kind of utility is buried and take the right safety steps before digging. For newer gas pipe installations, yellow is the standard color used to mark gas lines. This convention is part of widely adopted utility color codes, where yellow signals gas. Blue typically marks water, and green marks sewer, so choosing yellow directly aligns with the usual labeling system for gas piping. Recognizing yellow as the gas indicator helps ensure proper precautions, like calling for locator services and avoiding excavation near marked lines.
