Older gas pipe color coding includes which color?

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

Answer: (C)

Color coding helps workers quickly identify what a pipe carries, which is crucial for safety during maintenance and excavation. In older gas systems, the pipes were painted in orange, beige, or salmon tones. This warm, lighter hue stood out and signaled gas service, helping distinguish gas lines from water, sewer, or electrical conduits. Today, many places use yellow to mark gas lines, but the older practice used those orange/beige/salmon colors. The other options align with other utilities or modern practices (blue for water, green for sewer), not the older gas-pipe scheme.
