What color is used to identify natural gas piping?

• A. Blue
• B. Red
• C. Green
• D. Yellow

Answer: (D)

Color coding makes gas lines instantly recognizable, which is crucial for safety when installing, inspecting, or repairing piping. Natural gas piping is identified with yellow, a bright, high-visibility color that stands out from typical building materials and other systems. This consistent use of yellow across pipelines helps workers and first responders quickly distinguish gas lines from water, electrical, or other utilities, reducing the risk of damage or incorrect connections. While other colors are used for different services, they don’t indicate natural gas, so yellow is the correct choice for identifying natural gas piping.
