What color is used to indicate natural gas lines?

Natural gas lines are designated by the color yellow. This color coding is part of a national standard aimed at ensuring safety and preventing accidents during excavation or construction activities. The yellow color serves as a clear visual indicator, helping to alert workers and the public that natural gas lines are present in the vicinity. This is particularly important as it aids in the prevention of accidental strikes or damage to the gas lines, which could lead to dangerous leaks or explosions. The use of specific colors in utility marking not only enhances safety but also promotes awareness of the various utility lines underground, each associated with different colors according to their purpose.
