What color is generally used for gas piping to indicate its use?

In the context of gas piping, yellow is the color commonly used to indicate its use. This color coding standard serves an important safety function, helping to distinguish gas lines from other types of piping and ensuring that workers and the public can recognize and identify gas piping systems quickly. Yellow is universally understood in the industry as being associated with natural gas lines, which is critical in preventing accidents and ensuring proper handling during installation, maintenance, and repairs.

Using specific colors for different types of gas ensures that precautions can be taken appropriately. For example, when excavation work is being conducted, the visibility of the yellow color helps to alert workers to the presence of gas lines, encouraging them to exercise caution. Other colors in a piping color code system are designated for different utilities or applications, such as red often indicating fire protection and blue for potable water, which illustrates the importance of using the correct color to minimize confusion and recognize the type of service being provided.
