Natural gas pipes are typically yellow.
This color coding is a standard practice to quickly identify and differentiate underground utilities. The use of yellow specifically designates lines carrying natural gas, oil, steam, petroleum, or other gaseous or flammable materials. This helps prevent accidental damage during excavation and construction activities.
Here's a breakdown of common utility color codes:
| Color | Utility |
|---|---|
| Red | Electric power lines, cables, conduit, and lighting cables |
| Yellow | Natural gas, oil, steam, petroleum, or other gaseous or flammable materials |
| Green | Sanitary sewers and drain lines |
| Orange | Telecommunication, alarm or signal lines, cables, or conduits |
| Blue | Potable water |
The consistent use of these colors contributes to safety and helps protect underground infrastructure.
