Standard Colors for Your Underground Utilities
If you find underground utilities, you can easily determine what type of utility it is for. However, a long time ago, it was difficult to identify these utility lines and so when people try to dig there were many risks involved. Today, the risks have been lessened although not completely eliminated. If there is a need to dig the ground, it is very important that the utility lines first be identified. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. If you hit any of the underground utility lines while digging then you can be fatally injured. Services in the area where the lines are located can experience interruption. People can call 811 to prevent these incidents, before they proceed with digging their property. Utility companies can then mark out their respective lines when you call them out.
But, despite the marks, there will sill be accidents. The reality is that there is an incident almost every 6 minutes where utility line are struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. This is then something that affects public health and safety.
Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. This has made it easier to locate utility lies underground and other important things. Calling 811 is enough for the property owner to let companies located their lines.
There are certain colors that mark different utility lines for easy identification. The colors below indicate the kind of utility uses it.
White lines are for proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Pink lines are temporary survey markings. Legal property boundaries are marked off by these pink lines.
If you see red lines, then you can be sure that these are electric power lines, cable, conduit, and lighting cables. This color is appropriate for electrical works since it is associated with fire and danger.
Yellow lines are used for gas, oil, steam, petroleum, and gaseous materials. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.
Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Green lines are used for sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
