Standard Colors for Your Underground Utilities
Underground utilities can easily be identified today. 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. It is to prevent disaster. The worst thing that can happen if lines are not identified is that fatal injuries can happen. The location of the areas where the lines were struck can experience service interruption. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. When the number is called, you can let the utility companies come out and mark their respective lines.
Marking lines may lessen the risks but there are time when accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.
GPR or Ground Penetrating Radar is used by companies to locate their utility lines. This has made it easier to locate utility lies underground and other important things. Companies can locate their utility lines if any property owner calls 811.
Today, utility lines are marked with different colors for easy identification. Below are some of the colors used for different utility lines.
Proposed excavation sites use white lines. Area that will be excavated in the future are marked.
If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. This color is appropriate for electrical works since it is associated with fire and danger.
If you see yellow lines, then they are lines for gas, oil, steam, petroleum, and gaseous materials. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Lines for potable water use blue lines. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. A project can be derailed for a long time when these utility lines are hit.
