Standard Colors for Your Underground Utilities
If you find underground utilities, you can easily determine what type of utility it is for. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. You dont want something disastrous to occur. The worst thing that can happen if lines are not identified is that fatal injuries can happen. 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.
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. 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. When locating utility lines underground, this machine makes it easy to do so. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
Today, utility lines are marked with different colors for easy identification. Here are the colors used for different utilities.
Proposed excavation sites use white lines. You can mark areas with white lines that will soon be excavated.
If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
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. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.
Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. Green lines are used for sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
