The Importance of Colors of Underground Utility Lines
Underground utilities can easily be identified today. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. If there is a need to dig the ground, it is very important that the utility lines first be identified. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. 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.
But, despite the marks, there will sill be accidents. Utility lines are struck every 6 minutes, some place. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. 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. 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. 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. Surveyors use pink lines to mark off legal property boundaries.
Electric power lines, cable, conduit, and lighting cable use red lines. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
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.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. Blue lines are used for potable water. If you see purple lines, that this is 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.
