The Importance of Colors of Underground Utility Lines
It is now easier to know what an underground utility line is for. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. Although not completely eliminated, risks today have been reduced. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. The OSHA requires that utilities underground first be located before digging through a piece of land. Otherwise it can be something disastrous. 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. These incidents affect 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. 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. Below are some of the colors used for different utility lines.
If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Pink lines 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.
If you see yellow lines, then they are lines 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. 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.
