The Importance of Colors of Underground Utility Lines
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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. It is thus important that we know how to identify these underground utilities if there is a need to dig the ground so that you can prevent harm. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. It is to prevent disaster. Fatal injuries can happen if underground utility lines are struck. It can also interrupt services in your area where the line is located. 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. Utility lines are struck every 6 minutes, some place. When utility lines are stuck it causes disturbances in 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. With this machine, companies can easily locate utility lines. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
There are certain colors that mark different utility lines 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.
Temporary survey markings use pink lines. These are used by surveyors 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.
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. Lines for potable water use blue lines. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. Sewer and drain lines use the color green. You can derail any project for a long time if you hit these lines.
