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. Today, the risks have been lessened although not completely eliminated. 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. Otherwise it can be something disastrous. The worst thing that can happen if lines are not identified is that fatal injuries can happen. 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.
But, despite the marks, there will sill be accidents. The reality is that there is an incident almost every 6 minutes where utility line are struck. 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.
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.
There are certain colors that mark different utility lines for easy identification. The colors below indicate the kind of utility uses it.
If you see white lines, then these are proposed excavation sites. 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.
If you see red lines, then you can be sure that these are electric power lines, cable, conduit, and lighting cables. 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. 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. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. Green lines are used for sewer and drain lines. You can derail any project for a long time if you hit these lines.
