Undergoung Utilities and their Standard Colors
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. 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. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. It can also interrupt services in your area where the line is located. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Calling the 811 number will enable utility companies to come out and mark their respective utility lines.
But, despite the marks, there will sill be accidents. It is said that every 6 minutes, there is a utility line that is struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. When locating utility lines underground, this machine makes it easy to do so. Companies can locate their utility lines if any property owner calls 811.
There are certain colors that mark different utility lines for easy identification. Here are the colors used for different utilities.
If you see white lines, then these are proposed excavation sites. 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. 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. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.
Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
