Undergoung Utilities and their Standard Colors
Underground utilities can easily be identified today. 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. The OSHA requires that utilities underground first be located before digging through a piece of land. You dont want something disastrous to occur. 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. 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.
Sometimes, even if the lines are marked accidents still happen. 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. This is then something that affects public health and safety.
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. 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.
Pink lines are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. If you see the color green, then it indicates sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
