The Importance of Colors of Underground Utility Lines
It is now easier to know what an underground utility line 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. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. It is to prevent disaster. Fatal injuries can happen if underground utility lines are struck. Services in the area where the lines are located can experience interruption. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. 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. These incidents affect public health and safety.
GPR or Ground Penetrating Radar is used by companies to locate their 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.
Today, utility lines are marked with different colors for easy identification. The colors below indicate the kind of utility uses it.
White lines are for proposed excavation sites. You can mark areas with white lines that will soon be excavated.
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 perfect for electric works because it is associated with fire and danger.
Yellow lines are used 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.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Lines for potable water use blue lines. Purple lines are used for reclaimed water, irrigation, and slurry lines. Green lines are used for sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
