Standard Colors for Your Underground Utilities
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. If there is a need to dig the ground, it is very important that the utility lines first be identified. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. The location of the areas where the lines were struck can experience service interruption. People can call 811 to prevent these incidents, before they proceed with digging their property. Calling the 811 number will enable utility companies to come out and mark their respective utility 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. This has made it easier to locate utility lies underground and other important things. Calling 811 is enough for the property owner 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.
White lines are for proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Pink lines are temporary survey markings. Legal property boundaries are marked off by these pink lines.
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.
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.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Blue lines are used for potable water. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. Sewer and drain lines use the color green. A project can be derailed for a long time when these utility lines are hit.
