Undergoung Utilities and their Standard Colors
It is now easier to know what an underground utility line is for. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. 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. If you hit any of the underground utility lines while digging then you can be fatally injured. Services in the area where the lines are located can experience interruption. 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. Utility lines are struck every 6 minutes, some place. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.
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. Companies can locate their utility lines if any property owner calls 811.
Today, utility lines are marked with different colors for easy identification. Here are the colors used for different utilities.
Proposed excavation sites use white lines. Area that will be excavated in the future are marked.
Temporary survey markings use pink lines. Legal property boundaries are marked off by these pink lines.
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 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.
Communication, alarm, signal lines, cable, or conduit use orange lines. If you see blue lines then these are lines for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. You can derail any project for a long time if you hit these lines.
