Underground utilities can easily be identified today. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. 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. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. Fatal injuries can happen if underground utility lines are struck. The location of the areas where the lines were struck can experience service interruption. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. Utility companies can then mark out their respective lines when you call them out.
Marking lines may lessen the risks but there are time when accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
GPR or Ground Penetrating Radar is used by companies to locate their utility lines. 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.
It is easier to identify underground utility lines today because they now use different colors for each utility. Here are the colors used for different utilities.
Proposed excavation sites use white lines. Area that will be excavated in the future are marked.
Pink lines are temporary survey markings. Surveyors use pink lines to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. 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. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.
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. Hitting this line can truly derail any project for a long period of time.
