The Importance of Colors of Underground Utility Lines
If you find underground utilities, you can easily determine what type of utility it is for. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. Today, the risks have been lessened although not completely eliminated. 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. The worst thing that can happen if lines are not identified is that fatal injuries can happen. 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. Calling the 811 number will enable utility companies to come out and mark their respective utility lines.
Marking lines may lessen the risks but there are time when accidents still happen. Utility lines are struck every 6 minutes, some place. When utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. This is then something that affects public health and safety.
GPR or Ground Penetrating Radar is used by companies to locate their utility lines. With this machine, companies can easily locate utility lines. 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. Below are some of the colors used for different utility lines.
Proposed excavation sites use white lines. 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. This color is appropriate for electrical works since it is associated with fire and danger.
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.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Lines for potable water use blue lines. Reclaimed water, irrigation, and slurry lines used purple lines. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
