The Importance of Colors of Underground Utility Lines
Underground utilities can easily be identified today. 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. If there is a need to dig the ground, it is very important that the utility lines first be identified. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. 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. 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. 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.
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. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
