Undergoung Utilities and their Standard Colors
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. 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. You dont want something disastrous to occur. 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.
But, despite the marks, there will sill be accidents. Utility lines are struck every 6 minutes, some place. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. These incidents affect public health and safety.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. With this machine, companies can easily locate utility lines. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
