It is now easier to know what an underground utility line is for. 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. 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. 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. People can call 811 to prevent these incidents, before they proceed with digging their property. 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. These incidents affect public health and safety.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. When locating utility lines underground, this machine makes it easy to do so. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
