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. Although not completely eliminated, risks today have been reduced. 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. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. Otherwise it can be something disastrous. Fatal injuries can happen if underground utility lines are struck. 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.

Sometimes, even if the lines are marked accidents still happen. Utility lines are struck every 6 minutes, some place. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
