Undergoung Utilities and their Standard Colors
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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. It can also interrupt services in your area where the line is located. People can call 811 to prevent these incidents, before they proceed with digging their property. 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 this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. This is then something that affects 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. Calling 811 is enough for the property owner to let companies located their lines.
