Standard Colors for Your Underground Utilities
It is now easier to know what an underground utility line is for. However, a long time ago, it was difficult to identify these utility lines and so when people try to dig there were many risks involved. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. If there is a need to dig the ground, it is very important that the utility lines first be identified. 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. The worst thing that can happen if lines are not identified is that fatal injuries can happen. 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.
But, despite the marks, there will sill be accidents. 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.
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.
