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. 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. 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. The worst thing that can happen if lines are not identified is that fatal injuries can happen. It can also interrupt services in your area where the line is located. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. When the number is called, you can let the utility companies come out and mark their respective lines.
Sometimes, even if the lines are marked accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. When utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. Public heath and safety is affected when this happens.
GPR or Ground Penetrating Radar is used by companies to locate their 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.
Today, utility lines are marked with different colors for easy identification. Below are some of the colors used for different utility lines.
