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. 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. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. Fatal injuries can happen if underground utility lines are struck. 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. 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. Utility lines are struck every 6 minutes, some place. When utility lines are stuck it causes disturbances in 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. This has made it easier to locate utility lies underground and other important things. Calling 811 is enough for the property owner to let companies located their lines.
