The Importance of Colors of Underground Utility Lines
It is now easier to know what an underground utility line is for. 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. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. 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. 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. It is said that every 6 minutes, there is a utility line that is struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.
