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. Although not completely eliminated, risks today have been reduced. 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. You dont want something disastrous to occur. If you hit any of the underground utility lines while digging then you can be fatally injured. The location of the areas where the lines were struck can experience service interruption. 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. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. These incidents affect public health and safety.
