The Importance of Colors of Underground Utility Lines

It is now easier to know what an underground utility line is for. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. Although not completely eliminated, risks today have been reduced. 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. 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. Utility companies can then mark out their respective lines when you call them out.

But, despite the marks, there will sill be accidents. Utility lines are struck every 6 minutes, some place. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. 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. Calling 811 is enough for the property owner to let companies located their lines.

If you see yellow lines, then they are lines for gas, oil, steam, petroleum, and gaseous materials. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.

Communication, alarm, signal lines, cable, or conduit use orange lines. If you see blue lines then these are lines for potable water. Reclaimed water, irrigation, and slurry lines used purple lines.
