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. 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. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. Fatal injuries can happen if underground utility lines are struck. Services in the area where the lines are located can experience interruption. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Calling the 811 number will enable utility companies to come out and mark their respective utility 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. When utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. These incidents affect public health and safety.
GPR or Ground Penetrating Radar is used by companies to locate their utility lines. This has made it easier to locate utility lies underground and other important things. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
There are certain colors that mark different utility lines for easy identification. Below are some of the colors used for different utility lines.
If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Temporary survey markings use pink lines. These are used by surveyors to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
Yellow lines are used for gas, oil, steam, petroleum, and gaseous materials. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Green lines are used for sewer and drain lines. You can derail any project for a long time if you hit these lines.
