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. 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. The OSHA requires that utilities underground first be located before digging through a piece of land. 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. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. Utility companies can then mark out their respective lines when you call them out.
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. When locating utility lines underground, this machine makes it easy to do so. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
It is easier to identify underground utility lines today because they now use different colors for each utility. The colors below indicate the kind of utility uses it.
If you see white lines, then these are proposed excavation sites. It locates areas that will be excavated in the near future.
If you see pink lines, they are temporary survey markings. 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 perfect for electric works because it is associated with fire and danger.
Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. If you see the color green, then it indicates sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
