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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. If there is a need to dig the ground, it is very important that the utility lines first be identified. 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. It can also interrupt services in your area where the line is located. People can call 811 to prevent these incidents, before they proceed with digging their property. 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. When utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. This is then something that affects public health and safety.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. When locating utility lines underground, this machine makes it easy to do so. Calling 811 is enough for the property owner to let companies located their lines.
There are certain colors that mark different utility lines for easy identification. Here are the colors used for different utilities.
Proposed excavation sites use white lines. You can mark areas with white lines that will soon be excavated.
If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
If you see red lines, then you can be sure that these are electric power lines, cable, conduit, and lighting cables. This color is appropriate for electrical works since it is associated with fire and danger.
Lines for gas, oil, steam, petroleum, and gaseous materials use the color yellow. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.
Communication, alarm, signal lines, cable, or conduit use orange lines. Blue lines are used for potable water. Purple lines are used for reclaimed water, irrigation, and slurry lines. Sewer and drain lines use the color green. You can derail any project for a long time if you hit these lines.
