Standard Colors for Your Underground Utilities
If you find underground utilities, you can easily determine what type of utility it 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. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. It is to prevent disaster. 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. 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. Utility lines are struck every 6 minutes, some place. 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. This has made it easier to locate utility lies underground and other important things. Calling 811 is enough for the property owner to let companies located their lines.
Today, utility lines are marked with different colors for easy identification. Below are some of the colors used for different utility lines.
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. Surveyors use pink lines 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. The color red is associated with fire and danger so it is just appropriate to use it for electrical works.
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.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. Blue lines are used for potable water. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. If you see the color green, then it indicates sewer and drain lines.
