The Importance of Colors of Underground Utility Lines
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. 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. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. 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. 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. Utility lines are struck every 6 minutes, some place. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. 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.
There are certain colors that mark different utility lines for easy identification. Here are the colors used for different utilities.
If you see white lines, then these are proposed excavation sites. You can mark areas with white lines that will soon be excavated.
Pink lines are temporary survey markings. Legal property boundaries are marked off by these pink lines.
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. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.
Orange lines are used for communication, alarm, signal lines, cable or conduit. Blue lines are used for potable water. Reclaimed water, irrigation, and slurry lines used purple lines. Green lines are used for sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
