The Importance of Colors of Underground Utility Lines
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. 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. It is to prevent disaster. If you hit any of the underground utility lines while digging then you can be fatally injured. The location of the areas where the lines were struck can experience service interruption. 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. It is said that every 6 minutes, there is a utility line that is struck. 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. With this machine, companies can easily locate utility lines. However, for the ordinary homeowner, it is enough to simply call 811 to be able to let companies located their lines.
Today, utility lines are marked with different colors 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.
Temporary survey markings use pink lines. Legal property boundaries are marked off by these pink lines.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. This color is appropriate for electrical works since it is associated with fire and danger.
If you see yellow lines, then they are lines 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.
Communication, alarm, signal lines, cable, or conduit use orange lines. Lines for potable water use blue lines. Reclaimed water, irrigation, and slurry lines used purple lines. If you see the color green, then it indicates sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
