Standard Colors for Your Underground Utilities
If you find underground utilities, you can easily determine what type of utility it 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. If there is a need to dig the ground, it is very important that the utility lines first be identified. Before digging through a certain piece of land, the OSHA requires that the underground utilities be located. Otherwise it can be something disastrous. 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. 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. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. This is then something that affects public health and safety.
GPR or Ground Penetrating Radar is used by companies to locate their 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.
It is easier to identify underground utility lines today because they now use different colors for each utility. Here are the colors used for different utilities.
White lines are for proposed excavation sites. It locates areas that will be excavated in the near future.
Pink lines 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 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. Bright yellow is an appropriate warning color since it is very disastrous to have a natural gas leak.
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. Green lines are used for sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
