Standard Colors for Your Underground Utilities
It is now easier to know what an underground utility line is for. Before, it was difficult to do so and people were at risk if they try to make a dig without being able to identify all the lines underneath the land. Today, the risks have been lessened although not completely eliminated. 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. 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. Utility companies can then mark out their respective lines when you call them out.
Sometimes, even if the lines are marked accidents still happen. The reality is that there is an incident almost every 6 minutes where utility line are struck. When this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. This is then something that affects public health and safety.
GPR or Ground Penetrating Radar is used by companies to locate their 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.
Today, utility lines are marked with different colors for easy identification. The colors below indicate the kind of utility uses it.
Proposed excavation sites use white lines. It locates areas that will be excavated in the near future.
Temporary survey markings use pink lines. Surveyors use pink lines to mark off legal property boundaries.
Electric power lines, cable, conduit, and lighting cable use red lines. 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. Natural gas leaks can create potentially disastrous situations and this is why it is appropriate to use the bright yellow color.
Orange lines are used for communication, alarm, signal lines, cable or conduit. If you see blue lines then these are lines for potable water. Purple lines are used for reclaimed water, irrigation, and slurry 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.
