The Importance of Colors of Underground Utility Lines
If you find underground utilities, you can easily determine what type of utility it 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. 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. Fatal injuries can happen if underground utility lines are struck. 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. 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. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. Public heath and safety is affected when this happens.
GPR or Ground Penetrating Radar is used by companies to locate their utility lines. With this machine, companies can easily locate utility lines. 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.
Proposed excavation sites use white lines. Area that will be excavated in the future are marked.
If you see pink lines, they are temporary survey markings. Surveyors use pink lines to mark off legal property boundaries.
Red lines are used to mark electric power lines, cable, conduit, and lighting cable. 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. 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. If you see purple lines, that this is 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.
