Undergoung Utilities and their Standard Colors
It is now easier to know what an underground utility line 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. Today, the risks have been lessened although not completely eliminated. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. The OSHA requires that utilities underground first be located before digging through a piece of land. 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. Before digging their property, people should call 811 to call the utility companies so that these incidents are prevented. Calling the 811 number will enable utility companies to come out and mark their respective utility lines.
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 utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. 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. Companies can locate their utility lines if any property owner calls 811.
Today, utility lines are marked with different colors for easy identification. Below are some of the colors used for different utility lines.
White lines are for proposed excavation sites. You can mark areas with white lines that will soon be excavated.
If you see pink lines, they are temporary survey markings. These are used by surveyors to mark off legal property boundaries.
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.
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. 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.
