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. 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. 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. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. When the number is called, you can let the utility companies come out and mark their respective 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 this happens, it affects traffic lights, wastewater pipes, telecommunication lines and more. These incidents affect public health and safety.
Companies can locate utility lines through the use of GPR or Ground Penetrating Radar. 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.
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. Legal property boundaries are marked off by these pink lines.
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. The bright color yellow is used to be a warning sign since a natural gas leak can create a potentially disastrous situation.
If you see orange lines, then you should associate this with communication., alarm, signal lines, cable or conduit. Blue lines are used 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.
