Undergoung Utilities and their Standard Colors
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. Although not completely eliminated, risks today have been reduced. In order to prevent harm, it is important to know or identify these utility lines if your need to dig the ground. If you need to dig through a piece of land today, you are required by the OSHA to first identify or locate underground utilities. You dont want something disastrous to occur. The worst thing that can happen if lines are not identified is that fatal injuries can happen. 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. Calling the 811 number will enable utility companies to come out and mark their respective utility lines.
But, despite the marks, there will sill be accidents. 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. With this machine, companies can easily locate utility lines. 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. The colors below indicate the kind of utility uses it.
If you see white lines, then these are proposed excavation sites. Area that will be excavated in the future are marked.
Pink lines are temporary survey markings. These are used by surveyors 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.
Yellow lines are used 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. Green lines are used for sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
