Undergoung Utilities and their Standard Colors
Underground utilities can easily be identified today. The risk was high before when people could not easily identify the type of utility lines underneath whenever they dig. There is reduced risks today because of new methods of identifying utility lines although not a complete reduction. 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. It can also interrupt services in your area where the line is located. 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 utility lines are stuck it causes disturbances in traffic lights wastewater pipes, telecommunication lines and more. These incidents affect 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. Companies can locate their utility lines if any property owner calls 811.
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. Area that will be excavated in the future are marked.
Pink lines are temporary survey markings. Legal property boundaries are marked off by these pink lines.
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. If you see purple lines, that this is for reclaimed water, irrigation and slurry lines. Green lines are used for sewer and drain lines. A project can be derailed for a long time when these utility lines are hit.
