The Importance of Colors of Underground Utility Lines
It is now easier to know what an underground utility line is for. 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. It is thus important that we know how to identify these underground utilities if there is a need to dig the ground so that you can prevent harm. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. The worst thing that can happen if lines are not identified is that fatal injuries can happen. Services in the area where the lines are located can experience interruption. To prevent these types of incidents, it is important for property owners to call 811 so utility companies can identify their undergoing lines. Utility companies can then mark out their respective lines when you call them out.
But, despite the marks, there will sill be accidents. It is said that every 6 minutes, there is a utility line that is struck. When utility lines are stuck it causes disturbances in 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. This has made it easier to locate utility lies underground and other important things. 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. Below are some of the colors used for different utility lines.
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.
Electric power lines, cable, conduit, and lighting cable use red lines. 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.
If you see orange lines, then you should associate this with 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. Sewer and drain lines use the color green. Hitting this line can truly derail any project for a long period of time.
