Standard Colors for Your Underground Utilities
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. 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. The OSHA requires that utilities underground first be located before digging through a piece of land. It is to prevent disaster. 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. 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. It is said that every 6 minutes, there is a utility line that is struck. Traffic lights, wastewater pipes, telecommunication lines, etc. are affected when lines are struck. This is then something that affects public health and safety.
With the use of GPR or Ground Penetrating Radar, companies can locate utility lines. 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.
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. Area that will be excavated in the future are marked.
If you see pink lines, they are temporary survey markings. Surveyors use pink lines 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.
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. Purple lines are used for reclaimed water, irrigation, and slurry lines. If you see the color green, then it indicates sewer and drain lines. Hitting this line can truly derail any project for a long period of time.
