Understanding Color-Coded Flags: What Do They Mean?

When it comes to utility work, a simple glance at a colorful flag can make all the difference in preventing accidents and ensuring safety. The American Public Works Association has implemented a color-coded system for utilities, making it easy for professionals in the industry to identify what type of line or cable is running where.

But have you ever stopped to think about what those colors mean? Let's take a closer look at each one:

Red Flag: Representing electric power lines, cables, conduit, and lighting cables, this flag signals that someone is working on electrical infrastructure in the area. If you're planning to dig, it's crucial to mark these areas to avoid any potential hazards.

Yellow Flag: Indicating gas, oil, steam petroleum, or gaseous materials, this flag warns of potentially hazardous digging activities near fuel lines. It's essential to exercise caution when working around these areas and ensure that they are properly marked before starting any excavation work.

Orange Flag: Symbolizing communication, cable TV, alarm, or signal lines, cables, or conduit, this flag indicates the presence of buried wires and cables. Whether you're a professional or an amateur, it's vital to respect these flags and avoid digging near them.

Blue Flag: While not explicitly mentioned in the color-coded system, blue flags are often used to mark water, irrigation, and slurry lines. If you notice a blue flag in your yard, take note that there might be buried pipes or cables nearby.

Green Flag: In some cases, green flags may indicate the presence of phone lines or other communication infrastructure. However, it's essential to verify this information with the local utility company before starting any excavation work.

Remember, if you're planning to dig in your yard or around town, always call Digger's Hotline at (414) 259-1181 or dial 811 first to mark the areas where utilities are buried. This simple precaution can save you from potential hazards and ensure a safer working environment.

With this color-coded system, you'll be better equipped to navigate utility work and avoid costly mistakes. By recognizing the significance of each flag, you'll be able to take necessary precautions and stay safe on the job site.
