DANGER Underground Duct Bank Sign – Do Not Excavate – 8x12 Aluminum

A duct bank is basically underground “infrastructure insurance.” It exists to protect conduit runs, keep routes organized, and make future pulls possible without tearing up the world. The problem is that, from the surface, it looks like nothing. That’s how you end up with a trench, a broken conduit bundle, a shredded pull rope, and a repair scope that balloons into traffic control, emergency locates, resplicing, and downtime.

The CGAP Safety “Danger – Underground Communications – Duct Bank – Do Not Excavate – Call 811 Before You Dig” sign is a high-visibility warning marker for buried communications duct banks and conduit corridors. The bold DANGER header and direct “DO NOT EXCAVATE” language are designed to interrupt excavation activity immediately, while the Call 811 instruction reinforces the correct next step for compliant locating and safe digging.

This sign is purpose-built for damage prevention programs, including utility coordination on construction sites, municipality corridor management, campus facilities, industrial parks, and commercial properties with buried communications pathways. It helps reduce accidental strikes that cause service interruptions, project delays, costly restoration, and preventable rework when crews dig blind or assume a route is “probably somewhere else.”

Manufactured in 8 x 12 inches from rust-resistant aluminum, it is designed for long-term indoor/outdoor deployment on posts, fences, walls, access points, or barricades near known conduit routes. The durable metal construction outlasts paper notices, laminated sheets, and thin plastic signs that warp, fade, or crack in sun and weather exposure.

Use this sign as a practical layer in your overall locate-and-protect process to keep excavation activities aligned with 811 workflows and utility coordination, before equipment goes into the ground.

Important: This product is a warning sign only and does not replace required locating/marking practices, safe excavation methods, permits, or local regulations. Always contact 811 and follow applicable site procedures before digging or excavating.
