DANGER Sanitary Sewer Force Main Sign – Biohazard Exposure – 8x12 Aluminum

A sewer force main is not a normal gravity sewer. It’s a pressurized sanitary line, and when it gets struck, the result is not just “a broken pipe.” It can turn into a sewage release, splash and aerosol exposure, ground contamination, emergency cleanup, reporting requirements, and a jobsite shutdown that costs more in a single day than a stack of signs ever will.

The CGAP Safety “Danger – Sanitary Sewer Force Main – Biohazard Exposure Risk – Call 811 Before You Dig” sign is a high-visibility warning marker for buried sewer force mains located in municipal rights-of-way, easements, pump station routes, commercial properties, campuses, and utility corridors. The bold DANGER header and direct biohazard language are designed to create a hard pause before crews trench, bore, drive stakes, set posts, or excavate near a suspected line path.

This sign reinforces the core behavior that prevents avoidable incidents: locate before you penetrate. By pairing the line identification with a clear Call 811 instruction, it supports standard damage-prevention workflows and helps reduce strikes caused by assumptions, missing as-builts, or schedule pressure.

Manufactured in 8 x 12 inches from rust-resistant aluminum, this sign is built for long-term indoor/outdoor use where weather, UV exposure, and field wear quickly destroy temporary notices. Mount it on posts, fences, walls, or near access points where contractors and maintenance crews will see it before ground disturbance begins.

Use this sign as part of your broader utility coordination and safe-dig program to reduce sewer release risk, protect crews and the public, and keep work moving without emergency interruptions.

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 procedures before digging.
