Sinkholes and subsurface voids are unpredictable hazards that can cause sudden ground collapse. This CGAP Safety DANGER sign provides a clear visual warning: “SINKHOLE AREA – GROUND MAY COLLAPSE WITHOUT WARNING – KEEP OUT.” The red DANGER banner ensures that visitors recognize the seriousness of the hazard immediately.

 

Constructed from durable 8x12 inch .040 aluminum, this sign withstands harsh outdoor conditions and mounts easily to fences, gates, posts, or trailhead kiosks. Ideal for landowners, parks departments, excavation contractors, or anyone needing to restrict access to unstable ground.

 

  • DANGER – UNSTABLE GROUND – Warns visitors that the ground may collapse without warning due to sinkholes, subsurface voids, or erosion.
  • CLEAR “KEEP OUT” INSTRUCTION – “GROUND MAY COLLAPSE WITHOUT WARNING – KEEP OUT” helps prevent injuries and liability on private or public land.
  • 8×12 IN RUST-PROOF ALUMINUM – Industrial-grade .040 aluminum sign resists rust, UV exposure, rain, and wind for long-term outdoor posting.
  • EASY TO MOUNT ON POSTS OR FENCES – Pre-drilled holes fit screws, nails, and zip ties for quick installation at trailheads or property boundaries.
  • IDEAL FOR LANDOWNERS & PARKS – Perfect for farms, rural properties, parks, construction zones, or any area with known or suspected sinkhole activity.

Buying for a facility, municipality, or contracting business? We handle purchase orders, net terms, tax-exempt purchasing, W-9 and vendor onboarding, and written quotes.

Need a sign we do not make?

Hyper-specific signage is what we do. Most of our catalog exists because someone had a hazard that generic sign companies do not cover.

If you cannot find the right sign anywhere, describe the hazard and the wording you need. Custom and short-run work is normal for us.
