Marking Floor Openings Clearly

June 22, 2025

If a floor opening is covered, but not labeled or clearly visible, it’s still a major fall hazard.

Why It Matters

Workers may step on or roll equipment over a floor opening cover, thinking it’s solid ground.

If that cover shifts, breaks, or wasn’t rated properly — it can lead to a serious fall or equipment damage.

Visibility is just as critical as strength when it comes to preventing accidents.

Key Points

  • Every floor cover must be clearly marked with “HOLE” or “COVER”
  • Use bright paint, large lettering, or high-visibility tape that can be seen from a distance
  • Never stack materials on top of a cover — it hides the hazard and prevents inspection
  • If you don’t know what’s under a piece of plywood or board — treat it as unsafe until confirmed
  • Covers must also be secured and strong enough to support twice the expected load

✅ If it’s not obvious, it’s dangerous. Label it.

Common Mistakes to Avoid

🚫 Leaving covers unlabeled, especially during early framing or concrete pours

🚫 Using spray paint that fades or becomes unreadable

🚫 Storing pallets, drywall, or tools on top of floor hole covers

🚫 Covering holes with makeshift boards that aren’t secured or rated

🚫 Failing to inspect and re-mark covers after heavy rain, mud, or jobsite wear

Ask the Crew

  • Are all of our current floor covers labeled clearly and visibly?
  • Would someone walking by or pushing a cart recognize that it’s a cover?
  • Have we ever mistakenly covered a hole with materials?
