If there’s a hole big enough for your boot, it’s big enough for your body — and that means a serious fall hazard.
Why It Matters
Even small floor openings can cause twisted ankles, broken legs, or serious falls.
Workers may not notice the hole — especially if they’re carrying materials, wearing shaded lenses, or working in low light.
OSHA requires all holes over 2 inches wide to be properly covered or guarded.
Key Points
- Any floor opening over 2 inches must be covered or guarded
- Covers must:
- Support twice the intended load
- Be secured to prevent movement
- Be clearly marked with “COVER” or “HOLE”
- Never assume a piece of plywood is safe unless it’s marked, rated, and secured
- If you remove a cover for any reason, put it back immediately
✅ If it’s not marked, locked down, and rated — it’s not a cover.
Cover Requirements Checklist
✅ Acceptable Covers:
- Plywood at least ¾” thick, marked and screwed down
- Metal plates designed for floor protection
- Manufactured covers approved by a competent person
- Clearly labeled “COVER” or “HOLE” in bold, visible lettering
🚫 Unacceptable Covers:
- Loose plywood, cardboard, or scraps
- Covers not secured or easily moved
- Unlabeled material that could be mistaken for trash or flooring
- Covers too thin or weak to support foot or equipment traffic
Ask the Crew
- Do we know where all current floor openings are on-site?
- Are we labeling and securing every cover properly?
- What would you do if you saw an unlabeled or loose cover?
