Not every fall requires a ladder — unguarded floor holes are just as deadly as falling off a roof.
Why It Matters
A worker can fall through an uncovered hole in a split second. Once it happens, there’s no time to react.
Whether it’s a stairwell, elevator shaft, deck opening, or skylight, the right protection — either a guardrail or rated cover — can prevent a fatal incident.
Key Points
- All floor holes must be guarded or covered — no exceptions
- Covers must:
- Support twice the intended load
- Be secured and clearly labeled with “COVER” or “HOLE”
- Guardrails must:
- Be 42 inches high
- Include midrails and toe boards when tools or materials could fall
- Never remove a guardrail without approval and a site-specific fall protection plan
- Watch for missing, broken, or unsecured covers — and report them immediately
✅ If there’s a hole, block it or cover it. No exceptions.
Cover vs. Guardrail — When to Use Each
Use a Guardrail When:
- The opening is large and frequently accessed (e.g., stairwells, mezzanine edges)
- The hole will remain open for an extended period
- Workers need to work or pass near the edge regularly
Use a Cover When:
- The hole is not in active use and can be fully enclosed
- The area needs to support foot traffic or equipment
- The cover can be securely fastened and clearly labeled
Ask the Crew
- Have we verified that all floor openings are either covered or guarded today?
- Do we know the requirements for a compliant guardrail?
- Has anyone noticed missing, loose, or unlabeled covers?
