Every confined space — especially those requiring a permit — should be marked clearly to alert workers before entry.
Why It Matters:
Unlabeled or poorly marked spaces increase the chances of someone entering without proper protection, training, or authorization. Signage is a critical line of defense to prevent accidental or unauthorized entry.
Key Points:
- Use bold, weather-resistant signage at all confined space entry points.
- Labels should clearly indicate:
- “DANGER – Permit-Required Confined Space – Do Not Enter”
- Specific hazards (e.g., toxic gases, engulfment)
- Entry requirements (permit, attendant, air monitoring)
- Temporary jobsite spaces (e.g., tanks, pits, crawlspaces) must also be labeled during construction.
- Train all crews to recognize and respect these labels as non-negotiable safety controls.
✅ Clear signage saves lives by stopping entry before a worker steps into danger.
Ask the Crew:
- Are all confined spaces on our site labeled?
- Would someone new on the job immediately know not to enter?
