Not every confined space looks dangerous at first — but that doesn’t mean it’s safe.
Why It Matters:
Workers are often injured or killed because they didn’t recognize the hazards before entering. You don’t always get a second chance. Recognizing early signs of a permit-required confined space can prevent a fatal mistake.
Key Points:
- Just because it’s a “routine” space (like a vault or tank) doesn’t mean it’s safe to enter.
- Red flags include:
- Strong or unusual odors
- Stale or stuffy air
- Rust or corrosion on nearby equipment (a sign of gases)
- Slippery sludge or residue inside
- Lack of airflow or visible vents
- Unlabeled confined spaces may still require a permit — when in doubt, stop and ask.
- Always refer to the site’s confined space inventory or consult the competent person.
✅ Trust your senses — if something seems off, don’t go in.
Ask the Crew:
- Have you ever entered a space that “didn’t look dangerous” but actually was?
- What signs should we watch for before approaching a confined space?
