Identifying Permit-Required Confined Spaces

Toolbox Talk:

Look for Warning Signs of Permit Spaces

June 26, 2025

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?
