Some confined spaces require more than just caution — they require a permit. You need to know the difference.
Why It Matters:
Permit-required confined spaces can contain deadly hazards like toxic gases, engulfment risks, or low oxygen. Identifying these spaces before entry is the law — and can save your life.
Key Points:
- A confined space is large enough to enter, has limited entry/exit, and isn’t designed for continuous occupancy.
- A permit is required if the space contains:
- Hazardous atmosphere (e.g. gas, vapors, low oxygen)
- Engulfment risk (e.g. grain bins, tanks)
- Internal configuration that could trap or asphyxiate
- Any other recognized serious safety or health hazard
- Common examples: tanks, vaults, pits, sewers, and some crawlspaces.
- OSHA requires an evaluation before entry to determine if the space is permit-required.
✅ If a space is permit-required, do not enter until all procedures are in place.
