What Is a Permit-Required Confined Space?

SafetyToolbox Talks

A confined space is large enough for a worker to enter and perform work, has limited or restricted means of entry or exit, and is not designed for continuous occupancy. When certain hazards are present, the space becomes permit-required, and entry is tightly controlled.

What Makes a Confined Space Permit-Required?

A confined space is classified as permit-required if it contains one or more of these hazards.

  • Potential toxic gases such as hydrogen sulfide or carbon monoxide
  • Oxygen deficiency
  • Flammable gases or vapors
  • Airborne dust that could explode
  • Engulfment hazards such as water, sand, or sawdust
  • A shape or layout that could trap or asphyxiate a worker
  • Exposed electrical components, moving machinery, or extreme temperatures

What Does a Permit-Required Confined Space Program Include?

When those hazards are present, a written permit program is required.

  • Atmospheric testing
  • Lockout/tagout procedures
  • A rescue plan
  • Defined entrant and attendant roles
  • Proper signage and communication

Only trained and authorized individuals may enter permit-required confined spaces.
