OSHA 40 Confined Space Definitions

The hazards encountered and associated with entering and working in OSHA 40 areas are capable of causing bodily injury, illness, and death to the worker. Accidents occur among workers because of failure to recognize that a confined space is a potential hazard. It should therefore be considered that the most unfavorable situation exists in every case and that the danger of explosion, poisoning, and asphyxiation will be present at the onset of entry.

Basic Terms

  • Confined Space: A space that is large enough and so configured that an employee can bodily enter and perform work. Confined spaces have limited or restricted means for entry or exit and are not designed for continuous occupancy. Confined spaces include storage tanks, bins, boilers, ventilation and exhaust ducts, pits, manholes, vats, and reactor vessels.
  • Entry: Confined-space entry begins when any part of the employee's body breaks the plane of any opening of the confined space and continues until the employee exits the confined space.
  • Lower explosive limit/lower flammability limit (LEL/LFL): The lowest percentage of a substance in the air that leads to fire or explosion.

Evaluation of Confined Spaces

Permit-Required Confined Space (PRCS). A confined space that has one or more of the following characteristics:

  • Potential to contain a hazardous atmosphere.
  • Material that has potential for engulfing an entrant.
  • Any other recognized serious safety or health hazard.
  • The space to be entered has a vertical height of 4 feet or greater.

Non-permit-required confined space (NPRCS). A space that meets the definition of a confined space but, which after evaluation, does not contain or have potential to contain any hazard capable of causing death or serious physical harm.
