Permit Required Confined Space
- Any space that is large enough and so configured that an employee can bodily enter the space and perform assigned work, and has limited or restricted means for entry or exit, and is not designed for continuous employee occupancy.
- Entry into a Permit Required Confined Space requires rescue equipment (lifeline, harness, tripod, etc.)
A confined space that has one or more of the following characteristics:
- Contains, or has the potential to contain, a hazardous atmosphere.
- Contains a material that has the potential for engulfing an entrant.
- Has an internal layout such as that someone entering could be trapped or asphyxiated by inwardly converging walls or a smaller cross-section.
- Contains any other recognized serious safety or health hazard.
Non-Permit Required Confined Space
- Any space, which is completely free of hazards and can be so proven without entering the space. The entrant must be a qualified person and would be able to work alone with no safety attendant required.
- If it can be proven that hazards can be eliminated or removed through preventative measures (i.e. ventilation of space, forced air feed, lockout/tagout, etc.) then the rescue equipment will not be required. This will be determined by Environmental Health and Safety.
- A confined space includes, but is not limited to storage tanks, vessels, sub-cellars, bins, pits, boilers, sewers or underground utility vaults. A confined space can also be open-topped, especially if it is four feet or more in depth.
