A non permit required confined space according to OSHA is a space that meets the OSHA’s requirement of a confined space but does not pose additional hazards to the occupant of the space.
Hence, this type of a confined space is a space that:
- Is large enough for an employee to enter and perform a task;
- Has limited or restricted means for entry or exit; and
- Is not designed for continuous occupancy.
but does not:
- Contain or has the potential to contain a hazardous
- Contain a material which have the potential to engulf someone who enters the space;
- Have an internal configuration that might cause an entrant to be trapped or asphyxiated by inwardly converging walls or by a floor that slopes downward and tapers to a smaller cross section; and
- Contain any other recognized serious safety or health hazards.
Any space that meets these requirements highlighted above are said to be a “Non permit required confined space”
Non-permit required confined spaces can be continually accessed by workers, but are still associated with inherent difficulties stemming from the tight spaces.
Signage is not required for these type of confined space according to OSHA, but workers should still exercise a great deal of caution.
