A Confine Space by design is large enough and so configured that an employee can bodily enter
and perform assigned work, has limited or restricted means for entry or exit and is not designed
for continuous employee occupancy.
A Permit-Required Confined Space has one or more of the following characteristics: contains or
has a potential to contain a hazardous atmosphere, contains a material that has the potential for
engulfing an entrant, has an internal configuration such that an entrant could be trapped or
asphyxiated by inwardly converging walls or by a floor which slopes downward and tapers to a
smaller cross-section or contains any other recognized serious safety or health hazard. Permit-
Required Confined Spaces are located throughout NCDOT with different types of hazards
associated with them. Permit-Required Confined Spaces can present dangerous hazards to
NCDOT employees who perform work activities in them.
