2
Does
the space have limited or restricted means
for entry and exit?
3
Is
the space designed for occupancy?
Note
to the Employer: Refer to Section II for
additional clarification and assistance.
If the answers to items 1 and 2 are yes
and item 3 is no, then the space is not
considered a confined space and no further
action is needed. If the answers to items
1,2 and 3 are yes, then you have identified
the space as a confined space. Continue
to Part II if a confined space has been
identified to determine if it is a permit-required
confined space.

there any operations conducted near the
space opening which could present a hazardto
entrants?

used in the space?
18
Is
welding, cutting, brazing, riveting, scraping
or sanding going to be performed in the
space?
19
Is
electrical equipment located in or required
to be used in the space?
20
Does
the space have poor natural ventilation
which would allow an atmospheric hazard
to develop?

the space present a hazard other than those
noted above which would make it a permit
space?
Note
to the Employer: If any of the questions
in Part II have been checked Ayes@, the
confined space is a permit-required confined
space. As such, entry into these spaces
must be performed under the protection
of a full permit-required confined space

alternative procedures or reclassifying
to a non-permit space may be possible
in lieu of a full permit-required confined
space program.

to the Employer: The above listed isolation
techniques are generally used in combination
to ensure elimination of the hazard(s).

yes, then the entry must be performed
in accordance with a full PRCS program,
paragraphs (d) through (k).
Y
N
Note
to the Employer #2: Permit spaces that
contain or have the potential to contain
hazardous atmospheres may also be reclassified
as non-permit spaces if the source of
the hazardous atmosphere can be eliminated
during the entire entry operation. After
the space is isolated, purged and ventilated
from outside, it must be entered to test
the atmosphere and inspect conditions
within the space in order to ensure that
the hazards have been eliminated. This
entry must be conducted in accordance
with the full permit space program requirements
given in paragraphs (d) through (k). Once
again, control of a hazardous atmosphere
is not the same as its elimination. This
reclassification would also be valid only
as long as the hazards remain eliminated.

Has
a procedure been instituted to re-evaluate
the space and reclassify it back to a

not prohibit the host employer from requiring
a contractor to use the host employer's
permit program, nor does it require the
contractor to use the host's program.
The employer may choose to condition its
contract on the contractor's compliance
with the host's program.
