To A Non-Permit Confined Space
If a permit
space poses no actual or potential atmospheric hazards and if all
hazards within the space are eliminated without entry into the space,
the permit space may be reclassified as a non-permit confined space
for as long as the non-atmospheric hazards remain eliminated.
If it is necessary
to enter the permit space to eliminate hazards, such entry shall
be performed according to Appendix G, Confined Space Entry Procedures.
If testing and inspection during that entry demonstrate that the
hazards within the permit space have been eliminated, the permit
space may be reclassified as a non-permit confined space for as
long as the hazards remain eliminated. Note: Control of atmospheric
hazards through forced air ventilation does not constitute elimination
of the hazards.
shall document the basis for determining that all hazards in a permit
space have been eliminated, through a certification that contains
the date, the location of the space, and the signature of the person
making the determination. The certification shall be made available
to each employee entering the space. Follow the procedures outlined
in Appendix G, Confined Space Entry Procedures for procedures to
certify a space as non-permit and Appendix H, Confined Space Entry
Form for Non-Permit Confined Space Certification.
If hazards arise
within a permit space that has been declassified to a non-permit
confined space under this section, each employee in the space shall
exit the space. The Department shall then reevaluate the space and
determine whether it must be reclassified as a permit space, in
accordance with other applicable provisions.
