Reclassification 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.

The department 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.
