other measures called for on the permit are still in effect. Finally only operations or work
originally approved on the permit should be conducted in the confined space.
A new permit should be issued or the original permit reissued whenever changing work

noted on the pertinent permit so that appropriate revisions to the confined space permit program
can be made.

requirements of the permit are met and it is reviewed and signed by an Entry Supervisor.
