INSPECTION AND AUDIT OF LOGS
Inspection and Audit. A check of active tags or labels and an audit of the Tag-Out Log
shall be conducted as described herein:
The cognizant department head is responsible for ensuring that checks and audits of
all tag-outs are performed once every two weeks. It is recommended that
abbreviated audits also be conducted as part of routine watch relief.
All active tags/labels listed in the Tag-Out Log shall be checked as correctly
installed by visual comparison of the information on the Tag-Out Record
Sheet, Tag-Out Index, and the Instrument Log with the tag/label and on the
item on which the tag is posted. When a valve or switch position is
prescribed, a visual check that the item is in the tagged position/condition will
be made unless removal of a cover, cap, or closure is required. No operation
of a valve or switch is authorized as part of a routine tag-out audit.
Authorizing Officer's should perform a spot check of installed tags to ensure
that tags so checked are effective, that is, covered by an active Tag-Out Log
entry, and take corrective action.
