Tag-out logs are kept in the spaces designated. Supervisory watch standers must review the logs during watch relief. They must also check outstanding tags and labels and conduct an audit of the tag-out log as described in the following list. The authorizing officer must ensure that the checks and audits are performed at the required frequency and that the results are reported to the cognizant officer.

1. All outstanding tags listed on each tag-out record sheet must be checked to ensure they are installed correctly. This is done by comparing the information on the tag with the record sheet and the item on which each tag is posted. When a valve or switch position is prescribed, a visual check of the item is made unless a cover, cap, or closure must be removed. Checking the operation of a valve or switch is not authorized as part of a routine tag-out audit. A spot check of installed tags must be conducted to ensure the tags are effective; that is, that they are covered by an active tag-out record sheet. All discrepancies in actual position must be reported at once to the responsible watch/duty officer before the tag audit is continued. The date, time, type of discrepancies (including corrective action), and signature of the person conducting the check must be logged on each tag-out record sheet.

2. All outstanding tag-out record sheets must be audited against the index/audit record section. As part of the audit, each tag-out record sheet should be checked both for completeness and to ensure that the installed tags were checked. The date, discrepancies noted, and the signature of the person conducting the audit must be logged by a line entry in the index/audit record section of the tag-out log.

3. The installation of instrument labels and the auditing of logs must also be checked. A line entry made in the instrument log containing the date, the time, the discrepancies noted, and the signature confirms the check

4. Checks and audits of all tag-outs are usually performed every 2 weeks.

5. Results of audits are reported to the responsible department head.

The responsible department head should frequently check the tag-out log, note errors, and bring them to the attention of the persons responsible. This is to ensure that tag-out/label procedures are being enforced properly. Completed tag-out record sheets and instrument logs should be removed after the review. A violation of any tag-out compromises the entire tag-out system and may have serious consequences.

Therefore, strict adherence to the tag-out procedure, without exception, is required of all personnel.

1. Labels must be removed immediately when the affected instrument has been satisfactorily repaired, replaced, aligned, or calibrated.

2. Tags, which have been removed, must be destroyed.

Remember, always insist on proper tag-out. It helps to prevent accidents, both minor and major.
