issued. The new tag is issued using the next number in
the tag-out record sheet. The authorizing officer should
sign the tag-out record sheet to authorize the clearing of
damaged or missing tags and to authorize their
3. ISSUING AND REMOVING LABELS. Labels
are issued and removed in a manner similar to that
required for tags.
a. The authorizing officer authorizes the use of
labels by signing the label and the instrument log. When
labels are required for reactor plant systems and reactor
plant support systems, the repair activity representative
concurs by signing on the label and in the instrument log
next to the signature of the authorizing officer.
b. Second check signatures are not required on
the label or on the instrument log.
c. When a label like one of those shown in
figures l-8 and l-9 is assigned, it must be affixed to the
exterior surface of the affected instrument, so operators
can easily determine the status of the instrument.
d. A different procedure is used for installed
instruments not associated with propulsion plants on
nuclear-powered ships and for portable test and radiac
equipment. In these cases, the labels shown in figures
l-8 and l-9 may be replaced by those affixed by a
qualified instrument repair or calibration facility.
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
4. Checks and audits of all tag-outs are usually
performed every 2 weeks.
5. Results of audits are reported to the responsible
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
Remember, always insist on proper tag-out. It helps
to prevent accidents, both minor and major.
Many repair jobs are designated by the ship or
approved by the repair activity as ship-to-shop jobs.
In this type of job, the ships force does a large part of
the repair work For example, the repair or renewal of a
damaged pump shaft might well be written up as a
ship-to-shop job. The ships force will disassemble the
pump and remove the shaft. Then the shaft and any
necessary blueprints or technical manuals are delivered
