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 replacement. 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. ENFORCEMENT 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. SHIP-TO-SHOP WORK 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 ship’s 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 ship’s force will disassemble the pump  and  remove  the  shaft.  Then  the  shaft  and  any necessary  blueprints  or  technical  manuals  are  delivered 1-18
