(1) Ensure that the purpose of the existing record sheet remains unchanged by the new work and its  associated  tags. (2)   Fill out the tag-out record sheet to reflect the  added  work.  Prepare  whatever  additional  tags  are required. Review the reason for the tag-out, the hazards involved,  the  amplifying  instructions,  and  the  work necessary  to  clear  the  tags.  Do  this  on  the  existing tag-out record sheet to ensure that it reflects the old work and the new work being added to the record sheet. After completing the review of the record sheet, have the petty officer  in  charge  of  the  work  sign  the  first  coverage check block next to the added work item. (3)  Number  each  tag  added  to  the  existing tag-out sequentially, beginning with the number after the last number in the original tag-out. Annotate the serial numbers of the new tags next to the associated new work item on the record sheet. Enter the updated number of effective tags at the top of the record sheet by crossing through  the  previous  number  and  writing  in  the  new number. (4)   After the new tags and the tag-out record sheet have been filled out and signed by the petty officer in  charge  of  the  work,  have  a  second  person  make  a review.  The  second  person  makes  an  independent  check of the tag coverage and usage by referring to appropriate schematics and diagrams. This person should sign the record sheet in the block for the new work item to show satisfaction with the completeness of the tag-out actions. This  includes  both  the  additional  and  the  previously issued  tags. (5)   Request that the authorizing officer and, when required, the repair activity representative review the entire record sheet and the new tags for completeness and  accuracy.  They  should  then  sign  their  respective blocks for the added work item. The authorizing officer will then issue the tags. j.  Do  not  allow  work  to  start  until  all  the DANGER tags required for the protection of personnel or   equipment   have   been   attached   according   to established   procedures. 2.   REMOVING   DANGER   AND   CAUTION TAGS.   Remove   these   tags   immediately   after   the situation  requiring  the  tag-out  has  been  corrected.  As each work item identified on the tag-out record sheet is completed,  delete  it  from  the  tag-out  record  sheet. Completed  work  items  listed  in  the  Operations/Work Items Included in Tag-Out section of the record sheet must  be  signed  off.  This  is  done  by  the  authorizing officer  (and  repair  activity  representative,  when required)   in   the   designated   signature   block.   All DANGER tags must be properly cleared and removed before  a  system  or  portion  of  a  system  can  be operationally tested and restored to service. To remove individual  tags,  the  authorizing  officer  must  ensure  that the  remaining  tags  provide  adequate  protection  for work,  testing,  or  operations  that  still  remain  to  be performed.  Tags  may  only  be  removed  following  the signed authorization of the authorizing officer. When a tag-out  action  was  initiated  by  a  repair  activity,  an authorized  representative  of  that  repair  activity  must concur that the job is complete. A shop supervisor or equivalent  must  sign  the  tag-out  record  sheet  before  the tags  may  be  removed.  As  the  tags  are  removed,  the date/time of removal must be initialed. Ditto marks are not allowed. All tags must be returned immediately to the  authorizing  officer.  This  officer  then  requires  a system  lineup  or  a  lineup  check  Tags  that  have  been removed  must  be  destroyed  after  they  have  been delivered to the authorizing officer. All tags associated with  each  specific  tag-out  action  must  be  destroyed  and the system or component returned to normal operating (shutdown) condition. The authorizing officer must then certify these actions by entering the date and time when the system lineup or lineup check was completed. In a case  where  a  system  or  component  restoration  was performed according to a specific document, reference to that document is made in the Condition Prescribed By block  Inapplicable  portions  of  the  statements  on  the record  sheet  are  lined  out  and  initialed  when  a  valve lineup check is not required or when the system is not returned to a normal condition. The authorizing officer must   also   enter   the   date   and   time   cleared   on   the appropriate line of the tag-out index/audit record. The completed  record  sheets  must  be  removed  from  the effective section of the log and placed in the completed section,  They  will  be  reviewed  and  removed  by  a designated   officer.   On   ships   having   a   DCC,   the authorizing officer must notify DCC that the tag-out has been cleared. To complete the process, the authorizing officer must annotate the completed tag-out record sheet in the lower right-hand corner on the reverse side with the words DCC notified, and then initial it. a.  When  any  component  is  tagged  more  than once, the DANGER tag takes precedence over all other tags. All DANGER tags must be removed and cleared before  the  equipment  may  be  operationally  tested  or operated. b.  A  missing  or  damaged  tag  is  reissued  by indicating  on  the  tag-out  record  sheet,  on  the  line corresponding to the damaged or missing tag, that the tag was missing or damaged and that a replacement was 1-17
