out-of-calibration  labels,  and  out-of-commission labels to let you know when a specific switch, circuit breaker,  piece  of  equipment,  electronic  system,  or plumbing valve should be either operated with extra care or left alone. It  is  impossible  in  this  section  to  identify  all situations requiring tag-out procedures. However, we can mention a few situations that require you to tag out certain equipment:    Working Aloft or Over the Side: When you are working aloft or over the side, be sure that any equipment that could give you radiation burns or that  could  asphyxiate  you  is  turned  off  and tagged out.    Corrective Maintenance: When you are working on equipment that must have its power secured and  there  is  a  chance  that  someone  else  could inadvertently reapply power while you are still working  on  the  equipment,  the  equipment should be tagged out.    Preventive Maintenance: When the PMS MRCs or  equipment  technical  manuals  direct  you  to secure  electrical  power,  those  power  switches should be tagged out. TAG-OUT RESPONSIBILITIES Commanding  officers  are  responsible  for  the safety of their personnel and the operational readiness of  their  ship.  They  are  ultimately  responsible  for ensuring  that  their  personnel  follow  appropriate tag-out  procedures.  To  help  do  this,  they  assign authorizing  officers  who  have  the  authority  to  sign, issue, and clear tags and labels. There is usually one authorizing officer for each department, who may be a commissioned officer, a chief petty officer, or a petty officer. Your  department’s  authorizing  officer  normally has the following responsibilities:    Ensure  that  personnel  are  qualified  to  do  the work they are about to do,    Maintain tag-out logs,    Sign  and  issue  tags  and  tag-out  record  sheets, and    Clear the record sheets from the tag-out logs and destroy the tags when the work is completed. TAG-OUT DOCUMENTS There are five tag-out documents that you may use in your job as a Fire Controlman:    Tag-out logs    CAUTION Tags (NAVSHIPS 9890/5)    DANGER Tags (NAVSHIPS 9890/8)    OUT-OF-CALIBRATION  Labels  (NAVSEA 9210/6)    OUT-OF-COMMISSION  Labels  (NAVSHIPS 9890/7) This subsection discusses the first three documents in  depth.  The  last  two  documents  are  labels  that  are only used to identify test equipment that is either out of calibration or out of commission, and, therefore, need no further explanation. Tag-Out Log A   tag-out   log   is   a   permanent   log   of   the authorizations given for all tag-out actions. Preferably kept  in  a  three-ring  binder,  it  has  the  following  five sections: SECTION  1.  Section  1  contains  a  copy  of  the Equipment  Tag-Out  Bill,  found   in  Standard Organization  and  Regulations  of  the  U.S.  Navy, OPNAVINST 3120.32; and a copy of the command’s amplifying   instruction   on   equipment   tag-out procedures. SECTION    2.    Section    2    contains    the DANGER/CAUTION  Tag-Out  Index  and  Record  of Audits (OPNAV 3120/4). The authorizing officer uses this  form  to  assign  and  track  all  of  the  issued DANGER/CAUTION tags. Table 3-7 describes blocks 1 through 5 on figure 3-3. SECTION    3.    Section    3    contains    the DANGER/CAUTION   Tag-Out   Record   Sheets (NAVSEA 9210/9) that are still in effect. Figures 3-4 and 3-5 show the front and back sides of this form. SECTION  4.  Section  4  contains  the  Instrument Log  (NAVSHIPS  9890/10).  Keep  a  record  of  all  the OUT-OF-COMMISSION and OUT-OF-CALIBRATION labels issued in this log. SECTION    5.    Section    5    contains    the DANGER/CAUTION   Tag-Out   Record   Sheet (NAVSEA 9210/9). Keep the record sheets that have been cleared and are no longer in effect in this section. 3-8
