similar aids in expediting internal routing may be  used  in  addition  to  the  organization address. For  correct  mailing  addresses,  consult,  as applicable,   either   the   current   issue   of   the Standard   Navy   Distribution   List,   Part   1, which  contains  the  official  list  of  fleet  and mobile   units and   their administrative addresses,  or  the  current  issue  of  the  Catalog of  Naval  Shore  Activities,  Part  2,  Standard Navy  Distribution  List.   As  the  title  suggests, Part   2   contains   the   official   list   of   shore activities with complete administrative addresses. The  inner  envelope  or  container  must show  the  address  of  the  receiving  activity. An  outer  envelope  or  container  must  show the   complete   and   correct   address   and   the return   address   of   the   sender.   However,   the address   may   be   omitted   from   the   outer enclosure  for  shipment  in  full  truckload  or carload  lots. Care  must  be  taken  to  make  sure  that classified   material   intended   only   for   the United  States  elements  of  international  staffs or  other  organizations  is  addressed  specifically to  those  elements. STOWAGE Classified   material   is   stowed   only   at locations   where suitable   facilities   are available.  The  Security  Manual   details   the requirements for storing material at each level of   classification. Do  not  store  valuables  such  as  money, jewelry,  or  precious  metals  in  the  same containers  as  classified  material. They increase  the  risk  of  a  container  being  illegally opened  or  stolen. For  emergency  purposes,  the  identity  of persons  having  access  to  the  container  and  a symbol   indicating   the   relative   priority   of destruction  are  posted  on  the  container.  In  no case,   however,   should   the   level   of   classified material  inside  the  container  be  shown. DESTRUCTION   OF   CLASSIFIED MATERIAL Classified  material  must  be  destroyed  by burning,  melting,  shredding,  or  other  forms  of mutilation  that  prevent  reconstruction  of  the material. RECORDS   OF   DESTRUCTION Top  Secret  and  Secret  material  destruction must   be   recorded.   Use   Classified   Material Destruction,  OPNAV  Form  5511/12,  or  any other   type   of   record,   as   long   as   it   includes space   for   complete   identification   of   the material, number of copies destroyed, and date of  destruction. Top   Secret   and   Secret   material   requires two   officials   to   witness   the   destruction   and sign the   destruction   report.   Officials responsible  for  destruction  must  have  a clearance equal to or greater than the material being  destroyed.  The  record  of  destruction  is kept  on  file  for  2  years. When  Top  Secret  and  Secret  material  is placed  in  a  burn  bag  for  central  destruction, the   witnessing   official(s)   should   sign   the destruction   record   when   the   material   is actually  placed  in  the  bag.  Burn  bags  are afforded  the  same  protection  as  the  highest level   of   material   they   contain   and   must   be handled  by  appropriately  cleared  personnel. SECURITY   VIOLATIONS Whether  intentional  or  not,  and  whether material  is  compromised  or  not,  the  fact  that a   procedure   was   not   followed   or   was performed  incorrectly  and  could  have  caused damage  places  the  person  responsible  in  line for   disciplinary   action. Safeguarding classified  material  is  a  daily  priority. 8-10
