FILING  SYSTEM One of the most important aspect of an organization is  a  well  organized  and  properly  maintained  filing system. This can only be achieved with competent AKs who understand and are familiar with the Navy files in general.  Constant  personnel  and  manning  changes emphasize the need for a standardized classification system. The process for segregating and filing Navy and Marine Corps records and the single standard system of numbers, letters, or symbols used throughout the DON for categorizing and subject classifying are outlined in SECNAVINST  5210.11.  The  Navy’s  Standard  Subject Identification  Code  (SSIC)  is  a  four-  or  five-digit number that stands for the subject of the document. The Navy’s SSIC system is broken down into 13 subject groups. These major subject groups are then broken down into primary, secondary, and tertiary subdivisions. For  example,  here  are  the  subdivisions  under  general administration and management, whose major subject group is 5000. General categories use zeros. 5000 — General Administration and Management. This is an example of primary subject. — Management Programs and Techniques. The last two digits designate secondary subjects. 5210  —  Records  Management. — The last digit reflects a tertiary subject. — Filing, Maintenance, Protection, Retrieval, and Privacy Act Systems. The SSIC groups common to the AK work operations are as follows: 4000  Series  Logistics 7000 Series Financial Management 10000 Series General Material 13000 Series Aeronautical Material SECURITY OF SUPPLY DEPARTMENT SPACES Security  procedures  for  supply  department  spaces afloat and ashore are the same. The supervisors are responsible for identifying the requirements for the functions of their organizational elements and for seeing that personnel under their supervision are familiar with the   security   requirements   for   their   particular assignments. On-the-job training is an essential part of command security education. all hands are responsible for ensuring that security is maintained at all times. This section  explains  the  general  security  rules  and requirements  that  apply  to  the  supply  department spaces. GENERAL SUPPY SECURITY RULES The general supply security rules are as follows: . Materials in store will always be kept under lock and key except when the bulk of such material makes stowage under lock and key impractical. .  Supply  spaces  will  be  kept  locked  when  not attended  by  authorized  personnel. l Responsibility for the security of spaces will rest with the individual in charge of each space. l Permission for entry of persons ordinarily not authorized  to  have  access  to  supply  spaces  will  be obtained  from  the  supply  officer  or  delegated  assistant. . No supply space will be secured in such a reamer that access by use of ordinary damage control equip- ment is impeded in an emergency. . Keys to supply space padlocks will not be taken from the ship/building when the custodian goes ashore or secures from work. The keys must be returned to the key  locker. .  A  key  log  will  be  maintained  to  identify  the holders of keys removed from the key locker. l Combinations to locks will not be recorded in writing unless otherwise prescribed by higher authority. . all key padlocks will be 1 1/2-inch pin tumble type,  with  dead  bolt  either  brass  or  bronze.  The  locks will  be  keyed  individual  y  and  furnished  with  two master keys for each group and two grand master keys for each set. l  All  keyless  padlocks  will  be  the  three- combination, manipulation-resistance Type 8077A. .   Combinations   on   keyless   padlocks   will   be changed at least every 6 months. PADLOCKS AND MASTER KEYS Supply department spaces are assigned to space groupings. You will be involved with Group I spaces, which  consist  of  general  stores,  including  storerooms, special  lockers,  and  related  spaces,  except  when  other 2-11
