assistance  modules  (MAMs)  and  ready  service spares   (RSSs)   are   located   in   the   appropriate operating  and  maintenance  spaces  under  the  sub- custody  of  the  operating  or  maintenance personnel. RESPONSIBILITY The  supply  officer  is  responsible  for  the storage,  security,  and  inventory  control  of  all stock  material  in  his  or  her  custody. Although   stock   levels   should   be   stored   in supply department storerooms or spaces, it may be  necessary  to  store  bulk  consumables  such  as lumber,  metal,  and  pipe  or  certain  repair  parts in spaces under the control of other department heads. If it is necessary to store material in other department spaces, the supply officer will obtain the  commanding  officer’s  written  authorization for  such  storage. STORAGE  OF  PERSONAL  GEAR No  personal  gear  (regardless  of  whose  it  is) may be stored in supply department storerooms without   written   approval   of   the   commanding officer. LOST,   DAMAGED,   OR DESTROYED   MATERIAL Personnel  assigned  the  responsibility  for physical  custody  of  stock  material  must  report  any damage, deterioration, or shortage to the supply officer  immediately.  The  custodian  will  not  be held  responsible  for  material  lost,  damaged,  or destroyed as a result of fire or flooding, providing the  emergency  did  not  arise  from  that  person’s negligence and provided that all reasonable steps to  prevent  the  loss  or  damage  were  taken. SECURITY  OF  MATERIAL Material in store must be kept under lock and key in all cases except when the material is of such quantity  or  dimensions  as  to  make  storeroom storage  impractical.  Storeroom  spaces  must  be locked  securely  when  not  in  use. When   the   spaces   are   open   for   use,   an authorized person must always be present. Other persons will be admitted only when necessary for the  storage  or  breakout  of  material  or  in  situa- tions  discussed  in  the  following  paragraphs. Inspection of Spaces Personnel  may  be  allowed  access  to  storage spaces for purposes of inspection and as directed by  the  commanding  officer.  However,  such  per- sonnel may not be given keys for the spaces, but will  be  escorted  by  responsible  persons  as  directed by  the  supply  officer. Access for Damage Control Access  to  storage  spaces  may  be  authorized to damage control personnel in the performance of  their  duties.  Storage  spaces  must  be  secured in such a manner that access by use of ordinary damage  control  equipment  is  not  obstructed  in  an emergency. Permission for Entry Permission for entry to supply storage spaces of personnel not ordinarily authorized access will be  granted  only  by  the  supply  officer  or,  in  his or her absence, the commanding officer, executive officer, or command duty officer, as appropriate. MATERIAL  SURVEYS Material survey is a procedure for determin- ing the cause of gains, losses, or damage to Navy property,  establishing  personal  responsibility  (if any),  and  documenting  necessary  inventory  ad- justments   to   stock   records.   The   procedures discussed in this section are used when possible survey  action  is  indicated. When   an   inventory   adjustment   and preliminary research cannot resolve the discrepancy, the   accountable   and   responsible   individuals initiate  a  detailed  review  of  the  circumstances surrounding the possible adjustments (known as causative   research).   A   Report   of   Survey,   DD Form  200,  is  prepared  and  forwarded  to  the appropriate  survey  officials. When  the  report  of  survey  is  for  stock material, the inventory adjustments are entered into  SUADPS-RT  via  the  survey  adjustment function  only  after  approval  of  the  survey. SURVEY  REQUIREMENTS When a loss or gain of material in the follow- ing  categories  is  confirmed,  a  Report  of  Survey, DD  Form  200,  is  prepared. 3-19
