applicable,   local   disposal   direction,   and   other selected  management  data.  The  MRIL  must  be used  in  conjunction  with  the  Supply   Afloat Packaging   Procedures,   NAVSUP   P-484,   and Afloat  Supply  Procedures,  NAVSUP  P-485,  for all  afloat  activities  and  MILSTRIP/MILSTRAP, NAVSUP P-437, and the  Material Turned In To Store (MTIS) Manual,  NAVSUPINST  4440.157, for  ashore  activities.  The  MRIL  is  published  on microfiche by the FMSO and distributed monthly to   all   ships   and   shore   activities   that   use   or process  repairable.  Each  edition  supersedes  the previous edition and the old microfiche should be discarded  except  for  the  introduction  which  is published  and  distributed  quarterly.  The  MRIL is  divided  into  two  parts.  Part  I  contains  NSNs and NICNs of repairable items and aircraft engine type/model/series   identifiers.   It   also   contains information  required  to  make  repair  or  turn-in determinations   on   repairable   and   aircraft engines. NSNs and NICNs listed in this part are in  NIIN  sequence.  Part  II  contains  addresses  of DOPs  including  contractors  and  other  indicated destinations for all items listed in part I. Addresses are listed in shipping code sequence. Items that are  either  in  long  supply  or  are  authorized  to remain  in  place  are  indicated,  and  the  NIIN  of specially  designated  reusable  shipping  containers for  returning  the  repairable  component  is identified. Hazardous Material Information System The Hazardous Material Information System (HMIS)  provides  information  to  assist  users  in managing  hazardous  materials  so  that  the  risk involved  in  the  performance  of  various  jobs  is minimized.  The  HMIS  provides  a  wide  range  of data  related  to  safety,  health,  packaging,  labeling, transportation,   and   disposal   of   hazardous material. It also provides stowage and handling safety  precautions.  The  HMIS  is  in  microfiche format and is issued quarterly by NAVSUPSYS- COM. List of Items Requiring Special Handling The List of Items Requiring Special Handling (LIRSH),   NAVSUP   P-4105,   is   published   to identify items that require special handling. The LIRSH  is  a  reference  publication  used  in  conjunc- tion  with  other  publications,  such  as  the  MRIL and/or HMIS. Categories of items listed include repairable  items,  shelf-life  items  (deteriorative  in nature), physical security code items (for special handling),  and  hazardous  items.  The  LIRSH  is published  quarterly  to  coincide  with  the  ML-N. Interim  updating  of  elements  such  as  NSN, repairable,  security,  shelf-life,  and  shelf-life action  code  data  is  provided  via  change  notice cards/tapes to all applicable activities. Distribu- tion  of  the  LIRSH  is  controlled  by  the  FMSO. Afloat Shopping Guide The Afloat Shopping Guide (ASG), NAVSUP P-4400,  is  designed  to  assist  fleet  and  all  Navy supply support personnel in identifying the NSN items that are most frequently requested by ships. It includes a detailed description of each item, a specific  code  to  designate  items  carried  by  combat logistics force (CLF) ships, and when applicable, stock  numbers  of  substitute  items,  The  ASGs  also include  specifications,  illustrations,  or  diagrams of several types of materials. The ASGs contain six  sections  as  follows: Federal  Supply  Group/ Section Federal  Supply  Class  (FSG/FSC) 1 2040 to 4930 2 5110 to 5680 3 5905 to 5990 4 6135 to 7360 5 7510 to 8470 6 9150 to 9920 To   obtain   management   data   for   those   NSNs listed, the ML-N should be consulted for current information on unit of issue, unit price, and other pertinent  supply  management  data  required  to requisition the item. This publication is updated as required. The ASG is distributed to all ships and  Navy  activities  providing  supply  support within the Navy supply system. Identification  Lists The  Identification  Lists  (ILs)  are  developed and  published  by  the  DLSC  to  provide  descriptive and illustrative data to identify or select items of supply  used  by  all  services.  Therefore,  various NSNs identified in the ILs are not listed in the ML-N.  The  ILs  are  updated  either  quarterly  or semiannually, depending on the size of each. The ILs are distributed only to shore activities, load- carrying  ships,  and  aircraft  carriers. 1-14
