l l l l l l l l l Locate light, bulky material in storerooms with a high overhead clearance (to maximim the use of  available  space). Segregate  materials  that  are  similar  in  type  or classification  (for  example,  hazardous/ nonhazardous,   large/small,   shelf-life/nonshelf- life). Locate frequently requested material as close as possible  to  the  point  of  issue  and  in  storerooms that  are  most  convenient  to  maintenance personnel. Locate shelf-life items in a readily accessible area to facilitate periodic screening. Install appropriate stowage aids in spaces in which they can be effectively used. Provide for aisles that are at least 30-inches wide between bins, racks, and/or cabinets. Arrange  materials  with  identification  labels facing outward to facilitate issue and inventory. Place  hazardous  materials  in  designated  storage areas,  segregated  by  compatibility  and  hazard. Avoid, as much as possible, for the same item. ^- MATERIAL IDENTIFICATION multiple  locations Storeroom custodians should make sure that all items in stowage are legibly marked, tagged, or labeled with  a  stock  number,  Navy  Item  Control  Number (NICN),  or  other  appropriate  identification  markings. When   necessary,   technical   assistance   from   other departments may be requested to determine proper identification   of   unmarked   or   illegibly   marked materials.  Items  that  cannot  be  identified  must  be turned in ashore for disposition. Hazardous materials that are missing labels or are not properly labeled with the name of the material, hazard of the material, and name and address of the manufacturer, should be refused receipt. Containers of hazardous material obtained through open purchase should   be   accepted   only   if   they   contain   a manufacturer’s label with the name of the material, hazard of the material, and name and address of the manufacturer.  The  afloat  or  base  Hazardous  Material Coordinator   will   be   contacted   if   any   hazardous materials in storage are discovered to be lacking proper labeling. MATERIAL  PROTECTION LEVELS Material procured for the Navy is provided the degree  of  preservation,  packaging,  and  packing specified by the cognizant inventory manager to the extent   necessary   to   protect   the   material   from deterioration  and  damage  during  shipment,  handling, and stowage. For definitions of specified protection levels  and  descriptions  of  codes  marked  on  unit packages and exterior shipping containers, you should refer to Supply Afloat Packaging Procedures,  NAVSUP P-484.  You  should  also  refer  to  this  publication  to determine adequate protection of ready for issue (RFI) materials  and  unserviceable  mandatory  turn-in repairable to be transferred to another activity. STOWAGE LOCATION SYSTEM The general storeroom layout is basically the same on each ship; that is, the storerooms are numbered or lettered in sequence beginning with storeroom forward on  the  starboard  side,  and  progresses  from  starboard  to port,  upper  level  to  lower  level,  and  bow  to  stem.  The locations  within  a  storeroom  are  generally  numbered with  the  numbering  system  being  uniform  in  all stowage  spaces. The  location  of  each  item  in  stock  will  be maintained  on  tape  in  the  Shipboard  Uniform Automated   Processing   System   (SUADPS)   master record file (MRF) and printed as part of the master stock status  and  locator  listing  (MSSLL).  The  maximum number of locations for one item listed in the MSSLL is  four.  Each  location  will  be  designated  by  a five-character  alphanumeric  number  (for  example, Al  238),  except  when  the  configuration  of  the  storage area or physical characteristics of the material dictate an alternate system. Instructions applicable to records for  stock  material  located  in  other  departmental  spaces can be found in chapter 6 of Afloat  Supply  Procedures, NAVSUP   P-485. STOWAGE   AIDS Consistent  with factors,  storerooms the stowage criteria and layout are  outfitted  with  bins,  racks, shelving,   lockers,   drawer   cabinets,   deck   grating, battens, and or other stowage aids best suited for the types and quantities of material to be stowed. Refer to chapter  4  of  NAVSUP  P-485  for  illustrations  of different  types  of  stowage  aids  used  afloat.  When stowage aids need to be modified or relocated, or when additional aids must be manufactured by a repair ship 2-13
