Control and Utilization
locker  is  not  available,  acid  bottles  must  be  stored in  the  flammable  liquids  storeroom;  but,  in  this case, the deck and the lower part of the bulkhead must be covered with a watertight rubber lining, and a label inscribed ACID BOTTLE STORAGE in  3/8-inch  letters  must  be  securely  attached  to the outside of the storeroom door. Corrosive acids are acute fire hazards and, therefore, should be stored  separately  from  oxidizing  or  flammable materials.  Corrosive  acids  (or  vapors)  must  not be  allowed  to  come  in  contact  with  the  skin  or eyes. SKs who store or issue these acids should wear  rubber  gloves,  rubber  aprons,  and  goggles (as  necessary)  to  protect  themselves  and  their clothing  from  acid  burns. METALS Bar  stock,  sheet  metal,  angle  iron,  tubing, pipe,  and  other  metals  must  be  kept  in  racks specifically  designed  for  the  storage  of  such metals. The racks should be installed fore and aft to minimize shifting of the stored material when the ship is underway. Polished sheet metal and aluminum  tubing  are  easily  scratched  and  dented and,  therefore,  must  be  carefully  handled  and secured in the rack. Gloves should always be worn when handling metals to protect the hands from injury  and  to  protect  certain  metals  (with  polished surfaces) from acid stains that can be caused by perspiration.  When  possible,  noncorrosive  grease- proof material will be used to separate dissimilar metals required to be stored together, inasmuch as  direct  contact  between  different  metals  may cause  corrosion  due  to  electrolysis. Since any required re-identification of metals by  chemical  analysis  is  often  impractical  or  too costly, many metals that lose their identification markings  are  likely  to  become  unusable  assets and, in effect, lost to the supply system. Positive identification of metals to be used in high-pressure steam systems (or other critical shipboard systems) is absolutely necessary. Therefore, it is essential that the correct NSN, specification markings, and the manufacturer’s markings (when appropriate) are  legibly  indicated  on  each  piece  of  metal  in storage and on each piece of metal issued for use. SHELF-LIFE  MATERIAL Consistent  with  established  Department  of Defense policy concerning the identification, con- trol,  and  use  of  shelf-life  items,  procedures  for the  proper  management  of  such  material  are prescribed  in  the  following  paragraphs.  These procedures  are  prescribed  to  reduce  the  large financial  losses  experienced  throughout  the  supply system incident to nonuse of deteriorative items before their shelf-life expiration dates and to make sure overaged materials (that may be ineffective or   unsafe)   are   not   installed   in   shipboard equipments.   Effective   attainment   of   shelf-life material control depends primarily on the efforts of   storeroom   personnel. To  facilitate  periodic  screening  of  shelf-life items, see the NAVSUP P-485. Applicable stock records   (and   NAVSUP   Forms   1075,   if   main- tained)  should  be  annotated  or  otherwise  iden- tified  to  indicate  the  proper  shelf-life  code. Shelf-life  codes  currently  assigned  to  applicable NSNs in the ML-N are listed in the appendixes of  the  NAVSUP  P-485. Marking of Stock Per  established  supply  distribution  systems procedures,   shelf-life   items   issued   by   ashore supply  activities  or  delivered  direct  by  contractors will  be  marked  (on  the  unit  package,  exterior  con- tainer,  or  material  itself)  as  follows: TYPE   I   SHELF-LIFE   ITEM DATE   (MANUFACTURE/CURE/ ASSEMBLY) EXPIRATION   DATE or TYPE   II   SHELF-LIFE   ITEM DATE   (MANUFACTURE/CURE/ ASSEMBLY) INSPECTION/TEST   DATE EXTENDED   EXPIRATION   TEST DATE Type  I  (nonexpendable  shelf-life)  items  are those  for  which  shelf-life  action  code  UU  is  in- dicated  on  the  latest  applicable  NAVSUP  Form 796. Refer to the NAVSUP P-485. All other shelf- life   action   codes   except   00   (nondeteriorative) apply  to  type  II  (extendable  shelf-life)  items.  Cur- rent onboard stocks of shelf-life material should be  screened  and,  insofar  as  practical  and  nec- essary, each item should be marked to show the type I or type II shelf-life data described herein. 7-5
