strong oxidizer, will be stored in the acid locker. Oxygen, chlorine gases, and calcium hypochlorite will be stored as per the following paragraphs on calcium  hypochlorite  and  compressed  gases.  All other  oxidizers  will  be  stored  in  a  dry  compart- ment,  away  from  combustible  materials. Calcium Hypochlorite Calcium  hypochlorite  itself  is  noncombustible; however,  it  is  a  strong  oxidizing  agent  that  can generate  heat,  liberate  chlorine,  and  cause  fire when stored in contact with paints, oils, greases, detergents,  acids,  alkalies,  antifreeze,  fabrics,  and other  organic  and  combustible  materials.  Calcium hypochlorite will be stored in bins or lockers la- beled   HAZARDOUS   MATERIAL—CALCIUM HYPOCHLORITE  in  red  letters  on  a  white background.  The  bins  or  lockers  will  not  be located in an area that is used for storage of com- bustible  organic  materials,  or  is  adjacent  to  a magazine, or is subject to condensation or water accumulation. Each bin or locker must be at least 5 feet away from any heat source or surface that may exceed 140°F and will contain no more than 48 6-ounce bottles   (for   potable   water   purification)   or 36  3  3/4-pound  bottles  (for  sewage  waste  treat- ment). The total quantity stored should not exceed the  ship’s  average  endurance  level.  On  CLF  ships, calcium  hypochlorite  carried  as  cargo  should  be stored  in  a  separate  enclosure  constructed  of  steel or  expanded  metal  with  a  secured  door. If   calcium   hypochlorite   becomes   contam- inated, you can dispose of it in water or flush it into the drain or the bilge. Calcium hypochlorite is  not  a  fire  hazard  when  dissolved  even  in  an oily  bilge. Drummed Products Whether   drummed   products   on   board   are flammable liquids or nonflammable material, the drum will be stored on end with the bung end up. An adequate identification of the contents must be legibly indicated on the side of each drum. If stored  on  the  weather  deck,  they  should  be covered   with   a   tarpaulin   (when   possible). Drummed  products  will  be  inspected  at  least weekly to make sure the bungs are tight and there are  no  leaks  or  corrosion. Compressed Gases Compressed   gases   must   be   stored   on   the weather  deck  unless  the  ship  has  below-deck storage   spaces   specifically   designed   for   such material.  Compressed  gas  cylinders  will  be  stored vertically  and  securely  (with  valve  protection  caps in  place),  away  from  other  flammable  materials (especially grease and oil). When compressed gases are stored on the weather deck, the cylinders will be located as far as possible from navigation, fire control,  or  gun  stations  and  will  be  protected  from direct  rays  of  the  sun,  or  accumulation  of  snow and ice. When compressed gases are stored below decks, any leaking fumes must be prevented from entering ventilation air intakes leading to work- ing or living spaces. Since there usually is some gas remaining in most cylinders considered to be empty,   “empty”   cylinders   will   be   stored   and handled   with   the   same   precautions   as   full cylinders.   Compressed   gases,   particularly   the flammable and explosive gases, must be handled with  extreme  care.  Some  general  rules  for  han- dling  compressed  gas  cylinders  are  as  follows: . Take every precaution to prevent cylinders from  being  dropped  or  forcefully  struck  against hard surfaces (including other cylinders). Do not tamper   with   the   safety   devices   in   cylinder discharge valves and, when cylinders are not in use, be sure the valve protection caps always are securely attached. (If the valve of a compressed gas cylinder should be snapped off, the released energy  would  cause  the  cylinder  to  behave  as  a missile. For example, a cylinder that is pressurized to 2,200 pounds per square inch [psi] can travel 2,600 feet in free flight and, in a confined space, it  could  be  disastrous.) l  Prevent  cylinders  from  contact  with  fire, sparks,  or  electrical  circuits.  (An  exploded  steel cylinder would have the same destructive effect as  an  exploded  bomb.) . Do not drag or slide cylinders required to be moved. Secure and move them in hand trucks that  meet  the  criteria  prescribed  in  the  Naval Ships’  Technical  Manual,  chapter 9230. If suitable hand  trucks  are  not  available,  tilt  the  cylinders and  roll  them  on  the  bottom  edge. . Secure cylinders in a cradle, pallet, or rack when they are loaded or off-loaded with a crane or  derrick.  Never  hoist  cylinders  with  elec- tromagnets or with hooks or line attached to the valve  protection  cap. .  Do  not  alter  or  deface  the  numbers  or other markings on the cylinders; do not add mark- ings without approval of the engineer officer; and do not issue cylinders if their contents cannot be identified. 7-3
