soldering  irons,  cutting  torches,  and  uncovered  lights are included in this category. When work requiring the use  of  flame,  heat,  or  spark-producing  devices  is urgently  required  in  or  adjacent  to  an  ammunition stowage  space,  follow  the  procedures  outlined  in OPNAVINST   8023.2   (series)   and   OPNAVINST 8023.21  (series). 5.  Emphasize  safety  precautions  applicable  to in-service ammunition items or equipment by using applicable signs throughout the ship. Signs may be obtained as Cog I material. They are indexed in Section 13 of Navy  Stock  List  of  Forms  and  Publications— Cognizance Symbol I, NAVSUP Publication 2002, or when not listed in NAVSUP 2002, you may obtained them from a tender-type ship by submission of a work order. 6. Emergency drills requiring the use of the general alarm system, ship’s bell or whistle aren’t conducted aboard ship while moored to an ammunition-activity pier, unless specific approval for such drills has been granted by the commanding officer of the ammunition activity. Similarly,  such  emergency  drills  aren’t  conducted by  ships  nested  together  or  at  a  pier  where ammunition-handling operations are in progress, or by a  ship  underway  during  an  ammunition  handling evolution. 7.  Ammunition  evolutions  involving  direct  contact with  ammunition  components  are  curtailed  during  local atmospheric disturbances, such as thunderstorms or high   winds.   Operations   aren’t   resumed   until nonhazardous conditions prevail. 8. Stowage of privately owned ammunition and small arms is permitted aboard ship if approved by the commanding officer. This type of stowage is subject to the security requirements of chapter 700 of the Naval Ships Technical Manual, Ammunition Handling and Stowage, NAVSEA S9086-XG-STM-000. 9. Ships and craft entering commercial or naval shipyards  for  periods  longer  than  6  weeks  are completely  offloaded  of  all  ammunition,  except  the small arms ammunition that the commanding officer considers necessary for the maintenance of security aboard ship and inert ordnance items such as bomb fins. If a ship is expected to remain in the yard for less than 6 weeks, the ship offloads, as a minimum, all ammunition  or  explosives  that  can’t  be  stowed  in sprinkler-protected  or  floodable  spaces. 10.   The   number   of   personnel   engaged   in ammunition  and  explosive  handling  operations  is limited to the minimum necessary for safe and efficient performance  of  the  work.  Unauthorized  personnel aren’t permitted in a magazine, missile handling or testing area, or at any handlng operation involving explosives  or  ammunition.  Visiting  personnel  are accompanied by a responsible escort. 11. As a general rule, any pyrotechnic device that is armed   and   otherwise   prepared   for   launching   or activating  but  hasn’t  been  used  may  be  dearmed, restored to its original packing, and returned to stowage. The exceptions to this rule are Mk 25 and Mk 58 marine location  markers,  Mk  48  decoy  flares,  and  aircraft parachute flares. If such devices can’t be made safe beyond question, they must be stowed in lockers or disposed of according to current directives. 12.  When  the  temperature  in  a  magazine  containing gas  generators,  propelling  charges,  or  fixed  ammunition reaches 110°F or above, certain actions must be taken to preserve safety and stability of the explosives. When the magazine temperature is between 110°F and  120°F,  the  magazine  should  be  artificially  cooled, as practical. The number of hours and the maximum temperature  reached  during  each  hour  of  exposure above 110°F, but less than 120°F, must be recorded. When the cumulative total number of hours of exposure to these temperatures reaches 500 hours, the ammuni- tion  must  be  expended  or  turned  into  an  ammunition activity, stating the reason for return, If the ammunition was subjected to these temperatures for less than 500 hours,  it  should  be  expended  during  subsequent  firings. When the magazine temperature is between 120°F and  130°F,  the  magazine  should  be  artificially  cooled, as practical. A special record of the number of hours of exposure and the maximum temperature reached each hour should be made. When a cumulative total of 100 hours of exposure above 120°F is reached, prior to a cumulative  total  of  500  hours  of  exposure  between 110°F and 130°F, the ammunition must have priority for expenditure or be turned in to an ammunition storage activity at the first opportunity. At  temperatures  above  130°F,  the  ammunition should be removed from the magazine and turned in to the  nearest  ammunition  activity.  When  there  is  no storage activity immediately available and the ship is in port, the ammunition may be retained on board in a segregated  magazine  or  in  a  ready-service  room  or locker. All possible methods should be used to lower the temperature of the ammunition until the ship is able to turn it in to the nearest ammunition activity. 12-25
