minimum temperatures, a bimetallic thermometer with a maximum index pointer only is also acceptable. MAGAZINE TEMPERATURE LOG A Magazine Temperature Record Card (fig. 11-7) is   located   in   each   magazine.   It   is   posted   near   the thermometer for recording daily magazine temperatures. These cards are replaced on the first day of each month. The completed cards are removed from the magazine, and the temperatures for each month are posted in a permanent log. The Magazine Temperature Record Cards are retained on file for a period of 1 year. When recording magazine temperatures in the permanent log, record temperatures in excess of 100ºF so  they  stand  out  (use  red  ink).  If  the  temperature exceeds 110ºF in smokeless powder, rocket motor, and JATO  magazines,  check  the  temperature  hourly  and record   it   in   a   separate   notebook.   Transfer   these recorded temperatures to the permanent log on a daily basis.  Any  magazine  with  a  temperature  consistently above 100ºF is reported to NAVSEASYSCOM. MAGAZINE SECURITY Unless work is actually being performed within the space,   all   ammunition   stowage   spaces   containing ammunition   or   explosives   are   secured   and   locked. Current directives and instructions require this action. Properly    securing    an    ammunition    stowage    space includes the following actions:   Properly set all environmental controls.   Close all hatches, doors, or accesses.   Properly set all dogs on watertight closures.   Lock the space with an adequate locking device. Some  ammunition  and  explosive  items,  such  as small arms ammunition, small arms, and pyrotechnics, are   highly   pilferable.   Stow   them   in   high-security stowage  spaces.  These  spaces  are  equipped  with  an unauthorized   entry   alarm   system   and   a   specially designed, high-security, locking device (fig. 11-8). The   ship's   gunner   maintains   and   controls   the magazine  keys,  including  the  high-security  keys.  The keys   are   logged   out   to   authorized   personnel   only. During  emergencies,  such  as  fire  and  flooding,  the ship's  gunner  provides  access,  as  necessary,  to  locked ammunition  spaces.  If  the  ship's  gunner  is  absent,  the weapons department duty officer performs this function. REVIEW NUMBER 2 Q1. Missile magazines are vented to _________. Q2. What item shouldn't be stowed in magazines that are equipped with sprinklers? Q3. In a shipboard magazine, what alarm circuit indicates a rapid rise in temperature? Q4. What  types  of  pallets  are  used  as  magazine stowage dunnage aboard ship? Q5. NAVAIRSYSCOM  should  be  notified  if  the temperature  in  any  magazine  is  consistently above ______. Q6. What   person   controls   all   magazine   keys aboard ship? AMMUNITION HANDLING LEARNING  OBJECTIVE:  Identify  ammuni- tion handling equipment used aboard ship and recognize   its   purpose   and   use.   Identify   the purpose and use of weapons elevators. 11-15 Figure 11-7.—Magazine Temperature Record Card.
