or leaving port, or refueling or replenishing from another  ship.  Since  the  sound-powered  telephones provide  communications  between  all  the  engineer- ing  spaces,  you  must  know  the  proper  procedures. When  you  talk,  speak  slowly  and  distinctly. Pronounce  the  syllables  of  each  word  very  clearly. When  you  receive  a  message,  or  are  given  a message  to  transmit,  repeat  it  word  for  word, exactly as it was given to you. Do not engage in any idle chatter. As the messenger of the watch, you will also perform  other  duties  as  assigned  by  the  petty officer  of  the  watch.  These  duties  include checking  operating  machinery  and  recording temperature  and  pressure  readings  in  the appropriate  logs. The  operating  log  is  an  hourly  record  of operating pressures and temperatures of almost all  operating  machinery.  The  log  readings  include lube  oil  and  boiler  pressures  and  temperatures, pump suction and discharge pressures, and other items  needed  to  operate  the  engineering  plant. You will have to write and print legibly. You also have to spell common Navy terms correctly and maintain  your  logs  neatly  and  accurately.  You should  know  the  proper  operating  and  limiting or  danger  pressures  and  temperatures  of  your equipment. This allows you to know when a piece of  machinery  or  equipment  is  not  operating properly. COLD-IRON   WATCH When a ship stops operating its own plant and is  receiving  services  from  shore  or  other  ships,  the ship is considered to be in a cold iron status. A security  and  fire  watch  is  usually  set  by  each department.  This  watch  is  called  the  cold-iron watch. Each cold-iron watch makes frequent inspec- tions  of  the  assigned  area  and  looks  for  fire hazards,  flooding,  or  other  unusual  conditions throughout  the  area.  The  watch  sees  that  no unauthorized persons are in the watch area; that all  spaces  are  cleaned;  and  that  no  tools,  rags, gear, and the like are left adrift. The watch also keeps the bilges reasonably free of water.  (NOTE: You must get permission to pump water from the duty  engineer  officer  and  the  OOD.) The watch makes hourly reports to the OOD or  the  DCC  watch  on  all  existing  conditions. Any  unusual  conditions  are  reported  to  the OOD  or  DCC  immediately.  They  can  notify  the department  responsible  to  take  the  necessary corrective  measures. When hot work is done in the watch area, the cold-iron   watch   ensures   that   a   fire   watch   is stationed.  The  fire  watch  stands  by  with  a  C0₂ extinguisher. If  a  fire  watch  has  not  been stationed,  the  cold-iron  watch  stops  all  work until a fire watch can be stationed. The cold-iron watch then carries out all pertinent orders. If  the  ship  is  in  dry  dock,  the  cold-iron watch  will  check  all  sea  valves  after  working hours. This is to ensure that the valves are secure or blanked off. The cold-iron watch also ensures that no oil is pumped into the dry docks at any time. The watch will not allow any weights, such as  fuel  oil  or  feedwater,  to  be  shifted  without permission  of  the  engineer  officer  or  DCA. BURNERMAN The   burnerman   is   responsible   for   cutting burners  “in”  and  “out”  as  directed  by  the  boiler technician of the watch (BTOW). The burnerman must keep a close check for dirty atomizers and change them when authorized by the BTOW. The burnerman  must  always  be  assisted  by  another watch  stander  when  lighting  fires  or  cutting  in additional burners. This procedure will ensure that fires are safely lit and are burning properly, that no fuel leaks, and that fires can be quickly secured if  a  casualty  occurs. CHECKMAN/UPPER-LEVEL  WATCH On ships that do not have automatic feedwater controls,   the   checkman   is   responsible   for operating the feed check valve and maintaining the  proper  water  level  in  the  steam  drum.  This is  the  checkman’s  only  responsibility.  On  ships that  have  automatic  feedwater  controls,  a checkman  is  not  needed  unless  the  control  is shifted  from  automatic  to  manual.  The  respon- sibilities of the upper-level watch include (1) the operation of the forced draft blowers, deaerating feed  tank,  and  all  boiler-related  equipment  on  the upper level; (2) surface blowing; (3) starting and stopping   machinery;   (4)   opening   and   closing valves;  (5)  monitoring  gauges;  and  (6)  aligning systems. FIREROOM  LOWER-LEVEL The  fireroom  watch  is  responsible  for  starting, stopping,   and   maintaining   proper   levels   and pressures on all boiler-related equipment on the lower  level.  This  equipment  will  normally  include the  main  feed  booster  pumps  and  the  fuel  oil 1-20
