ENGINEMAN   1 &  C period  as  the  duty  office,  and  reports  to  that officer. and that the prescribed pressure is maintained in the firemain. Standing  Watches As a watchstander, you will be the “eyes” of the engineering department. You will be respon- sible for the orderly appearance and cleanliness of your assigned station. Prior to standing watch, you should thoroughly inspect all existing condi- tions,   such   as   the   operating   condition   of machinery   and   firefighting   equipment.   You should also check your assigned area for leaks and potential fire hazards. If a casualty occurs, you should take immediate steps to control it, as well as promptly notify the proper authority. Except  in  emergencies,  the  engineroom  aux- iliary  watch  does  not  make  any  changes  such  as stopping,   starting,   or   shifting   ship’s   service generators without first notifying the Electrician’s Mate and the petty officer in charge of the watch. A watch going off duty will not be considered relieved  until  the  floor  plates  are  wiped,  the engineroom is clean, all operating logs and records are correct, and information concerning the status of  the  machinery  in  operation,  orders,  special orders, and non-completed orders have been given to the relief. While on watch, you should strictly observe all   operating   instructions,   regulations,   and safety  precautions.  You  should  never  leave  your station unless you have permission from proper authority to do so, or are properly relieved. You should promptly execute all standing or special orders. When relieved, you should pass on to the relieving watch all information concerning existing conditions and special orders. There are several watches that you may stand or for which you may be responsible. The stations and  duties  of  some  of  the  watches  commonly stood by Enginemen are discussed in the follow- ing paragraphs. COLD-IRON  WATCHES.—Under  certain prescribed conditions (such as when a ship moves alongside a repair ship or tender, or into a naval shipyard,  and  is  receiving  power  from  these activities) a security and fire watch is usually set by each division. This security watch is commonly known as a cold-iron watch. Each cold-iron watch makes frequent inspections of the assigned area and checks for fire hazards, flooding, or other unusual conditions throughout the area. The cold- iron watch keeps bilges reasonably free of water in accordance with applicable instructions. Hourly reports on existing conditions are made to the officer of the deck. ENGINEROOM AUXILIARY WATCH.— Auxiliary  watches  are  maintained  underway  and in port to supply light, power, steam, and other services.  The  engineroom  auxiliary  watch  main- tained in port includes a petty officer in charge and one or more Firemen. The petty officer in charge  is  responsible  for  seeing  that  an  efficient and   economical   watch   is   being   stood.   All machinery not in operation must be checked to see that it has been properly secured. All  unusual  conditions  are  immediately reported  to  the  officer  of  the  deck  and  to  the engineering duty officer, so that the proper divi- sion or department can be notified to take the necessary corrective measures. When welding or burning is to be performed in the area, the cold- iron  watch  checks  to  see  that  a  fire  watch  is stationed. The petty officer in charge of the auxiliary watch is responsible for the proper operation of the   ship’s   service   generator   and   associated machinery; however, the operation of the elec- trical equipment is the responsibility of an Elec- trician’s Mate. The petty officer in charge checks to see that all operating machinery is lubricated as   prescribed   by   the   operating   instructions. He/she  makes  sure  that  the  fire  and  flushing pumps are inspected for satisfactory operation If the ship is in drydock, the watch must check all sea valves, after working hours, to see that the valves are secured or blanked off. The watch must make sure that oil or water is not being pumped into the drydock and that weights such as fuel oil, feedwater,   or   potable   water   are   not   shifted without permission of the engineer officer. DUTY ASSIGNMENTS As an Engineman, you will be assigned duty aboard various types of ships, ranging from air- craft carriers to the smallest of river patrol boats. You will also be assigned shore duty. Your specific 1-6
