l   Probable   effects operator in proper systems’ alignment. An alignment diagram is used whenever two or  more  alignment  conditions  exist  for  a given  system  or  component. The operational use of EOP documentation is of primary importance at all levels in controlling, supervising,  and  operating  the  engineering  plant. ENGINEERING   OPERATIONAL CASUALTY   CONTROL The  EOCC  is  the  casualty  control  portion  of the EOSS. It contains information relevant to the recognition   of   casualty   symptoms   and   their probable   causes   and   effects.   Also,   it   has information  on  actions  taken  to  prevent  a casualty.  It  specifies  procedures  for  controlling single-  and  multiple-source  casualties. Casualty  prevention  must  be  the  concern  of everyone  on  board. Proper  training  of  all personnel  must  provide  an  adequate  knowledge and  experience  in  effective  casualty  prevention. The  EOCC  manual  has  efficient,  technically correct  casualty  control  and  prevention  pro- cedures. These procedures relate to all phases of an  engineering  plant.  The  EOCC  documents possible casualties that may be caused by human error,   material   failure,   or   battle.   The   EOCC manual describes proven methods for the control of  a  casualty.  It  also  provides  information  for prevention of further damage to the component, the system, or the engineering plant. The EOCC manuals (books) are available at each  watch  station  for  self-indoctrination.  The manuals contain documentation to assist engineer- ing personnel in developing skills in controlling casualties  to  the  ship’s  propulsion  plant. Skill  in  EOCC  procedures  is  maintained through  a  well-administered  training  program. Primary  training  concentrates  on  the  control  of single-source  casualties.  These  are  casualties  that may  be  attributed  to  the  failure  or  malfunction of a single component or the failure of piping at a  specific  point  in  a  system.  Advanced  training concentrates on controlling multiple casualties or on  conducting  a  battle  problem.  An  effective, well-administered  watch-stander  training  program will  contain,  as  a  minimum,  the  following elements: .  Recognition  of  the  symptoms l   Probable   causes .  Preventive  actions  that  may  be  taken  to reduce,  eliminate,  or  control  casualties An  EOSS  package  is  not  intended  to  be forgotten  once  it  is  developed  and  installed  aboard a  ship.  It  offers  many  advantages  to  the  ship’s operational  readiness  capabilities.  It  also  provides detailed step-by-step sequencing of events for all phases of the engineering plant operation. Because it is work studied and system oriented, the EOSS provides  the  basic  information  for  the  optimum use  of  equipment  and  systems.  It  does  this  by specifying   correct   procedures   tailored   for   a specific  plant  configuration. The  EOSS  is  not  intended  to  eliminate  the need  for  skilled  plant  operators.  No  program  or system  can  achieve  such  a  goal.  The  EOSS  is  a tool   for   better   use   of   personnel   and   skills available. Although the EOSS is an excellent tool for  shipboard  training  of  personnel,  it  is  primarily a working system for scheduling, controlling, and directing  plant  operations  and  casualty  control procedures. WATCH-STANDING   DUTIES AND RESPONSIBILITIES As a Fireman, you maybe assigned to one of many different types of ships. On these ships, the engineering spaces vary in size and appearance. On  a  steam-driven  ship,  the  boilers,  the  main engines, and their associated equipment may be in one space; or the boilers and their equipment may be in one space and the main engines and their  equipment  in  another.  Regardless  of  the number of boilers and main engines, the watches on most ships are basically the same. Therefore, this  information  is  general  in  nature  and  does  not apply  to  a  specific  class  of  ship. When  working  with  a  variety  of  propulsion, auxiliary,  and  electrical  equipment,  you  will  stand various  watches  that  range  from  main  switch- boards  to  security  watches  or  other  watches, depending  on  your  ship’s  organization.  When standing  these  watches,  you  will  be  required to  perform  many  tasks.  These  include  logging meter readings, inspecting equipment for leaks, and  preventing  fire  hazards.  This  section  has information on watches and duties that you may be  required  to  perform.  As  you  progress  and become better acquainted with the fireroom and engine  room,  you  will  stand  watches  under  the 1-18
