take control immediately. The following basic actions are normally part of the ECC center’s responsibilities: Establishing  immediate  communications  with all  assigned  stations. Ensuring  that  all  personnel  are  accounted  for and ready for battle. Maintaining  positive  communication  with applicable electronics spaces. This requires making a communication  check  (phone  check)  every  3  minutes  if no other traffic exists. Using a predetermined sequence of  answering,  the  phone  talker  calls  and  records  (checks off)  results.  The  ECC  supervisor  should  track  this procedure   closely   to   be   sure   communication   is maintained. After a hit (simulated or actual), running an immediate  phone  check.  After  the  phone  check,  all electronic  spaces  (manned  and  unmanned)  must  be checked thoroughly for damage. ECC will dispatch a minimum of two investigators to check known damaged spaces (including manned spaces that fail to respond to phone   check).   Unmanned   spaces   are   checked   by personnel in manned spaces, usually by a prearranged assignment.  Checks  of  unmanned  spaces  will  be  made only by, or as directed by, ECC. Maintaining  precise  monitoring  of  equipment, personnel,  and  casualties  on  a  status  board  using standard  damage-control  symbols. Dispatching  investigative  teams,  technical assistance,  and  parts  assistance  as  applicable.  All  teams must   use   preestablished   routes.   This   requires coordinating  with  damage  control  central  (DCC)  when the  opening  or  closing  of  damage-control  fittings  is involved. DCC should provide permission for ECC to investigate the main deck and above. Providing backup assistance as necessary by assigning personnel within the ECC organization or by coordinating other assistance, such as medical, damage control,  and  repair  teams,  through  damage  control central. Secondary ECC Personnel  assigned  to  the  secondary  ECC  are usually the assistant EMO or a senior CPO or petty officer,  a  status  board  plotter  and  phone  talker,  and  a casualty  investigation  team.  (If  manning  does  not provide  sufficient  personnel  to  have  teams  in  the secondary ECC, casualty investigation teams will be pulled  from  undamaged  spaces.) When  the  secondary  ECC  takes  control,  its responsibilities are the same as those of the primary ECC. The secondary ECC must maintain the precise status  of  equipment,  systems,  personnel,  and  casualties, matching the status indicated by the primary ECC. This means that the secondary ECC must closely monitor and record all status passed over the electronics casualty control  communication  circuits  and  the  ship’s announcing system MCs. PERSONNEL ASSIGNMENTS Suppose  an  extremely  bad  casualty  occurs  that “knocks out” the primary ECC and the secondary ECC. What  happens  in  this  situation?  Your  electronics casualty  control  organization  must  have  a  descending order  of  control  that  coincides  with  the  order  of reporting-in during phone checks or casualty hits. In any situation  involving  loss  of  both  the  primary  and secondary   ECC   centers,   casualty   control responsibilities pass to the next lower level in the ECC chain  of  command.  The  personnel  in  each  manned station of electronics casualty control should monitor and  record  all  status  passed  over  the  communications circuit to the best of their ability. You must carefully consider a variety of factors when you assign personnel to the various reamed battle stations.  You  must  take  into  account  each  person’s effectiveness, versatility, and other possible assets to have  the  most  suitable  and  efficient  electronics  casualty control organization. If you think carefully about these factors and make your assignments accordingly, the watch, quarter and station bills will contain the best combinations of personnel and duties. INVESTIGATIVE  TEAMS  AND ASSISTANCE Casualties  happen  during  both  actual  battles  and The  secondary  ECC  is  the  first  backup  to  the simulated  casualty  control  exercises.  This  means  that primary  ECC.  This  alternate  is  necessary  to  maintain casualties  to  electronic  equipment  or  systems,  spaces, casualty  control  if  the  primary  ECC  becomes  ineffective and personnel must be expected and that some means of because  of  personnel  casualties,  communication backup and casualty investigation must be assigned. For problems, flooding, tire, and such, that result from some example, a battle hit is taken, and a phone check yields type  of  battle  damage. one  or  more  spaces  not  answering;  therefore,  a  casualty 5-2
