exists.  An  investigation  team  must  be  dispatched immediately  to  identify,  investigate,  and  correct  (if possible) the casualty. Assigned investigators should be trained to handle all casualties within a space either by repairing  the  casualty  themselves  or  by  requesting whatever  assistance  they  need. Assistance may be from either within or outside of the  ECC  organization.  Personnel  within  the  ECC organization will be dispatched by ECC as necessary. The ECC will request and coordinate external assistance through damage control central. ECC must ensure that damage control central is kept aware of arrivals and departures,  the  applicable  assistance  team  requested, and the status of the casualty. ELECTRONICS CASUALTY CONTROL MANUAL Effective electronics casualty control depends on the proper preparation and training of the personnel involved  in  both  operating  and  maintaining  the  ship’s equipment.  To  establish  an  effective  electronics  casualty control program, each ship must have a comprehensive ECC  manual.  The  following  paragraphs  describe  a typical ECC manual and its basic contents. Purpose of the Manual The casualty control manual (1) serves as a ready and rapid reference for technical details of the ship's electronics  system  installation  and  spaces  and  (2) provides data on available repair support material. For the manual to serve its purpose properly, you and your fellow senior personnel must ensure that all appropriate information concerning electronic systems, electrical power, spaces, distributions, damage control related items, and such, is documented in a format that will allow rapid retrieval of needed information. Damage  control  manuals  must  also  be  distributed properly if they are to contribute to effective casualty control. You should give careful thought to where the manuals  should  be  located.  They  should  be  quickly accessible  to  personnel  entering  any  space.  The  primary ECC, secondary ECC, and each space determined to be an ECC center alternate must have a complete (master) ECC manual that covers all spaces. All other electronics spaces  must  have  an  ECC  folder  containing  the  pages that pertain to that space and are identical to the master ECC  manual. Content of the Manual Most information in a casualty control manual is common knowledge to some of the personnel of your division;  so  collecting  this  information  will  not  require a great deal of research unless a major overhaul or alteration  to  equipments,  systems,  or  spaces  has occurred.   Often   when   “common   knowledge” information is critically required, those who have it are not available. Then someone must spend time locating data when the time should be spent on corrective action. Plan to prepare and update your casualty control manual during slack work periods, or task the duty sections to provide  inputs.  This  will  result  in  an  up-to-date, well-organized reference that will be a great asset to your ECC program. Figure 5-1 shows a typical table of contents of an ECC manual. The  ECC  folder  must  contain  the  following information: Fire-fighting  equipment  location First-aid  equipment  location Emergency  destruction  equipment  location Ventilation  controller  location Escape routes (on large ships) Electronics  emergency  access  routes Internal  communications Technical manual locations and indexes Power distribution diagrams Signal  distribution  diagrams Gyro signal distribution diagrams Equipment  air  system  diagrams Equipment  coding  system  diagrams Antenna  details Each  technician  (or  operator)  must  be  able  to  find any  item  in  the  folder  within  a  reasonable  time (approximately   2   minutes)   and   must   be   able   to physically locate anything listed in the folder for which he or she is responsible. TRAINING Electronics casualty control training is essential in the achievement of battle readiness. This training is usually   accomplished   through   casualty   control 5-3
