SAFETY PRECAUTIONS LEARNING  OBJECTIVE:  Recognize  safety precautions   to   follow   when   handling   sus- pension, arming, and releasing equipment. As an AO, you need to be concerned with safety when working with suspension, arming, and releasing systems.  It  is  doubtful  there  is  a  petty  officer  in  the Navy  who  has  not  witnessed  a  minor  mishap  with suspension, arming, and releasing equipment. Accidents can be prevented if safety precautions and maintenance instructions are followed. Accidents can be prevented if personnel are trained and educated to work on the equipment. As a petty officer, it is part of your job to follow safety precautions and maintenance instructions  and  train  new  personnel.  A  few  safety precautions  that  you  need  to  follow,  and  train  your subordinates to follow, are shown below. ·  Keep  all  components  of  the  various  systems clean, well adjusted, and lubricated as prescribed. ·  Make operational checks or periodic inspections of  the  system  under  the  direct  supervision  of fully qualified personnel. ·  Never  insert  your  fingers  or  tools  into  a  rack when the rack is cocked. ·  Check  wiring  and  electrical  fittings  regularly. Replace  frayed  or  broken  wiring.  Check  plugs for condition and proper installation. ·  Never bypass safety circuits or devices or make them inoperative. ·  Don't   use    any    safety    pin    other    than    the prescribed one. ·  When  stores  are  loaded,  install  safety  pins  or other   safety   devices   as   prescribed   while   the aircraft is on the ground. ·  Never install  or  arm  an  ejector  rack  unless  the safety pin(s) and flag(s) are in place. ·  Don't  use   an   ohmmeter   to   check   electrical continuity of an electrically primed cartridge. ·  Remove or electrically disconnect all cartridges from the rack firing circuits before removing any component. ·  Install  only  the  prescribed  cartridges  in  ejector devices. ·  Never allow a dual breech ejector unit to be fired without   two   cartridges   or   a   cartridge   and authorized filler plug in the breeches. ·  Never allow an ejector unit to be fired without a store latched in place. ·  When  loading  stores,  inspect  all  handling  gear carefully. Don't use doubtful gear. ·  When loading stores, make sure that the store is in position and the rack is securely locked before removing hoists. ·  Don't place any part of your body under stores being  loaded  or  unloaded  if  it  is  possible  to accomplish the job without doing so. ·  When  installing  suspension  equipment,  torque all installation bolts or screws to the prescribed torque value. ·  Make sure quality assurance personnel familiar with the system inspect all final work performed on   the   armament   system.   Operational   tests should   be   made   on   repaired   systems   where necessary.
