TM 1-1500-204-23-4 CHAPTER 2 ELECTRIC SHOP OPERATIONS 2-1.        General    Shop    Rules.        The    practices    and procedures described in this chapter pertain to the repair functions  of  aviation  activities  and  are  applicable  to  all levels  of  maintenance.    Because  of  the  many  types  of Army  aircraft,  each  shop  within  the  manufacturing  and repair section must, of necessity, have personnel trained in  general  practices  and  procedures  to  the  extent  that different type and model aircraft do not upset a smooth running shop. a. Responsibility.  All supervisory personnel in the manufacturing  section  are  responsible  for  a  continuing and  effective  shop  safety  program.    To  implement  and maintain   this   program,   shop   supervisors   will   utilize bulletin  boards,  signs,  and  any  other  effective  method. Shop    personnel    will    cooperate    in    the    shop    safety program    by    making    helpful    recommendations,    and continually exercising care and caution in the operation of all shop equipment.  All shop personnel will strive to improve  the  safety  program  and  be  especially  alert  to observe    and    correct    unsafe    shop    practices.        All accidents, no matter how minor, shall be reported to the shop supervisor, and all published instructions regarding safety    shall    be    strictly    adhered    to.        Also,    safety engineers   and   safety   officers   will   ensure   that   proper safety procedures are adhered to in accordance with AR 385-10, Army Safety Program; AR 385-30, Safety Color Code    Markings    and    Signs;    AR    385-32,    Protective Clothing  and  Equipment;  TB  385-4,  Safety  Precautions for Maintenance of Electrical/Electronic Equipment; The Occupational   Safety   and   Health   Act   of   1971,   OSHA 1910.    251;  all  applicable  fire  codes,  NFPA  410;  and other accepted civilian and military safety practices. b. Shop    Housekeeping.        Housekeeping    is    the yardstick   by   which   the   shops   in   the   manufacturing section  are  judged.    A  dean,  well-arranged  shop  is  a safe shop and reflects credit on all personnel concerned with its operation.  The following shop practices shall be observed: (1) Oil pans or drip pans shall be used where leaking   oil,   grease,   and   similar   materials   may   cause hazardous  accumulations  on  equipment  or  floors.    All spills   shall   be   cleaned   up   immediately.      Approved sweeping   compound   may   be   used   to   remove   these materials from the floor. CAUTION Floors  shall  not  be  cleaned  with volatile  or  flammable  liquids.    A flammable   film   may   remain   and cause a fire hazard. (2) Floors   shall   be   maintained   smooth   and clean,  free  of  all  obstructions  and  slippery  substances. Holes   and   irregularities   in   floors   shall   be   repaired   to maintain a level surface free from tripping hazards. (3) All  unnecessary  materials  on  walls  shall be removed and projections shall be kept to a minimum. (4) Aisles   shall   be   dearly   defined   and   kept free  of  hazardous  obstructions.    Where  possible,  aisles shall be suitably marked by painting. (5) All machines, work benches, aisles, etc.  , shall be adequately illuminated. c. Equipment  Safety  Unsafe   equipment   shall   be reported  immediately.    The  following  equipment  safety practices shall be observed: (1) Machines    shall    be    located    to    provide operators  with  sufficient  space  to  handle  materials  and perform job operations without interference. (2) Substantial     low     resistance     conductors shall   be   used   to   ground   all   stationary   and   portable machines,   equipment,   or   other   devices   where   static charges  may  be  generated,  or  which  require  electrical circuits of a hazardous nature. (3) Shop machinery shall be operated only by qualified personnel observing safe practices. (4) Safety devices, such as guards, interlocks,  automatic  releases,  and  stops,  shall  always be kept in operating condition. (5) Ensure   that   all   unauthorized   personnel are  clear  of  area  before  opening  valves  or  energizing electrical circuits for starting machinery. Change 3 2-1
