TM 1-1500-204-23-9 NOTE Paint exhaust manifold only during overhaul  or  when  processing  equipment for storage. (3)    Battery  compartments.    Battery  compartments should   be   neutralized,   surface   stripped,   and   cleaned prior to painting. (a)    Neutralization  of  acid  electrolyte.    Exercise care  to  prevent  acid  from  spreading  to  adjacent  areas. Wash  areas  affected  by  battery  acid  with  20  percent solution of sodium bicarbonate, Federal Specification O- S-576,   in   water.      Neutralization   is   completed   when bubbling ceases.  After neutralization, remove all traces of sodium bicarbonate solution with generous quantities of water to prevent corrosion. (b)  Neutralization of alkaline electrolyte.  Exercise caution   to   prevent   acid   from   spreading   to   adjacent areas.      Wash   areas   affected   by   electrolyte   with   3 percent solution of boric acid in water.  Neutralization is completed  when  bubbling  ceases.    After  neutralization, remove all traces of boric acid with generous quantities of water. (c)  Treatment after neutralization.  Treat affected area  by  swabbing  with  5  percent  solution  of  chromic acid,   Federal   Specification   O-C-303,   or   5   percent   of potassium  dichromate,  Federal  Specification  O-P-559. Follow   by   flushing   with   water,   thorough   drying   and mechanical   stripping   of   any   areas   that   may   require stripping.  Thoroughly clean and dry the affected area in accordance with TM 55-1500-333-24. (d)    Painting.    After  neutralization,  stripping  and cleaning, apply the following paint system: 1    Apply  two  coats  of  epoxy  polyamide  primer, MIL-P-23377, type 1 or MIL-P-85582. 2    Apply  over  these  coats  one  coat  of  primer coating epoxy, MIL-P-52192. NOTE MIL-P-23377   is   yellow,   MIL-P-85582   is green   and   MIL-P-52192   is   red.      When wear,     scratching     or     topcoat     damage occurs,    yellow,    green,    or    red    primer undercoats   will   expose,   indicating   that repainting is necessary.  This is essential to protect the substrate structures. 3  Apply a topcoat of Lacquer, Acid Resistant for Aluminum,  Federal  Specification  TT-L-54,  or  Varnish, Asphalt,  Federal  Specification  TT-V-51,  for  other  than aluminum substrates. WARNING · Military Specification MIL-R-81294 may be used on aluminum or magnesium substrates.  MIL-R-81294 remover contains highly volatile methylene  chloride  as  a  constituent. Its  vapors  are  hazardous  to  breathe and/or will cause skin burns. Although   methylene   chloride   is   not flammable,    other    constituents    are. When the blanketing effect of methylene  chloride  is  lost  through  its volatility,   the   remaining   constituents may, under certain conditions, become ignitable. · Any  paint  remover  on  the  skin  or  in the eyes must be flushed immediately and thoroughly with water. In addition, medical treatment should be sought     promptly     in     the     case     of contact with eyes. · Protective    clothing    and    equipment such as rubber gloves, aprons, boots, approved     organic     vapor     cartridge respirators (TB MED 223 and supplement   to   Table   11,   TB   MED 223),    appropriate    eye    shields    and goggles shall be used as necessary to provide adequate protection for personnel. · The    painting    operation    should    be reviewed   by   the   installation   safety office     and     MEDDAC     Health     and Environment Activity to determine the presence  of  any  operational  hazards and   to   make   recommendations   for either  eliminating  or  controlling  those hazards found. c.      Cleaning   and   Stripping   of   Surfaces.      The   only chemical  paint  remover  authorized  for  use  on  ground support   equipment   surfaces   is   MIL-R-81294.      Other chemical removers cannot be used unless authorized by AMSAV-EIG. 9-5
