TM 1-1500-204-23-9 (4) Storage shall not be on floors below grade and first tier of containers shall be laid at least 2 inches above  floor  level  to  provide  for  suitable  ventilation  and drainage.  Sills shall be provided at openings to storage areas, approximately 6 inches above floor. (5) Paint components and thinners packaged in    55    gallon    steel    drums    may    be    stored    outdoors provided   containers   are   protected   against   rusting   by painting of bare metal areas and are set on dunnage so as   to   provide   approximately   2   inch   clearance   above ground.  Drums stored out of doors shall be laid on their sides to protect loss of markings stencilled on the heads through weathering action of rain, snow, and sun. (6) Handling of stock shall be conducted in a manner to avoid damage to labels.  Relabeling of drums where    labels    have    been    obliterated    may    result    in mislabeling,  with  consequent  incorrect  use  of  waste  of contents.      Drums   with   obliterated   labels   should   be properly discarded. (7) Care should be taken to assure protection of  the  paint  or  components  from  moisture.    Particular care   should   be   exercised   to   prevent   water   entering containers as paint is opened. (8) Containers     of     paint     shall     be     readily accessible   at   all   times.      Other   supplies   shall   not   be stacked on top of paint. (9) Containers  shall  be  stored  and  issued  in order   of   dates   of   manufacture   shown   on   respective labels.    Containers  bearing  oldest  date  shall  be  used first.  In the event that date of manufacture is not shown on   container,   date   of   receipt   shall   be   considered   as approximate date of manufacture for purpose of storage and issue. (10) To give best results, temperature of paint should be between 60 and 85 °F (18 and 29°C)at time of use.  Storage conditions that result in paint temperatures below 55°F (13°C) or above 95°F (350C) require storage of paint at room temperature for approximately 25 hours prior to use. (11) In    closed    containers,    temperature    and humidity will not affect the stability of either component of two part coatings.  Although the paint manufacturers only   guarantee   two   part   coatings   for   one   year,   both components will remain stable for 2 to 3 years, as long as  the  component  B,  the  catalyst  portion,  remains  in closed and sealed containers.  Where it is necessary to extract a portion of the component B, it should be done in a cool location and the lid resealed as rapidly and as tightly, as possible. 9-4.    Reflectorlzing  and  Checkered  Flags.    Ground support  equipment  and  vehicles  used  on  the  flightline and  other  areas  where  aircraft  may  be  must  be  highly visible   for   safety.      The   following   paragraphs   outline reflectorizing    or    flag    requirements    and    installation location and procedures. CAUTION To    insure    high    visibility    during    flight line/airfield  operations,  all  aircraft  ground support  equipment  (vehicle  or  pieces  of equipment    used    to    direct    support    of aircraft/airfield  operations)  will  be  striped with   reflectorized   tape   or   will   display   a white-orange checkered flag. a. Reflectorized Tape Use.  All  non-tactical ground support  equipment  (which  is  normally  painted  yellow) will   be   outlined   with   reflective   tape   to   insure   high visibility  during  lowlight  level  operations.    Striping  shall be    in    accordance    with    materials    and    instructions specified in paragraphs b and c. b. Reflectorized  Tape  Location.    Equipment  shall be  marked  in  a  manner  to  outline  the  entire  piece  of equipment,  so  that  during  periods  of  low  visibility  the entire outline of the equipment will be obvious.  Outline the equipment as follows: NOTE If area to be striped can not accommodate  4  inch  wide  tape,  use  the widest width possible. (1) Outline  the  equipment  with  4  inch  wide silverwhite  tape  conforming  to  Federal  Specification  L- S-300, NSN 9390-00-949-8047. (2) Compound  surfaces  (corners,  large  bolts, rivets, etc.  ) may be left unmarked. c. Reflectorized  Tape  Installation.      The   following procedures     shall     be     used     to     apply     reflectorizing sheeting, Federal Specification L-S-300: (1) Clean  surfaces  of  all  loose  scale  and  dirt by   brushing   or   applying   cleaning   compound,   Federal Specification P-C-437.  Remove deposits of cleaning 9-16
