FUEL HANDLING PRECAUTIONS. Table 2-2, Fuel Quantity Data, lists the quantity and capacity  of  fuel  tanks  in  the  aircraft.   Service  the  fuel tanks after each flight to keep moisture out of the tanks and   to   keep   the   bladder   type   cells   from   drying   out. Observe the following precautions: WARNING During warm weather open fuel caps slowly to prevent being sprayed with fuel. WARNING When  aviation  gasoline  is  used  in  a  turbine engine,   extreme   caution   should   be   used when  around  the  combustion  chamber  and exhaust area to avoid cuts or abrasions. The exhaust  deposits  contain  lead  oxide  which will cause lead poisoning. such  as  drills  or  buffers,  in  or  near  the  aircraft  during fueling. b. Keep  fuel  servicing  nozzles  free  of  snow,  water, and mud at all times. c. Carefully  remove  snow,  water,  and  ice  from  the aircraft fuel filler cap area before removing the fuel filler cap (fig. 2-30). Remove only one aircraft filler cap at any one  time,  and  replace  each  one  immediately  after  the servicing operation is completed. d.  Wipe   all   frost   from   fuel   filler   necks   before servicing. e.  Drain   water   from   fuel   tanks,   filter   cases,   and pumps  prior  to  first  flight  of  the  day.  Preheat,  when required,  to  insure  free  fuel  drainage. f.  Avoid  dragging  the  fueling  hose  where  it  can damage the soft, flexible surface of the deicer boots. CAUTION g. Observe NO SMOKING precautions. Proper  procedures  for  handling  JP-4  and JP-5   fuel   cannot   be   over   stressed.   Clean, fresh  fuel  shah  be  used  and  the  entrance  of water  into  the  fuel  storage  or  aircraft  fuel system must be kept to a minimum. CAUTION When conditions permit, the aircraft shall be positioned  so  that  the  wind  will  carry  the fuel vapors away from all possible sources of ignition. The fuel vehicle shall be positioned to  maintain  a minimum  distance  of  10  feet from  any  part  of  the  aircraft,  while maintaining  a minimum  distance  of  20  feet between the fueling vehicle and the fuel filler point. a.    Shut off unnecessary electrical equipment on the aircraft,   including   radar   and   radar   equipment.   The master  switch  may  be  left  on,  to  monitor  fuel  quantity gages,  but  shall  not  be  moved  during  the  fueling operation. Do not allow operation of any electrical tools, h.    Prior   to   transferring   the   fuel,   insure   that   the hose is grounded to the aircraft. i.    Wash off spilled fuel immediately j.  Handle  the  fuel  hose  and  nozzle  cautiously  to avoid damaging the wing skin. k.    Do not conduct fueling operations within 100 feet of energized airborne radar equipment or within 300 feet of  energized  ground  radar  equipment  installations. l.  Wear  only  nonsparking  shoes  near  aircraft  or fueling  equipment,  as  shoes  with  nailed  soles  or  metal heel plates can be a source of sparks.
