WARNING
Be sure that grounding connections are made properly and firmly before any fueling operations begin. This will ensure
that grounding connections will not release, thus climinating the possibility of sparks caused by static electricity which will
ignite the fuel. This applies to top loading and bottom loading at a fixed loading facility. Bottom loading is the preferred
method when facilities are available.
WARNING
Grounding cable must be connected before any servicing operations. The first clip should be attached to the ground rod.
The second clip should be attached to the aircraft grounding fitting, if one is provided, or to a convenient unpainted metal
point on the aircraft. Grounding should not be made to a propeller, radio antenna, or highly stressed components of the
landing gear where scratches could cause metal failure. Always disconnect the grounding clips in reverse order, first the
aircraft, then the ground rod. The grounding cables shall be disconnected only after fuel servicing operations have been
completed and all dispensing nozzles and hoses have been disconnected or removed from filler openings and stowed on
the refueling vehicle. Grounding cables attached to dispensing nozzles maybe disconnected only after nozzles have been
disconnected or removed from filler openings of aircraft being serviced.
WARNING
GROUND AIRCRAFT OR VEHICLE TO SEMITRAILER
Grounding of the semitrailer to aircraft or vehicle while refueling is mandatory, regardless of the amount of fuel to be
dispensed, due to the dangers of static electricity.
Bond the fuel nozzle to the aircraft before opening the filler cap. Connect closed circuit nozzles securely before
beginning fuel flow. Electrical hazards may be introduced in several ways, such as:
• Electrostatic sparks.
• Operating aircraft engines, auxiliary power units and heaters.
• Operating automotive or other internal combustion engines servicing equipment in the vicinity.
• Arcing of electrical circuits.
• Open flames.
• Energy from energized equipment.
• Lightning.
WARNING
Before performing maintenance on semitrailer, semitrailer must be grounded to an approved (earth) ground and it must
be safe to proceed. Failure to follow this warning may cause a spark to ignite, resulting in serious injury or death to
personnel.
WARNING
DO NOT let go of static reel cable when rewinding until ball stop is firmly touching the reel. Failure to follow this warning
may cause injury to personnel.
