,, OPERATIONS 407-15
the operator shall touch the filler cap with the nozzle spout before removing the cap in order to equalize the potential between the nozzle and the filler port. The spout shall be kept in contact with the filler neck until the fueling is completed. 5.4.3* Where a funnel is used in aircraft fueling, it shall be kept in contactwith the filler neck as well 

### as the fueling nozzle spout or the supply container to avoid the possibility ofa spark at the fill opening. Only metal funnels shall be used. 5.4.4 Where a hydrant servicer or cart is used for fueling, the hydrant coupler shall be connected to the hydrant system prior to bonding the fuel equipment to the aircraft. 5.4.5 Bonding and fueling connections shall be disconnected in the reverse order ofconnection. 5.4.6 Conductive hose shall be used to prevent electrostatic discharge but shall not be used to accomplish required bonding. 5.5 Operation ofAircraft Engines and Heaters. 5.5.1 Fuel se-rVicing shall not be performed on a fixed wing aircraft while an onboard engine is operating. (See 

### Section .5.21.) Exc1Jtion: In an emergenc-y nsulting from thefailun ofan onboard auxiliary power unit on ajet aircraft and in the absence ofsuitable ground support equipment, ajet engine mounted at the rear ofthe aircraft or on the wing on the side opposite thefueling point shall be permitted to be operated during fueling to

### providepower, provided that th.e operationfollows writtenprocedures approved 

### by the authority havingjurisdiction. 5.5.2 Combustion heaters on aircraft (e.g

., wing and tail surface heaters, integral cabin heaters) shall not be operated during fueling operations. 5.6 Internal Combustion Engine Equipment Around Aircraft (Other than Aircraft Fuel Servicing Vehicles)

. 5.6.1 Equipment, other than that performing aircraft servicing functions, shall not be permitted within 15 m (50 ft) of aircraft during fuel servicing operations. 5.6.2 Equipment performing aircraft servicing functions shall not be positioned within a 3 m (10 ft) radius of aircraft fuel system vent openings

. 5.6.3 During overwing aircraft fuel servicing where aircraft fuel system vents are located on the upper wing surface, equipment shall not be positioned under the trailing edge of the wing

. 5

.7• Electrical Equipment Used on Aircraft Servicing Ramps. 5

.7.1 Battery chargers shall not be connected, operated, or disconnected while fuel servicing is performed on the aircraft. 5.7. 2• Aircraft ground-power generators or other electrical ground-power supplies shall not be connected or disconnected while fuel servicing is performed on the aircraft. 5.7.3 Electric tools or similar tools likely to produce sparks or arcs shall not be used while fuel servicing is performed on the aircraft. 5.7.4 Photographic equipment shall not be used within 3m (10 ft) of the fueling equipment or the fill or vent points of aircraft fuel systems

. 5.7.5 Other than aircraft fuel servicing vehicles, batterypowered vehicles that do not comply with the provisions of this standard shall not be operated within 3 m (I0 ft) of fueling equipment or spills. 

### (See Section .5. 6.) 5.7.6* Communication equipment located outside of the cab of the vehicle and used during aircraft fuel servicing operations within 3m (10ft) ofthe fill or vent points ofaircraft fuel systems shall be listed as intrinsically safe for Class I, Division I, Group D hazardous (classified) locations in accordance w ith ANSI/UL 913. 5.8 Open Flames on Aircraft Fuel Servicing Ramps. 5.8.1 Entrances to fueling areas shall be posted 11fith "no smoking" signs. 5.8.2 Open flames on aircraft fuel servicing ramps or aprons within 15 m (50 ft) of any aircraft fuel servicing operation or fueling equipment shall be prohibited. 5.8.3 The category of open flames and lighted open-f1ame devices shall include, but shall not be limited to , the foll owing : (1) Lighted cigarettes, cigars, pipes (2) Exposed flame heaters, liquid, solid, or gaseous devices , including portable and wheeled gasoline or kerosene heaters (3) Heat-producing, welding, or cutting devices and blow

torches (4) Flare pots or other open-flame lights 5.8.4 The authority having jurisdiction can establish other locations where open flames and open-flame devices shall not be permitted. 5.8.5 Personnel shall not carry lighters or matches on their person while engaged in fuel servicing operations

. 5.8.6 Lighters or matches shall not be permitted on or in fueling equipment. 5.9* Lightning Precautions. 5.9.1 Fuel servicing operations shall be suspended where lightning flashes are in the immediate vicinity of the airport

. 5.9.2 Awritten procedure shall be established to set the criteria for where fueling operations are to be suspended at each airport as approved by the fueling agent and the airport authority. 5.10 Aircraft Fuel Servicing Locations. 5.10.1 Aircraft fuel servicing shall be performed outdoors. Aircraft fuel servicing incidental to aircraft fuel system maintenance operations shall comply with the requirements of NFPA410. 5.10.2* Aircraft being fueled shall be positioned so that aircraft fuel system vents or fuel tank openings are not closer than 7.6 m (25 ft) to any terminal building, hangar, service building, or enclosed passenger concourse other than a load

ing walkway. Aircraft being fueled shall not be positioned so that the vent or tank openings are within 15 m (50ft) of any combustion and ventilation air-intake to any boiler, heater, or incinerator room. 5.10.3 Accessibility to aircraft by emergency fire equipment shall be established for aircraft fuel servicing positions

. 5.11 Aircraft Occupancy During Fuel Servicing Operations

. 5.11.1 If passengers remain onboard an aircraft during fuel servicing, at least one qualified person trained in emergency evacuation procedures shall be in the aircraft at or near a door
