A. Safety Precautions

** On A/C 001-003(Ref. Fig. 12-11-28-991-00100-A - Refuel Safety Area)

(1) You must obey the Fuel Safety Procedures

** On A/C ALL

(Ref. TASK 28-00-00-910-001-A) when you refuel/defuel an aircraft.

(2) Do not let the tanker go near the aircraft until the anti-collision lights have been set to OFF.

(3) Before you start the refuel/defuel procedure, make sure that all the electrical circuits in the fuel systemare complete.

(4) Do not spill fuel on the engines or the brakes. If you spill fuel on engines or brakes that are hot, it cancause fires.

(5) Ground and bond the aircraft (Ref. TASK 12-34-24-869-001-B).

NOTE : Bonding is mandatory. For grounding you must obey the local area regulations.

(6) Move all the equipment and material which is not necessary for the refuel/defuel procedure out of thesafety area.

(7) On the panel 400VU, make sure that the ACCU PRESS on the triple indicator has sufficient pressure. Ifnecessary, pressurize the yellow hydraulic system (Ref. TASK 29-10-00-863-002-A).

(8) If the Main Landing Gear (MLG) doors are open during the refuel procedure:. visually examine the tires and shock absorbers. make sure you will have sufficient clearance to the ground after the refuel is complete.

(9) On the panel 110VU, make sure that the PARK BRK is ON.

NOTE : Airbus recommends that the park brake is set to ON when possible. You cannot set the PARKBRK to ON if you have hot brakes. If you cannot set the PARK BRK to ON, it is possible tocontinue but you must make sure the chocks are in the correct position.

(10) Make sure that the chocks are in position. The correct position for the chocks are:

(a) If the ramp is flat (no slope):. move the aft chocks away from the tires. During the refuel,the NLG tires will roll aft as the

MLG shock absorber compresses. make sure that the chocks do not touch the MLG tires. The weight of the fuel can lower the

aircraft and cause the chocks to be caught under the tires.

(b) If the ramp has a slope:. make sure that the chocks down from the tires touch the NLG and MLG tires. make sure that the chocks up from the tires do not touch the NLG and MLG tires.

NOTE : This makes sure that only chocks on one side of each tire will be caught so that it iseasier to release them.

(11) Make sure that there is no equipment below the aircraft which can cause damage. The weight of thefuel can suddenly compress the landing gear and lower the aircraft.

(12) Before you start the refuel/defuel procedure make sure that these are available:. a fuelling supervisor or fuelling safety person. the correct fire-fighting equipment. approved persons to use the fire-fighting equipment.

(13) Make sure that the overboard vent lines are not blocked. If they are blocked, damage to the fuel tankscan occur.

(14) Make sure that the fuel tanker (or hydrant) contains the correct fuel. The correct fuels are shown in theFlight Manual (Ref. FM 2.04.00).

(15) Make sure that the fuel tanker or the pump unit (if you use a hydrant to refuel the aircraft) is in thecorrect position.

(16) Make sure that, if there is an emergency, you can move the fuel tanker/pump unit and the otherequipment away quickly.

(17) Do not operate the aircraft main engines during a refuel/defuel procedure.

NOTE : In an emergency it is permitted to refuel with one engine running (Ref. FCOM 2.01.30).

(18) Auxiliary Power Unit (APU) starts or shutdowns are permitted during refuel/ defuel procedures. If it isnecessary to operate the APU, the limits that follow apply:

(a) An APU start is not permitted during a refuel/defuel procedure if the APU has failed to start oran automatic shutdown has occurred.

(b) You must complete a normal APU shutdown if a fuel spill has occurred during the refuel/defuelprocedure.

(19) Make sure that the electrical equipment you use will not cause a spark.

(20) Do not refuel/defuel in bad weather conditions and electrical storms. Lightning is dangerous.

(21) During the refuel/defuel procedure do not operate the aircraft external lighting.

(22) During the refuel/defuel procedure do not fill the oxygen system or change the oxygen bottles.

(23) During the refuel/defuel procedure do only essential aircraft maintenance and/or servicing that will notcause a spark.

(24) Do not refuel the aircraft if a fire or engine overheat warning is displayed on the flight deck.

(25) You are only permitted to replace or do small maintenance work on radio, radar and electricalequipment during refuelling.

(26) You are not permitted to remove, install or test aircraft batteries or related equipment during refuelling.

(27) Do not use the microphone on the High Frequency (HF) transmitter during refuel/defuel operations.

(28) Immediately flush away with water, or remove, fuel leakage.

(29) Obey the safety distances for 60 m (196.85 ft.) from aircraft:

(a) Stop the fuel tanker 60 m (196.85 ft.) from the aircraft nose while the weather radar operates. Donot operate the fuel tanker/pump unit until you stop operation of the weather radar.


(a) Aircraft must not be refueled/defueled less than 30 m (98.43 ft.) from the radar or HF radioequipment under test in the aircraft or ground installation.


(a) Put ”NO SMOKING” warning notices around the work area not less than 15 m (49.21 ft.) fromthe refuel/defuel equipment and aircraft and aircraft tank vents.

(b) Do not connect electrical equipment to a power source less than 15 m (49.21 ft.) away, unless thepower source has spark-proof connectors.

(c) Refuelling/defuelling equipment and aircraft fuel-tank vents must not be nearer than 15 m (49.21ft.) to a building during refuelling/defuelling. Make sure the position of the refuelling/defuellingarea cannot let this occur. Because of the design of some buildings, you can dorefuelling/defuelling operations nearer than 15 m (49.21 ft.). Examples of this type of building arenose loaders and aerobridges.


** On A/C 001-003(Ref. Fig. 12-11-28-991-00100-A - Refuel Safety Area)

(a) Ground power units (GPU’s) can be operated when they are put not less than 6 m (19.68 ft.)from:. the aircraft filling and venting points. the hydrant valves and other refuel/defuel equipment when in use.

(b) Photographic flash bulbs or electronic flash equipment must not be used less than 6 m (19.68 ft.)from:. the refuel/defuel equipment. any filling or venting points of the aircraft.

(c) The refuel/defuel zone must be regarded as extending not less than 6 m (19.68 ft.) radially from:. the filling and venting points on the aircraft. the refuel/defuel equipment. the hydrant valve in use for refueling (when applicable).

When defueling is taking place, the vehicle will be venting and will generate a zone radiating fromthe tank vent.

(d) Do not operate the items that follow inside the 6 m (19.68 ft.) zone:. radios. radio telephones (cell phones or mobile phones). pagers. switches on lighting systems of other than intrinsically safe types.

(e) Personnel in the refuel/defuel zone and those employed in refueling/defueling must not:. carry matches or other means of ignition. put on foot-wear with exposed iron or steel studs, nails or tips.
