TASK 12-34-24-869-001-A	Aircraft Bonding and Grounding (Earthing) for the Refuel/Defuel or Oxygen Servicing Operations

A. Not Applicable

A. Safety Procedures
(1) Make sure that the aircraft is grounded correctly (Ref. AMM TASK 12-34-24-869-001).
(2) Make sure that there is sufficient light in the work area to work safely.
(3) Use only the recommended safe test equipment for maintenance procedures.
(4) Use only the approved LIGHT SOURCE - SPARK-PROOF and FLASHLIGHT in the fuel tank. Sealed vapour lamps must not be used.
(5) Make sure that the flow of clean air in the work area is sufficient to work safely.
(6) Before you start the maintenance task make sure that these are available:

the correct fire-fighting equipment
approved persons to use the fire-fighting equipment.

(7) Be careful when you disconnect fuel pipes and/or remove components from the fuel system. There can be some remaining fuel in the system.
(8) Do not get aircraft fuel in your eyes, mouth, nose, ears or on your skin.
(a) If you get aircraft fuel in your eyes, mouth, nose or ears:
1 Flush with clean water.
2 Get medical aid.
(b) If you get aircraft fuel on your skin:
1 Remove all clothing soaked with fuel.
2 Clean the skin with soap and water.
3 Flush the skin with clean water.
4 If the skin is dry, apply an approved cream to it.
(9) Do not get your clothes soaked with fuel.
(10) Use approved protective clothing made from material that:

will not cause sparks
is applicable to your local regulations.

(11) Protect your skin with barrier cream.
(12) You must use a respirator if the fuel-gas concentration in the work area is more than 5% of the lower explosive limit (LEL).
(13) Put WARNING NOTICE - NO SMOKING around the work area.
(14) In the work area you must not:

smoke
use flames which do not have protection
operate electrical equipment that is not necessary for the task
pull or move metal objects along the ground
use footwear which has metal studs or bare steel toe-caps
use hearing-aids or battery-operated equipment which will cause sparks
have material which will cause sparks or flames.

(15) You must immediately flush away or remove all fuel leakage.
(16) You must put all material which is used to remove fuel leakage in special fire-proof containers.
(17) You must do all maintenance tasks in very clean conditions.

WARNING: DO NOT USE METAL WIRE WOOL IN FUEL TANKS. THE METAL WIRE WOOL STRANDS CAN CAUSE ELECTRICAL ARCING, WHICH CAN START A FIRE.

(18) You must not use metallic wire wool in a fuel tank.
(19) Use only approved cleaning materials.
(20) Make sure that all signs of solvents and cleaning agents are removed from the equipment/components before they are installed.
(21) Make sure that all electrical circuits in maintenance are isolated before you apply electrical power to the aircraft.
(22) Put CAP - BLANKING on all disconnected pipes and openings in components and tanks.
(23) If possible, safety all components before you put them inside the fuel tank.
(24) Make sure that all the fuel system components have correct electrical bonding.
(25) Do not connect electrical equipment to a power source less than 30 meters away, unless the power source has spark-proof connectors.

A. Safety Procedures

WARNING: YOU MUST WEAR SAFETY BREATHING EQUIPMENT WHEN YOU DO WORK IN A FUEL TANK. THE TANKS CAN CONTAIN AIR FROM THE TANK INERTING SYSTEM. AIR FROM THIS SYSTEM HAS A LOW-OXYGEN CONTENT AND CAN CAUSE INJURY AND DEATH.

(1) Make sure that the aircraft is grounded correctly (Ref. AMM TASK 12-34-24-869-001).
(2) Make sure that there is sufficient light in the work area to work safely.
