Safety Precautions
Any fuelling operation can be very dangerous, and aviation fuel has a number of unique characteristics which must be accommodated. As an aircraft flies through the air, it can accumulate a charge of static electricity. If this is not dissipated before fuelling, an electric arc can occur, which may ignite fuel vapors. To prevent this, aircraft are electrically bonded to the fuelling apparatus before fuelling begins, and are not disconnected until fuelling is complete. Some regions require the aircraft and/or fuel truck to be grounded, as well.
Aviation fuel can cause severe environmental damage, and all fuelling vehicles must carry equipment to control fuel spills. In addition, fire extinguishers must be present at any fuelling operation, and airport firefighting forces are specially trained and equipped to handle aviation fuel fires and spills. Aviation fuel must be checked daily and before every flight for contaminants, such as water or dirt.
Many airlines now require safety belts be left unfastened should passengers be aboard when refuelling happens.'
