The worker connects an earth wire to the aircraft before pumping fuel. Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. and charge can be transferred as the fuel flows through cause an Explosion? The ongoing Investigation has already established that the likely cause was fuel contamination resulting from the inadvertent mixing of a required fuel additive with an unapproved substance known to form deposits which impede fuel flow when they accumulate on critical fuel system components. There is a risk that a PED (personal electronic device) may create or induce a spark of sufficient intensity to ignite fuel vapour released during fuelling but it is extremely remote under normal circumstances. Disable or turn off any auxiliary sources of ignition such as a camper or trailer heater, cooking units, or pilot lights. Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. IBO was not involved in the production of, and does not endorse, the resources created by Save My Exams. You may apply lotion or moisturizer on your . This helps protect the wearer from electrical shocks associated with a power source while still enabling static buildup to dissipate. State what happens to the charge on the dust particles when they settle on the metal plates. Care must be taken to avoid sparks when putting fuel in What are the Dangers of Electrostatic Charge? Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. Why should there be any difference in reducing electrical FOD? Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. Our skilled professionals are on standby waiting to address your next electrical concern. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport.

The transfer of charge Passengers boarding or disembarking an aircraft other than via an airbridge should be discouraged from using PEDs. the charge was neutralised (1) by a transfer/flow of electrons. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. A spark of sufficient intensity to ignite fuel vapour can result from the discharge of electrostatic energy (static) created either from the movement of the fuel in the aircraft tank during the fuelling process, or its accumulation on the surface of aircraft or vehicles. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. Is static electricity dangerous in aircraft operation? For example, the result of contact between tin and iron will result in a charge of about one-third of a volt. 6 What are the dangers of using static electricity? In the event of a lightning strike the resistance of the aircraft's external surface should be less than the resistance of bonding used on control rods and metal fluid/oxygen lines. Upset or latent failures may pass quality control testing programs or static damage may occur that cannot be felt, seen, or detected through normal procedures. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. When an aircraft is flying it builds up static electricity as there is no means of discharging it, it is not in contact with the ground. Like other means of ESD protection their function should be verified and not taken for granted. the pipe. Turn off your vehicle engine. Use gasoline only in open areas that get plenty of fresh air. I received numerous replies so I thought I would add some additional information. The driver may be carrying excess electrons, which may create a spark when you touch the fuel pump.
