Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. As the nozzle (the end) of the pipe is Czech Airlines Airbus A310 being fueled in Prague - Source: Kristoferb, 2010 (Wikicommons), Human Error in Aviation and Legal Process, Stabilised Approach Awareness Toolkit for ATC, Flight Deck Procedures (A Guide for Controllers), C550, en-route, north of Savannah GA USA, 2019, B772, en-route, northern Indian Ocean, 2014, ICAO Doc 9977, Manual on Civil Aviation Jet Fuel Supply, IR-OPS paragraph CAT.OP.MPA.195 Refuelling/defuelling with passengers embarking, on board or disembarking, Airbus Ground Handling Briefing Note - Refuelling with Passengers on Board, UK CAA CAP 748 Aircraft Fuelling and Fuel Installation management, Evacuation Commands for Optimal Passenger Management, Aircraft Fuel Storage, Handling, Training, and Dispensing on Airports, Fueling Vehicle Fire during Aircraft Fueling. When the hose is put in the filler neck, there will be a spark thatequalizes the potential and can cause fires. 3 Is static electricity dangerous in aircraft operation? 0000058115 00000 n Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize If the charge is very large, a spark to the earth may happen unexpectedly. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. Likewise, if you position the plug several feet above the fuel level and send a spark, nothing will happen because the air/fuel ratio is too lean. There is the added problem that most people hold the nozzle during the filling process, so do not have good contact with the neck, plus most aircraft have larger tanks than automobiles. Static Electricity Can Cause Fires! igniting Some locations have a strong reason for eliminating these little charges. The surfaces will repel each other, when they have the same charge. 0000005874 00000 n A person could die from an electric shock. Static electricity in the wrong environments, however, may be dangerous. The Investigation found that a system fault had caused overfuelling and that the manual check carried out to confirm the actual fuel load had failed to detect it because it had been not been performed correctly. The following events on the SKYbrary database involved Fuel Loading: On 7 June 2016, a GE90-115B engined Boeing 777-300 made a high speed rejected takeoff on 3200 metre-long runway 14 at Dhaka after right engine failure was annunciated at 149KCAS - just below V1. A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. this can cause an explosion. In a scientific perspective, static happens when theres an imbalance of charges between two objects. The issues are much the same whether the fuel source is a tanker/bowser or a fuel hydrant system. Links How do we deal with this invisible and silent foe? Like other means of ESD protection their function should be verified and not taken for granted. Privacy Policy. The fuel itself is an insulator (a hydrocarbon) that will greatly reduce the possibility of ESD. 0000005853 00000 n Foreign Object Damage (FOD) is something that has been drilled into the minds of aviation personnel. The aircraft is also connected by a metal cable to the refuelling tanker. *R X P0#NtoC 0h!a%%1^K rV"3\$3LvgNP D$PF0$Hv 9$56ef>mD=qu@%xNo5osEQC:#;RFVL};KZ7r9]#9sGkk^5=B,x%vx^c\byr#~cWY%{ 8 When to ground a fire truck for static electricity? | Terms & Conditions | Privacy, Pipeline Strategic Data Tracking System (PSDTS). Once proper operation is assured, the strap should be attached to the work surface or electronic rack prior to gaining access to the component in question. A sufficient quantity of fuel vapour to create a high risk of ignition may result from spillage arising from procedural errors, leaks, aircraft tank venting or failure of pressurized fuel lines or their couplings. WJhE7,> mo9?]RC"iGJ$iZt)6fVCPN|B{`m'i! We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. and any charge can be safely Name the kinds of evidence that systematists use in constructing a phylogenetic tree. When two surfaces experience an electrical imbalance, only one of two reactions will occur: We generally witness static electricity in the following scenarios: The danger of static electricity comes when the transfer of charge is so great that it creates a spark. Containers should never be filled while inside a vehicle or its trunk, the Relative humidity of the air along with atmospheric contaminates will have an effect on the ability of a material to build up a static charge as well as the tendency to dissipate one. When you rub a balloon against a carpet of a piece of clothing, it will stick to the wall without any adhesives. Can formation of electrostatic charges be realistically eliminated? This is also true for people who mix some gasoline with their diesel fuel in the winter. 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. a very high speed. What are the Claims of Anti-Fracking Activists? causes a spark. the fuel. or ESD. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. . positive) as it leaves the sprayer, This ensures that the spray remains fine and covers a large area, They are also attracted to the negative charges on Earth, so they will fall, A similar technique is used in the spray painting of cars. Insulators prevent the electrons from moving and the charge remains static. On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. large surface area and 0000001087 00000 n The best approach is precaution resulting in prevention by sterilization. We use cookies to ensure that we give you the best experience on our website. Consider an N2\mathrm{N}_2N2 molecule in its first excited electronic state, that is, when an electron in the highest occupied molecular orbital is promoted to the lowest empty molecular orbital. This will reduce any potential shock. mats are also a basic low-cost means of reducing electrical FOD. This is why, especially with fiberglass or composite aircraft, the owner needs to check with an ohmmeter to ensure that there is an electrical path from thecontact point to the filler neck. If the charge is very large, a spark to. 0000002998 00000 n that causes the buildup of electrical charges and not the effect of heat. Ashika graduated with a first-class Physics degree from Manchester University and, having worked as a software engineer, focused on Physics education, creating engaging content to help students across all levels. or rack supporting the unit to be replaced for several seconds. Why is static electricity dangerous when Refuelling an aircraft? Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home. Do not re-enter your vehicle during refueling. refuelling. Place cap tightly on the container after filling - do not use containers that do not seal properly. You may apply lotion or moisturizer on your . very quickly because it has a very 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. If the charge is of sufficiently high potential, it can cause sparking within the aircraft or the origin storage tank. Neither crew nor ATC requested a runway inspection and 12 further aircraft movements occurred before it was closed for inspection and recovery of 14 kg of debris. When refuelling an airplane, the airplane might be charged due to friction between the plane and the air when the plane was flying, causing electrons to transfer. happens If the charge is very large, a spark to the earth may happen unexpectedly. Keep your face away from the nozzle or container opening. Use only the refueling latch provided on the gasoline dispenser nozzle. Static electricity is created by the friction of air with an aircraft in flight and the electrical charge remains static, or still, until it accumulates sufficiently to discharge (when RFI is usually generated) and neutralize the accumulated charge. GCSE Chemistry 0000074721 00000 n Sparks like this can be dangerous, potentially igniting a fire. It may be a one in a million chance but there is a danger that static electricity may ignite the gasoline vapours during refueling at a petrol station. a flash fire or small sustained fire with gasoline refueling vapors. 0000001180 00000 n 0000007851 00000 n This may happen safely by connecting them to the earth with a conductor. way The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. As these problems worsened, one engine became unusable and a PAN and then a MAYDAY were declared prior to a successful landing at destination with excessive speed after control of thrust from the remaining engine became impossible.
