%PDF-1.3 % Revision Questions, gcsescience.com Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. 0000009232 00000 n igniting (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). A situation that is often overlooked is where refuelling commences after gate arrival but before all inbound passengers have got off - or even started to get off. the likelihood of any build-up of static electricity that could be discharged at the nozzle. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. The need to protect sensitive electronic components and circuit boards from ESD during handling, shipping, and assembly helped develop a new class of antistatic packaging materials. Technicians can test to make sure of proper grounding. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. gcsescience.com, Home Aircraft electrical racks also have a very low resistance path to the aircraft structure. Sparks like this can be dangerous, potentially igniting a fire. The aircraft is also connected by a metal cable to the refuelling tanker. Conductors, on the other hand, cannot become charged, as the electrons can move through them. There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. particularly with aircraft which are filled at a very high speed. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize 5 Why does my body create so much static? 0000007608 00000 n Physics Quiz State what happens to the charge on the dust particles when they settle on the metal plates. Damage to components. Can formation of electrostatic charges be realistically eliminated? just like it can ignite a flammable liquid or vapour. Conditions Boosting the Generation of . 0000007830 00000 n Identify the molecular orbitals involved, and sketch a diagram to show the transition. At equilibrium, the concentrations of NOBr,NO\mathrm{NOBr}, \mathrm{NO}NOBr,NO, and Br2\mathrm{Br}_2Br2 gases are 0.0162M0.0162 \mathrm{M}0.0162M, 0.0011M0.0011 M0.0011M, and 0.072M0.072 M0.072M, respectively. When the aircraft charge is great enough, it discharges into the surrounding air. happens The hydrogen atom is the simplest as well as the lightest. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). On 9 May 2019, a Cessna 550 level at FL 350 experienced an unexplained left engine rundown to idle and the crew began descent and a diversion to Savannah. 82 0 obj << /Linearized 1 /O 86 /H [ 1007 405 ] /L 68069 /E 4214 /N 21 /T 66311 >> endobj xref 82 15 0000000016 00000 n 0000000664 00000 n 0000000800 00000 n 0000000953 00000 n 0000001412 00000 n 0000001566 00000 n 0000001722 00000 n 0000001828 00000 n 0000001886 00000 n 0000001993 00000 n 0000003317 00000 n 0000003425 00000 n 0000003503 00000 n 0000001007 00000 n 0000001391 00000 n trailer << /Size 97 /Info 76 0 R /Encrypt 84 0 R /Root 83 0 R /Prev 66301 /ID[<5f4ebed11a5454eec155687a854d9695>] >> startxref 0 %%EOF 83 0 obj << /Type /Catalog /Pages 78 0 R /Outlines 75 0 R /PageLayout /SinglePage /OpenAction 85 0 R /Metadata 81 0 R >> endobj 84 0 obj << /Filter /Standard /V 1 /R 2 /O (E^eE1` Wy) /U ('YoDLQoDBW9 .$s) /P 65476 /Length 40 >> endobj 85 0 obj << /S /GoTo /D [ 86 0 R /Fit ] >> endobj 95 0 obj << /S 273 /O 335 /Filter /FlateDecode /Length 96 0 R >> stream Place cap tightly on the container after filling - do not use containers that do not seal properly. 0000001441 00000 n s 7^ Ak# endstream endobj 52 0 obj 170 endobj 18 0 obj << /Type /Page /Parent 13 0 R /Resources 19 0 R /Contents [ 28 0 R 30 0 R 32 0 R 34 0 R 36 0 R 40 0 R 42 0 R 44 0 R ] /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 19 0 obj << /ProcSet [ /PDF /Text ] /Font << /TT2 24 0 R /TT4 20 0 R /TT6 21 0 R /TT8 37 0 R >> /ExtGState << /GS1 47 0 R >> /ColorSpace << /Cs6 26 0 R >> >> endobj 20 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 121 /Widths [ 278 0 0 0 0 0 722 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 667 611 0 0 0 0 0 0 0 0 778 0 0 0 667 0 0 0 0 0 0 0 0 0 0 0 0 0 556 0 556 0 556 0 611 0 278 0 0 278 0 611 611 611 0 389 556 333 611 0 0 0 556 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHBP+Arial,Bold /FontDescriptor 22 0 R >> endobj 21 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 150 /Widths [ 250 0 0 0 0 0 0 278 0 333 0 0 250 333 250 278 0 500 500 500 500 0 0 0 0 0 333 0 0 0 0 0 0 722 0 0 722 667 611 778 0 389 0 0 667 944 722 778 611 0 722 556 667 722 722 0 0 0 0 0 0 0 0 500 0 500 556 444 556 444 333 500 556 278 0 556 278 833 556 500 556 556 444 389 333 556 500 722 0 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHDB+TimesNewRoman,Bold /FontDescriptor 25 0 R >> endobj 22 0 obj << /Type /FontDescriptor /Ascent 905 /CapHeight 0 /Descent -211 /Flags 32 /FontBBox [ -628 -376 2000 1010 ] /FontName /LPDHBP+Arial,Bold /ItalicAngle 0 /StemV 133 /FontFile2 45 0 R >> endobj 23 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 656 /Descent -216 /Flags 34 /FontBBox [ -568 -307 2000 1007 ] /FontName /LPDHBN+TimesNewRoman /ItalicAngle 0 /StemV 94 /XHeight 0 /FontFile2 46 0 R >> endobj 24 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 150 /Widths [ 250 0 408 0 0 0 0 0 333 333 0 0 250 333 250 278 500 500 500 500 0 500 0 0 500 0 278 0 0 0 0 0 0 722 667 667 722 611 556 722 722 333 0 0 611 889 722 722 556 0 667 556 611 722 722 944 0 0 611 0 0 0 0 0 0 444 500 444 500 444 333 500 500 278 0 500 278 778 500 500 500 500 333 389 278 500 500 722 500 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHBN+TimesNewRoman /FontDescriptor 23 0 R >> endobj 25 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 656 /Descent -216 /Flags 34 /FontBBox [ -558 -307 2000 1026 ] /FontName /LPDHDB+TimesNewRoman,Bold /ItalicAngle 0 /StemV 160 /FontFile2 50 0 R >> endobj 26 0 obj [ /ICCBased 48 0 R ] endobj 27 0 obj 424 endobj 28 0 obj << /Filter /FlateDecode /Length 27 0 R >> stream } '+.$wY .

Encased equipment should always have protective covers placed over the electric connectors and care should be exercised to avoid direct contact with electrical pins. To understand is to control %PDF-1.4 % [[{>&@}M Avoid prolonged breathing of gasoline vapors. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. Procedures for Emergency Passenger Evacuation should take account of the availability or otherwise of airbridge access and in-position ground steps in the selection of exits to be used. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. . 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. HS=o0+n On 16 April 2014, a pre-flight concern about whether a Boeing 777-200ER about to depart Singapore had been overfuelled was resolved by a manual check but an en-route fuel system alert led to close monitoring of the fuel system. When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. If thegrounding point on your aircraft does not have electrical conductivity with the filler neck, then when the hose is placed in the neck or during the fueling process, the electrical potential will not be equalized and a spark can occur. 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. The average current is 2600 A. Awareness and precaution key have resulted in a brief flash fire occurring at the fill point. 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. 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. Use an earthing strap between the pipe and the earth The surfaces will repel each other, when they have the same charge. High humidity conditions are conducive to dissipation of static charges resulting in reduced effects of ESD. Insulators prevent the electrons from moving and the charge remains static. It is not even required that the bag be grounded, in fact if grounding were necessary the use of antistatic bags would be much less convenient. He has been a private pilot since 1985. Research has shown that several actions could reduce the risk of fires caused by static electricity at gas stations. 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. 2023 Flyer Media, Inc. All rights reserved. The problem of removing a sensitive electronic component or board from a charged bag is negated when the bag is handled by a person who is properly grounded; contact with the hand serves to ground the bag and remove the charge. Salt water contamination of the hydrant fuel system at Surabaya after alterations during airport construction work was found to have led to the appearance of a polymer contaminant in uplifted fuel. Today, we will talk about static electricity, the dangers of this common occurrence, and tips on how to protect yourself from injury or property damage. Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. Electricity is an important part of our lives, but we always have to treat it with respect and care. Calculate the duration of the flash in seconds. Why should there be any difference in reducing electrical FOD? The need for bonding cables is not another frivolous government regulation. Can a small spark from static electricity cause an explosion? Consumers can take steps to minimize these and other potential fueling hazards by following safe refueling procedures all year long. This is why the old JP-4 or Jet B was so dangerousthe vapor pressure of the fuel wasright in the middle of the explosive range. charge moves (through the plates/ wire) (1) Towards the voltage at velocities below 1 m/s, no dangerous charges will be generated; Flanges should be earth bonded; Use sub-surface dip pipes or bottom . The metal cup does not become charged when she rubs the trophy. An electrostatic air filter is designed to remove dust particles from the air in a room.

Use only the refueling latch provided on the gasoline dispenser nozzle. Have you experienced getting jolted by a spark of electricity when you touched a door knob or hand rail? Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. 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. People have been killed or severely hurt doing something as simple as refueling their vehicle or gas container. (Note that the gases need to be expressed as pressure in atm. Copyright 2015 gcsescience.com. VO\UD|. 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. mats are also a basic low-cost means of reducing electrical FOD. Therefore triboelectricity is a form of electricity produced by rubbing. Todays trucks have metal nozzles. 3 Is static electricity dangerous in aircraft operation? A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. Keep gasoline away from your eyes and skin; it may cause irritation. (a) Write a balanced equation for the reaction. This results in a change in the state of charge. This will reduce any potential shock. Download PDF Test Yourself. ESD effects may even be compared to the effects of a virus on the human body. 0000004562 00000 n supply / earth /ground If you cannot avoid re-entering your vehicle, discharge any static build-up BEFORE reaching for the nozzle by touching something metal with a bare hand -- such as the vehicle door -- away from the nozzle.). Sparks caused by static electricity are a major source of fires and explosions in many industries. Direct catastrophic failures occur when a component is damaged to the Notify the station attendant immediately. 2.4.4 Uses & Dangers of Static Electricity. Static Electricity Can Cause Fires! 0000006537 00000 n Electrons in the outermost orbit may be either firmly or weakly attached.

An earthing strap connects the pipe to the ground 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. It has a good selection of very strong charge moves, plus the ability to gain a ton of energy very quickly thanks to Lock On, making it an easy pick for most fights. Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. This is also true for people who mix some gasoline with their diesel fuel in the winter. 0000007195 00000 n 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. 0000001840 00000 n 52 = 2600 x time transposition time = 52 / 2600 (1) evaluation 0.02 (s). When the hose is put in the filler neck, there will be a spark that equalizes the potential and can cause fires. A humidifier may do the trick. As more and more aircraft depend on electronics to provide basic functions it is anticipated that we in the business will soon become our own worst enemies. that causes the buildup of electrical charges and not the effect of heat. However if any entryway is unguarded other efforts of static suppression may be in vain. With Jet A, as with diesel fuel, the vapor pressure of the fuel is low so that the air/fuel ratio at the neck is too lean to burn, sothe chance of a fire is very low. 0000005874 00000 n To control the effects of static electricity and for . But liquid fuels like avgas and Jet A do not burn. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . 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. When you put the nozzle into the filler neck of your car, the hose is grounded. Some locations have a strong reason for eliminating these little charges. Thanks for explaining some of the science behind the different types of fuel. Ive seen a couple of those result in static electricity fires that did tremendous damage. Emergency evacuation followed after reports of a landing gear fire. WJhE7,> mo9?]RC"iGJ$iZt)6fVCPN|B{`m'i! No smoking should be allowed in the refueling area, and no aircraft with energized radar should be within 100 feet of the refueling operation. that will greatly reduce the possibility of ESD. HtTo0xG@r*\0c3$Jg'MeR$|eOWo7*YY5lUAKG6(?Ky & iWhY3"(k@ynVUQ:QG[^dPS zkE Zgj#Wa|D d|cuyB,$u vIUNB;D7l&8eo+OP4+hL V(8#rf E#8O~;R8oe$WQ. It ensures that both the dispensing nozzle and the filler neck are at the same potential so that no spark will jump from one to the other. Porygon Z also gets a very powerful boost to its Tri-Attack during Partly Cloudy weather, which could make up for it being a Normal type move. They work on the same principle as a high resistance ohmmeter. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. Is static electricity dangerous in aircraft operation? Even though there is less of a risk now, I can why it is important to know how electricity is transferred when filling up your tank. This way the static from your body will be discharged before you remove the nozzle. Static electricity is caused by an atom having too many or too few electrons (e-). In addition, a cable can connect the pipe to The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. In the event no protective devices are available and a circuit card or other electronic device must be replaced, first touch the grounded box will have to be removed from the bag. To understand static charges we have to first have a grasp of the atom. 0000007851 00000 n Catastrophic failures occur in two forms, direct and latent. Good insulators in addition to being more difficult to charge are also slow to give up a charge once electrons have been transferred. The spark can be avoided Why is static electricity dangerous when Refuelling an aircraft? Explain why this greatly reduces the chance of a spark. Consider the decomposition at 25C25^{\circ} \mathrm{C}25C of one mole of NOBr\mathrm{NOBr}NOBr gas into NO\mathrm{NO}NO and Br2\mathrm{Br}_2Br2 gases. Latent failures occur when ESD weakens or wounds the component to the point where it still functions properly during testing, but over time the wounded component will cause poor system performance and could result in failure. Wrist straps also counter unwanted static discharge. 4 How do planes get rid of static electricity? What does a bonding cable do? 7 earthing strap to it Put your vehicle in park and/or set the emergency brake. If someone swallows gasoline, do not induce vomiting. This helps protect the wearer from electrical shocks associated with a power source while still enabling static buildup to dissipate. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. The transfer of charge across an air gap it The article also states that the aircraft is connected by a metal cable to the ground. One of the most common occurrences of static electricity dangers is refueling a vehicle. Our skilled professionals are on standby waiting to address your next electrical concern. Do not smoke, light matches or lighters while refueling at the pump or when using gasoline anywhere else. Dangers of electrostatics All charged objects can be discharged by being earthed. However periodic dealings do not eradicate the need for precautions. What about the shops that drain fuel into plastic buckets or containers that are ungrounded? The issues are much the same whether the fuel source is a tanker/bowser or a fuel hydrant system. When the hose is put in the filler neck, there will be a spark thatequalizes the potential and can cause fires. The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. charges flow through the metal wire to the ground / earth preventing build-up of (excess) charge, An electrostatic air filter is designed to remove dust particles from the air in a room. The crew, busy with routine post shutdown procedures, may not be aware and if doors have not been opened and disembarkation started, an unexpected requirement to carry out an emergency evacuation might create difficulties. 0000058037 00000 n When a reaction occurs one material may transfer an electron to another material. It also appears that PEDs close to or on board modern aircraft can interfere with fuel gauges and some navigation equipment and may cause false fire warnings in cargo/baggage holds. Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. Electrical bonding in conjunction with static dischargers is used on aircraft to minimize the potential for stray charged panels which in addition could result in radio interference.
