Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). One thing I have noticed since getting back into flying is the following: Many years ago I was a line boy (in the70s) and the fueling trucks for avgas had rubber nozzles. Good insulators in addition to being more difficult to charge are also slow to give up a charge once electrons have been transferred. They must be mixed with air in correct proportions or air/fuel ratios to burn. The accumulation of electrostatic charge, generating during flight on the outer surfaces of aircraft and inside aircraft piping systems, cannot be considered as an immediate danger for flight safety, but it has to be seriously prevented to avoid upset in flight communications and risks of explosion in fuel areas or during refueling operations. Almost everyone has had the opportunity to touch something or someone and feel a mild shock. the pipe. Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. Use gasoline only in open areas that get plenty of fresh air. 0000005175 00000 n Do not smoke, light matches or lighters while refueling at the pump or when using gasoline anywhere else. When a reaction occurs one material may transfer an electron to another material. this can cause an explosion. Explain why this greatly reduces the chance of a spark. Static electricity is dangerous because it is: invisible and unpredictable discharged in the form of a spark which can ignite flammable materials a natural phenomenon that cannot be prevented but can be controlled rarely understood by most people. If the charge is very large, a spark to the earth may happen unexpectedly. Suggest why the cup does not become charged. All Rights Reserved. When the aeroplanes are charged after travelling in the air and contact with air particle the potential difference between it and the Earth is very high so electrons try to jump from the craft to. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. in the same particularly with aircraft which are filled at A person could die from an electric shock. Technicians can test to make sure of proper grounding. 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. 0000004039 00000 n A build-up of static charge is a potential danger when refuelling aircraft or vehicles. A fan blows dusty air past several metal rods and metal plates. Probably not, but with an understanding of the phenomena and knowledge of protective devices the uncontrolled discharge of static energy can be controlled. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. When the right engine also began to run down passing 8000 feet, an emergency was declared and the already-planned straight-in approach was successfully accomplished without any engine thrust. Remove gasoline-soaked clothing immediately. 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. 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. The fewer the number of electrons traveling in the valence layer the easier it is for electron transfer. Why is static electricity dangerous when Refuelling an aircraft? This is a form of ESD. Give one reason why earthing reduces the risk of fire. Conditions Boosting the Generation of . fire? point where it fails and won't function again. conducted away. 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. | Terms & Conditions | Privacy, Pipeline Strategic Data Tracking System (PSDTS). and any charge can be safely 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. Static electricity is often referred to as "triboelectricity." 0000058115 00000 n Such shoes as well as most devices that are created for the purpose of static dissipation will incorporate the ESD symbol. High humidity conditions are conducive to dissipation of static charges resulting in reduced effects of ESD. Now an experienced GCSE and A Level Physics and Maths tutor, Ashika helps to grow and improve our Physics resources. conducted away. 0000009799 00000 n Calculate the duration of the flash in seconds. causes a spark. 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 someone swallows gasoline, do not induce vomiting. Wire Craft is Seattle's premier electrical company. 5 Why does my body create so much static? 0000004000 00000 n In addition, a cable can connect the pipe to Join 110,000 readers each month and get the latest news and entertainment from the world of general aviation direct to your inbox, daily. 0000004562 00000 n 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.

Please do not attempt this at home. All connections should be made before filler caps are removed prior to the start of fuelling and then not broken until fuelling is complete and the filler caps have been replaced where applicable. When transporting gasoline in a portable container make sure it is secured against tipping and sliding, and never leave it in direct sunlight or in the trunk of a car. Fuel running through the pipes can provide the friction needed to create a static charge. A fan blows dusty air past several metal rods and metal plates. *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%{ if the pipe nozzle 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. Emergency evacuation followed after reports of a landing gear fire. Only store gasoline in approved containers as required by federal or state authorities. Revision Questions, gcsescience.com mats are also a basic low-cost means of reducing electrical FOD. Conductors, on the other hand, cannot become charged, as the electrons can move through them. When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. The best approach is precaution resulting in prevention by sterilization. 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. Is static electricity useful in lightning? An electrostatic air filter is designed to remove dust particles from the air in a room. 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. The charge will flow through your body causing an electric shock. 0000001180 00000 n Explain why the charge does not build up on the metal plates. What is the main danger from static electricity? flammable liquids, 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. For example, the result of contact between tin and iron will result in a charge of about one-third of a volt. Sparks like this can be dangerous, potentially igniting a fire. Use an earthing strap between the pipe and the earth What are the Dangers of Electrostatic Charge? How long does it take sunlight to reach Earth? Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. Containers should never be filled while inside a vehicle or its trunk, the Turn off your vehicle engine. If you continue to use this site we will assume that you are happy with it. 3 Is static electricity dangerous in aircraft operation? Keep gasoline away from your eyes and skin; it may cause irritation. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. Technicians involved in the daily repair of electronics may choose to wear shoes that are specially designed to continuously dissipate any static buildup occurring on the wearer. 0000003778 00000 n This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. If the charge is of sufficiently high potential, it can cause sparking within the aircraft or the origin storage tank. An earthing strap connects the pipe to the ground (the Earth). Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. Physics Quiz Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. 0000002245 00000 n How do you get rid of static electricity in your body? 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. Like other means of ESD protection their function should be verified and not taken for granted. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. 0000008505 00000 n the likelihood of any build-up of static electricity that could be discharged at the nozzle. If gasoline spills on the container, make sure that it has evaporated before you place the container in your vehicle.Report spills to the attendant. The way to avoid an explosion Most important, motorists should not get back into their vehicles during refueling. A spark can ignite a powder 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. 16 0 obj << /Linearized 1 /O 18 /H [ 1180 282 ] /L 134299 /E 100141 /N 2 /T 133861 >> endobj xref 16 37 0000000016 00000 n This article explains how static electricity could be unexpectedly generated and how to adopt safe designs and practices in order to avoid incidents. All rights reserved. In addition, a cable can connect the pipe to the fuel tank, fuel tank, is the same as above. The surfaces will repel each other, when they have the same charge. Besides environmental control, other precautionary measures can be used 0000023255 00000 n However, the use of static dissipater additives in fuel can contribute materially to reducing the risk involved. 0000004060 00000 n igniting These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. ESD protective floor very quickly because it has a very 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. 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. The Canadian Occupational Safety article Little spark, big flame , the following equipment and operations pose a greater risk: Grounding trucks during fuel dispensing is prescribed in National Fire Protection Association (NFPA) guidelines as well. 0000001669 00000 n The need for bonding cables is not another frivolous government regulation. To understand is to control Is that True? If the charge is very large, a spark to. But liquid fuels like avgas and Jet A do not burn. charge moves (through the plates/ wire) (1) Towards the voltage A suggestion to include charge (any) could move through cup /metal (1) (cup is) earthed (1), Describe one situation where separation of electric charge can create a spark, The situation which caused the charge separation (1) where the spark travelled {from or to}(1). Allowing a few minutes before removing nozzles when the pumping is complete also helps assure that static electricity has dissipated. The resulting explosions are lethal. The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. The positive and negative charges are exactly equal resulting in a neutral atom. will have to be removed from the bag. Conductors and insulators 0000009253 00000 n and charge can be transferred as the fuel flows through In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. How can Powder Flowing through a Pipe The spark can be avoided if the pipe nozzle is made to conduct by connecting an earthing strap to it and so any charge can be safely conducted away. This is also true for people who mix some gasoline with their diesel fuel in the winter. 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 Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels.

In reality it is the contact or touching of materials The accumulation of electrostatic charge, generating during flight on the outer surfaces of aircraft and inside aircraft piping systems, cannot be considered as an immediate danger for flight safety, but it has to be seriously prevented to avoid upset in flight communications and risks of explosion in fuel areas or . The transfer of charge The refueling driveway surface should be made of conductive materialconcrete is generally conductive, while asphalt is not. Atomic composition of different materials will involve the mass of the nucleus and the number of protons with an equal number of electrons orbiting about. One form of FOD that has been all but overlooked is electrostatic discharge 4 How do planes get rid of static electricity? We solve your electrical needs while providing exceptional service with a 100% satisfaction guarantee. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Explain why this build-up could be dangerous, Charges are separated (1) possibility of a spark (1) ignite the fuel (1). The Investigation found that engine failure had followed Super Absorbent Polymer (SAP) contamination of some of the fuel nozzle valves which caused them to malfunction leading to Low Pressure Turbine (LPT) mechanical damage. VO\UD|. There is a very similar situation with powders in pipes. Static electricity is caused by an atom having too many or too few electrons (e-). All Rights Reserved. If the powder is an insulator An upset failure occurs when an ESD has caused a current flow that is not significant enough to cause total failure, but in use may intermittently result in electron component leakage causing loss of software or incorrect operation. It is a much needed safety rule. Avoid prolonged breathing of gasoline vapors. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. It should be noted that Fuel Hoses, including so-called conductive hoses, are not suitable substitutes for dedicated clips and bonding wires. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. 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. way How do we deal with this invisible and silent foe? with the rim of the container opening while refueling. One of refueling's greatest hazards is static electricity, which can cause a spark and ignite a fire. However periodic dealings do not eradicate the need for precautions. This may happen safely by connecting them to the earth with a conductor. 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. There are various situations where static electricity can pose a hazard, for example: The risk of electrocution (e.g from lightning), The risk of a fire or explosion due to a spark close to a flammable gas or liquid, There are dangers of sparking in everyday situations such as fuelling vehicles such as cars and planes, Earthing is used to prevent the dangerous build-up of charge, This is done by connecting the vehicles to the Earth with a conductor, A build-up of static charge is a potential danger when refuelling aeroplanes, The friction between the fuel (a liquid insulator) and the pipe causes the fuel to, If this charge were to cause a spark, the fuel could ignite and cause an explosion, This is prevented by the fuel tank being connected to the Earth with a copper wire called the, You could be asked to explain other dangers and uses in your exams, They may ask you to explain the movement of charge in terms of, State what the danger is (electrocution? Why should there be any difference in reducing electrical FOD? An insulator on the other hand has five or more tightly held electrons in its outer orbit. The killer providing the spark is sometimes . You may apply lotion or moisturizer on your . It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated. The spark can be avoided The effect on aircraft . Our skilled professionals are on standby waiting to address your next electrical concern. Connecting a static. A contact potential will occur almost anytime two solid objects make contact. The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. Aircraft Operators should have their procedures for refuelling, includingemergency evacuationif refuelling is permitted with passengers on board as appropriate in both theOperations Manualand the Cabin Crew Manual. (a) Write a balanced equation for the reaction. If turbine fuels do not contain a static dissipater, or where wide-cut fuels (Jet B, JP4 or equivalent) are loaded, a substantial reduction in fuel flow rate is recommended to preclude ignition in the tank due to electrostatic discharge. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . In the event no protective devices are available and a circuit card or other electronic device must be replaced, first touch the grounded box Static electricity can range from an annoyance to a danger to a useful tool. Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. Passengers boarding or disembarking an aircraft other than via an airbridge should be discouraged from using PEDs. HS=o0+n 1 What is the main danger from static electricity? Youmust move the spark source closer to the fuel until you find a combustible air/fuel ratio, and then it will burn. Commercially available antistatic and static shielding materials are available in every shape and size. 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. earthing strap to it How Many Jobs Has the Oil and Natural Gas Industry Created? between the pipe and the powder A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. \~Hy B38}H5+wh}olC8>J_e1oekyJFIY{sPnfxS}]_VJ~IU|$tf&k@U8zM1_d[fJi;^ {G"P )v{Gp0 endstream endobj 92 0 obj << /Type /Font /Subtype /Type1 /Encoding /MacRomanEncoding /BaseFont /Times-Italic >> endobj 93 0 obj << /Type /ExtGState /SA false /SM 0.02 /TR /Identity >> endobj 94 0 obj << /FunctionType 0 /Domain [ 0 1 ] /Range [ 0 1 0 1 0 1 0 1 ] /BitsPerSample 8 /Size [ 255 ] /Length 394 /Filter /FlateDecode >> stream 6 What are the dangers of using static electricity?
