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. Copyright 2021 - API. Saint Elmo's Fire is the common name for this corona discharge effect. Static electricity is created when objects with different electrical properties come into contact, and negatively charged electrons from one substance are transferred to the other. 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 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. 0000006537 00000 n Emergency evacuation followed after reports of a landing gear fire. The result is a ghostly glow visible often in low light conditions. To control the effects of static electricity and for . They were very professional both times. The transfer of charge Pumping fuel into an aircraft can be dangerous. Can a small spark from static electricity cause an explosion? What changed? When to ground a fire truck for static electricity? Revision Questions, gcsescience.com (the Earth). 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. How can Powder Flowing through a Pipe When a reaction occurs one material may transfer an electron to another material. GCSE Physics. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. ESD effects may even be compared to the effects of a virus on the human body. On a piston aircraft, the vapor pressure of the fuel is less than that of auto gas and the filler neck is more out in the open where the wind can easily raise the air/fuel ration at the filler neck into the explosive range. Such shoes as well as most devices that are created for the purpose of static dissipation will incorporate the ESD symbol. Is that True? 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. Besides environmental control, other precautionary measures can be used Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. 0000023255 00000 n 1 What is the main danger from static electricity? (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). or ESD. What can be done about gas station fires caused by static electricity? In addition, a cable can connect the pipe to Allowing a few minutes before removing nozzles when the pumping is complete also helps assure that static electricity has dissipated. In rare circumstances, these static related incidents A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. The average current is 2600 A. However periodic dealings do not eradicate the need for precautions. We solve your electrical needs while providing exceptional service with a 100% satisfaction guarantee.

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. 2 Why is static electricity dangerous when Refuelling an aircraft? 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. through a Pipe cause an Explosion? These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. 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. He's completed a number of projects and there are several more in the planing phase. Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home. Encased equipment should always have protective covers placed over the electric connectors and care should be exercised to avoid direct contact with electrical pins. Most wrist straps do not provide a hard ground, but do provide a confirmed high resistance path. 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. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. All Rights Reserved. A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. Do not re-enter your vehicle during refueling. Josh is now my go to Electrician! charge moves (through the plates/ wire) (1) Towards the voltage Static electricity along with too much heat can ignite these products. Wrist straps also counter unwanted static discharge. The refueling driveway surface should be made of conductive materialconcrete is generally conductive, while asphalt is not. 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 . if the pipe nozzle Electrons in the outermost orbit may be either firmly or weakly attached. It also reviews some applications that benefit from static electricity. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. The spark can be avoided There is a large potential difference (voltage) between the metal rods and the metal plates. Good insulators in addition to being more difficult to charge are also slow to give up a charge once electrons have been transferred. GCSE Chemistry A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Whats the Difference Between Wastewater Disposal and Fracking? 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. 0000003778 00000 n . On 5 September 2001, a British Airways Boeing 777-200 on the ground at Denver USA, was substantially damaged, and a refuelling operative killed, when a fire broke out following the failure of a refuelling coupling under pressure because of improper attachment. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. . Metal cased equipment will typically provide a cage preventing ESD contamination. What are the Dangers of Electrostatic Charge? Conductors and insulators You can add humidity to the air to help with this. A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. Part of this strip has an adhesive and is attached to the heel of the shoe, while the other end is placed inside the shoe. Static electricity-related incidents at retail gasoline outlets are extremely unusual, but the potential for them to happen appears to be the highest during cool or cold and dry climate conditions. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. If you need help assessing the electrical safety of your home, dont hesitate to call us at Wire Craft Electric. It may be a temptation to get back in the car for any number of reasons. Direct catastrophic failures occur when a component is damaged to the This fuel is very flammable; The friction between the fuel . What does a bonding cable do?

Use only the refueling latch provided on the gasoline dispenser nozzle. During the lightning flash a total charge of 52 C flows. But liquid fuels like avgas and Jet A do not burn. How can Fuel Flowing Insulators prevent the electrons from moving and the charge remains static. If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing Have you experienced getting jolted by a spark of electricity when you touched a door knob or hand rail? The conductivity of the fuel should be examined and considered. 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 person could die from an electric shock. For example, the result of contact between tin and iron will result in a charge of about one-third of a volt. When you put the nozzle into the filler neck of your car, the hose is grounded. } '+.$wY . G=Po9dByh|q[6luvSe*Fn!yc[ T"%*Lp{v*dO Cu! The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. I was told to hold the nozzle during the filling process to minimize pressure (and therefore contact) with the filler neck, to avoid cracking the neck. If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing a flash fire or small sustained fire with gasoline refueling vapors. Todays trucks have metal nozzles. The charge will flow through your body causing an electric shock. A key function of equipment earthing is to provide a controlled method to prevent the build up of static electricity, thus reducing the risk of electrical discharge in potentially hazardous environments. 2023 Flyer Media, Inc.

Investigating Radiation, Electrostatic charges are used in everyday situations such as photocopiers and inkjet printers, Photocopiers use static electricity to copy paper documents, most commonly in black and white, An image of the document is projected onto a positively charged copying plate, The plate loses its charge in the light areas and keeps the positive charge in the dark areas (i.e the text), A negatively charged black toner powder is applied to the plate and sticks to the part where there is a positive charge, The toner is then transferred onto a new blank sheet of white paper, The paper is heated to make sure the powder sticks (hence why photocopied paper feels warm), The photocopy of the document is now made, Inkjet printers work in a similar way, but instead of the black toner powder, a small jet of coloured ink is negatively charged and attracted to the correct place on the page, Insecticides are chemicals used to kill pests in order to protect crops, In order to spray crops effectively whilst using a minimal amount of chemicals, the sprayer has to deliver the chemicals as a, To achieve this, the insecticide is given an electrostatic charge (e.g. s 7^ Ak#

stream Like other means of ESD protection their function should be verified and not taken for granted. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. Pressure refuelling is normal for multi crew transport aircraft and business jets but gravity refuelling of these types may be available as a backup system. 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. This could cause burns or even stop your heart. There is a very similar situation with powders in pipes. How is Groundwater Protected During Hydraulic Fracturing? 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 in the wrong environments, however, may be dangerous. Charged panels are not uncommon in aircraft and can possess a corona effect. Index Explain why this build-up could be dangerous, Charges are separated (1) possibility of a spark (1) ignite the fuel (1). 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. Fuel running through the pipes can provide the friction needed to create a static charge. 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. 0000007608 00000 n 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 .$s) /P 65476 /Length 40 >> endobj 85 0 obj << /S /GoTo /D [ 86 0 R /Fit ] >> endobj 95 0 obj << /S 273 /O 335 /Filter /FlateDecode /Length 96 0 R >> stream Ben Visser is an aviation fuels and lubricants expert who spent 33 years with Shell Oil. trailer << /Size 53 /Info 14 0 R /Root 17 0 R /Prev 133851 /ID[] >> startxref 0 %%EOF 17 0 obj << /Type /Catalog /Pages 13 0 R /Metadata 15 0 R /PageLabels 12 0 R >> endobj 51 0 obj << /S 87 /L 194 /Filter /FlateDecode /Length 52 0 R >> stream On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. Electrostatic Charge No smoking should be allowed in the refueling area, and no aircraft with energized radar should be within 100 feet of the refueling operation. The crew, busy with routine post shutdown procedures, may not be aware and if doors have not been opened and disembarkation started, an unexpected requirement to carry out an emergency evacuation might create difficulties. is made to conduct by connecting an b8+ '!"3w=f94s!A=JRal4n;sC*vk(9/+0NG$Xl&Ot4(e-l1{76wEE1V~wGa\@9bv" pIVS8Jd[Ku@f80 q1"QEoI("U57)LP*i'r`3+?] U,iK#|W'TIu5 F?q!ogyj+x&_S^v]8/~#$AxLc&JfCcfPmZ#A\+Kct"d{eEV.P5j"nG: gp2-@gAB3R6Riy]en>s~E*]0/`~[byQ)kb_}6PQuIu/'D9uK0={qcu3Hu|/pyDOQ; The resulting explosions are lethal.

Turn off your vehicle engine. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. What are the Claims of Anti-Fracking Activists? Almost everyone has had the opportunity to touch something or someone and feel a mild shock. 0000006516 00000 n The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. 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 a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. Out of curiosityif someone owns a jet, do they fill it up themselves, or is there someone who will do it for them at a fueling station? Explain how these cables reduce the dangers when refuelling the aircraft. 2.4.4 Uses & Dangers of Static Electricity. will have to be removed from the bag. 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. 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. 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. Avoid prolonged breathing of gasoline vapors. 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. Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. 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. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. This will reduce any potential shock. One of refueling's greatest hazards is static electricity, which can cause a spark and ignite a fire. Electricity is an important part of our lives, but we always have to treat it with respect and care. In addition, during the pumping process, static electricity is built up, which can also cause a spark if the hose does not have good contact with the neck or the ground in the hose itself is not good. When insulating materials are rubbed together, electrons are knocked off one of them and onto the other. How Much Water Does Hydraulic Fracturing Use? We are all aware of the result when a foreign object enters the inlet of a turbine engine or when the wing of a moving aircraft comes in contact with a stationary rigid object like the hangar wall. Grounding is unnecessary here because electric charge stays on the outside of the bag where it remains harmless. This results in a change in the state of charge. This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. Aircraft electrical racks also have a very low resistance path to the aircraft structure. Electrostatic Charge Quiz The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. 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. Why is static electricity dangerous when Refuelling an aircraft? "Excellent work and workmanship. %PDF-1.4 % Notify the station attendant immediately. Name the kinds of evidence that systematists use in constructing a phylogenetic tree. Electrical bonding must be used to eliminate this hazard. Sparks like this can be dangerous, potentially igniting a fire. Now an experienced GCSE and A Level Physics and Maths tutor, Ashika helps to grow and improve our Physics resources. For example, if you suspend a spark plug 0.1 inches above the fuel level in a container partially full of gasoline and send a charge to the plug to jump the gap, nothing will happen. 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. 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. As the nozzle (the end) of the pipe is 0000001840 00000 n Using lotions and moisturizers before getting dressed and throughout the day will help keep static electricity from accumulating on your body. g~:-A`qK#P O|{{1*T _{MA}gk MC1a!PqLKTEat5(B)jn?oS{}Wd@JY4pnxv Hxhb1$aF Containers should never be filled while inside a vehicle or its trunk, the This is also true for people who mix some gasoline with their diesel fuel in the winter. or rack supporting the unit to be replaced for several seconds. and any charge can be safely Some locations have a strong reason for eliminating these little charges. In my last column, I wrote about static electricity and the need for a bonding cable. Links A build-up of static charge is a potential danger when refuelling aircraft or vehicles. What are the dangers of using static electricity? point where it fails and won't function again. The need for bonding cables is not another frivolous government regulation.
