Figure 1. 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. Awareness is the true key. 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. g~:-A`qK#P O|{{1*T _{MA}gk MC1a!PqLKTEat5(B)jn?oS{}Wd@JY4pnxv Hxhb1$aF Sparks caused by static electricity are a major source of fires and explosions in many industries. On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home. 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. 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. 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. Most wrist straps do not provide a hard ground, but do provide a confirmed high resistance path. Now an experienced GCSE and A Level Physics and Maths tutor, Ashika helps to grow and improve our Physics resources. The article also states that the aircraft is connected by a metal cable to the ground. Why should there be any difference in reducing electrical FOD? Use gasoline only in open areas that get plenty of fresh air. Index gcsescience.com. ", Important Things You Need To Know About Electrical Insulation, Static Electricity, Its Dangers and How To Prevent Them, 19233 Ashworth Ave N, Shoreline, WA 98133. Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). and charge can be transferred as the fuel flows through Turn off your vehicle engine. Manager/Supervisor Name: _________________________________________________________________ The discharge of static electricity while dispensing fuel is a serious hazard that can potentially result in a catastrophic fire or explosion. In my last column, I wrote about static electricity and the need for a bonding cable. Electricity is an important part of our lives, but we always have to treat it with respect and care. Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. The transfer of charge Tribo is a Greek word meaning, "to rub". 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. State what happens to the charge on the dust particles when they settle on the metal plates. Interesting article. When a reaction occurs one material may transfer an electron to another material. 0000008505 00000 n 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. He has been a private pilot since 1985. This may happen safely by connecting them to the earth with a conductor. 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. 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. However periodic dealings do not eradicate the need for precautions. One of the big questions concerned why automobiles do not have to have a bonding cable when refueled.

They were very professional both times. The killer providing the spark is sometimes . Electrons in the outermost orbit may be either firmly or weakly attached. Suggest why the cup does not become charged. How is static electricity dangerous with regards to Mills? 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. 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 . refuelling. You may apply lotion or moisturizer on your . You can add humidity to the air to help with this. This fuel is very flammable; The friction between the fuel . 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. We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. conducted away. One form of FOD that has been all but overlooked is electrostatic discharge Probably not, but with an understanding of the phenomena and knowledge of protective devices the uncontrolled discharge of static energy can be controlled. Name the kinds of evidence that systematists use in constructing a phylogenetic tree. The surfaces will repel each other, when they have the same charge. gcsescience.com, Home To control the effects of static electricity and for . 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. Wrist straps also counter unwanted static discharge. explosion, A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. particularly with aircraft which are filled at In addition, a cable can connect the pipe to Ive Heard that Hydraulic Fracturing is Linked to Cancer. If the charge is very large, a spark to. Explain why the charge does not build up on the metal plates. Calculate the duration of the flash in seconds. The hairs on your head stand when electrons from a hat transfer to your hair. 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. 0000009799 00000 n We use cookies to ensure that we give you the best experience on our website. During the lightning flash a total charge of 52 C flows. that will greatly reduce the possibility of ESD. They work on the same principle as a high resistance ohmmeter. If you need help assessing the electrical safety of your home, dont hesitate to call us at Wire Craft Electric. The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. Use only the refueling latch provided on the gasoline dispenser nozzle. If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing Crew stations and duties should be clearly defined as should appropriate passenger communications. The result is a ghostly glow visible often in low light conditions. If the charge is very large, a spark to the earth may happen unexpectedly. or ESD. All rights reserved.

Motorists who cannot avoid getting back into the vehicle should always first touch a metal part of the vehicle with a bare hand, such as the door, or some other metal surface, away from the fill point upon exiting the vehicle. Conditions Boosting the Generation of . (Note that the gases need to be expressed as pressure in atm. The driver may be carrying excess electrons, which may create a spark when you touch the fuel pump. If the circuit is complete and resistance to ground is adequately low the machine will advise. 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. \~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 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. 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. fuel tank, They must be mixed with air in correct proportions or air/fuel ratios to burn. An electrostatic air filter is designed to remove dust particles from the air in a room. It is a much needed safety rule. Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. 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. 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. 0000006516 00000 n 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. Fill container no more than 95 percent full to allow for expansion. 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. . [[{>&@}M 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. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. Another danger is static electrical shock. supply / earth /ground Saint Elmo's Fire is the common name for this corona discharge effect.

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. Static electricity along with too much heat can ignite these products. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. As the nozzle (the end) of the pipe is Use gasoline as a motor fuel only. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. 0000007851 00000 n 0000004562 00000 n "Excellent work and workmanship. Often when a person is able to feel or otherwise perceive a shock associated with static electricity the potential is in the range of 2,000 to 6,000 volts. happens 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. Pumping fuel into an aircraft can be dangerous. If the person handling the bag wears insulating gloves or is otherwise not capable of discharging an electrical buildup, then the component may draw a strong electrical spark as it is withdrawn from the protective casing and may be damaged. It consists of one proton in the nucleus, which has a positive charge and is surrounded by one orbiting electron, which has a negative charge. What are Alternatives to Make Fracking Less Impactful? 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. Sign up here. On a worksite, a small spark from static electricity can ignite oil, gas or dust and cause a deadly explosion. The reason is that the air/fuel ratio is too rich. 0000002998 00000 n Workstations complete with a full line of ESD protection are commercially available and can be a cost-effective means of providing a basic level of protection. It should be noted that Fuel Hoses, including so-called conductive hoses, are not suitable substitutes for dedicated clips and bonding wires. vapours and powders in pipes. Whats the Difference Between Wastewater Disposal and Fracking? cars or aircraft. Insulators prevent the electrons from moving and the charge remains static. 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. The worker connects an earth wire to the aircraft before pumping fuel. Passengers boarding or disembarking an aircraft other than via an airbridge should be discouraged from using PEDs. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. When the aircraft charge is great enough, it discharges into the surrounding air. The hydrogen atom is the simplest as well as the lightest. 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. 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. There is a large potential difference (voltage) between the metal rods and the metal plates. A static discharge resulting from as . Our skilled professionals are on standby waiting to address your next electrical concern. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. There is a very similar situation with powders in pipes. ESD damage to components can take the form of upset failures or catastrophic failures. To understand static charges we have to first have a grasp of the atom. In the event no protective devices are available and a circuit card or other electronic device must be replaced, first touch the grounded box High humidity conditions are conducive to dissipation of static charges resulting in reduced effects of ESD. Revision Questions, gcsescience.com If the powder is an insulator 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. Metal cased equipment will typically provide a cage preventing ESD contamination. There is a large potential difference (voltage) between the metal rods and the metal plates. 2 Why is static electricity dangerous when Refuelling an aircraft? How can Powder Flowing through a Pipe Avoid prolonged breathing of gasoline vapors. a very high speed. It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated. 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. 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. Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). 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. Never jam the refueling latch on the nozzle open. It may be a temptation to get back in the car for any number of reasons. If the charge is very large, a spark to the earth may happen unexpectedly. 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. 0000060792 00000 n *eu=D:~#GZZTGQ],GwF\l$22{ GW,J^t0Tm-jcX4u?=63[{LWYtSdOc(I7{rYSis6~m/ $4 endstream endobj 29 0 obj 493 endobj 30 0 obj << /Filter /FlateDecode /Length 29 0 R >> stream ESD protective floor I was taught that they were rubber to prevent a spark from jumping from the nozzle to the fuel tank opening. Todays trucks have metal nozzles. Keep the nozzle in contact A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. conducted away. 0000004039 00000 n When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. 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. Is static electricity useful in lightning? Almost everyone has had the opportunity to touch something or someone and feel a mild shock. Sparks like this can be dangerous, potentially igniting a fire.

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 fuel itself is an insulator (a hydrocarbon) It is recommended that when wide-cut fuel has been used, the next two uplifts of fuel should be treated as though they too were wide-cut. Links The contaminant origin was not identified. In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. Besides environmental control, other precautionary measures can be used The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. 1 What is the main danger from static electricity?
