Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home. Therefore triboelectricity is a form of electricity produced by rubbing. Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. Static electricity along with too much heat can ignite these products. supply / earth /ground happens How can Fuel Flowing Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. Copyright 2021 - API. Hb```9 abkBHr2}I'> rY#:::\:::jAbk iE V20b!Lj@s(T k$%WYH]_33 They must be mixed with air in correct proportions or air/fuel ratios to burn. 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? The reason is that the air/fuel ratio is too rich. Keep the nozzle in contact Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. Most important, motorists should not get back into their vehicles during refueling. Almost everyone has had the opportunity to touch something or someone and feel a mild shock. Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. 0000008505 00000 n conducted away. 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. Is static electricity useful in lightning? 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. Physics Quiz 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. 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. cars or aircraft. The killer providing the spark is sometimes . Metal is a conductor (1) Electrons / ( negative ) Fill container no more than 95 percent full to allow for expansion. 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. 2023 Flyer Media, Inc. All rights reserved. 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. 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 principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. as fuel in pipes (see above). A fan blows dusty air past several metal rods and metal plates. 5 Why does my body create so much static? 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. The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. 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. earthing strap to it I received numerous replies so I thought I would add some additional information. Todays trucks have metal nozzles. Static electricity is often referred to as "triboelectricity." All Rights Reserved. But liquid fuels like avgas and Jet A do not burn. Can a small spark from static electricity cause an explosion? Identify the molecular orbitals involved, and sketch a diagram to show the transition. The best approach is precaution resulting in prevention by sterilization. Name the kinds of evidence that systematists use in constructing a phylogenetic tree. the pipe. (Note that the gases need to be expressed as pressure in atm. How do planes get rid of static electricity? The way to avoid an explosion 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. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. Ive seen a couple of those result in static electricity fires that did tremendous damage. For their own safety, keep passengers out of the aircraft while fueling is in progress. This results in a change in the state of charge. There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . 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. The average current is 2600 A. fire? When dispensing gasoline into a container, use only an approved portable container and place it on the ground to avoid a possible static electricity ignition of fuel vapors. How do we deal with this invisible and silent foe? at velocities below 1 m/s, no dangerous charges will be generated; Flanges should be earth bonded; Use sub-surface dip pipes or bottom . 52 = 2600 x time transposition time = 52 / 2600 (1) evaluation 0.02 (s). But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize 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$WQ. Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. mats are also a basic low-cost means of reducing electrical FOD. Never use gasoline to wash your hands or as a cleaning solvent. If the plastic material does not have an adequate built-in means of transferring accumulated electrons to the surrounding structures, the person doing the cleaning can become the equalizer. 0000001087 00000 n One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. IBO was not involved in the production of, and does not endorse, the resources created by Save My Exams. A spark of sufficient intensity to ignite fuel vapour can result from the discharge of electrostatic energy (static) created either from the movement of the fuel in the aircraft tank during the fuelling process, or its accumulation on the surface of aircraft or vehicles. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. One of the most common occurrences of static electricity dangers is refueling a vehicle. This may happen safely by connecting them to the earth with a conductor. } '+.$wY .

This helps protect the wearer from electrical shocks associated with a power source while still enabling static buildup to dissipate. 7 In my last column, I wrote about static electricity and the need for a bonding cable. The resulting explosions are lethal. He's completed a number of projects and there are several more in the planing phase. Sparks caused by static electricity are a major source of fires and explosions in many industries. and charge can be transferred as the fuel flows through The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. 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. Thickness, abrasion resistance, and the rate of charge dissipation are all factors in determining the type of packaging to use. How long does it take sunlight to reach Earth? ), If asked to explain a use, think carefully about the forces exerted due to static electricity and what they will do. Mixtures of wide-cut and kerosene turbine fuels can result in the air-fuel mixture in the tank being in the combustible range at common ambient temperatures during fuelling. because there is friction between the fuel and particularly with aircraft which are filled at Why is static electricity dangerous when Refuelling an aircraft? The aircraft is also connected by a metal cable to the refuelling tanker. He has been a private pilot since 1985. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Use only the refueling latch provided on the gasoline dispenser nozzle. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. 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. The metal cup does not become charged when she rubs the trophy. It is a much needed safety rule. The fuel itself is an insulator (a hydrocarbon) 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. Electrons in the outermost orbit may be either firmly or weakly attached. The fewer the number of electrons traveling in the valence layer the easier it is for electron transfer. 0000003226 00000 n 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. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. To understand is to control 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. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. In addition, a cable can connect the pipe to On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. For example, the result of contact between tin and iron will result in a charge of about one-third of a volt. Josh is now my go to Electrician! 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. 0000004562 00000 n An electrostatic air filter is designed to remove dust particles from the air in a room. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. 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 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.). However periodic dealings do not eradicate the need for precautions. Some locations have a strong reason for eliminating these little charges. in the same Never allow children under licensed driving age to operate the pump. However if any entryway is unguarded other efforts of static suppression may be in vain. During the lightning flash a total charge of 52 C flows. Avoid prolonged breathing of gasoline vapors. This article explains how static electricity could be unexpectedly generated and how to adopt safe designs and practices in order to avoid incidents. It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated. We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. 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. 6 What are the dangers of using static electricity? Direct catastrophic failures occur when a component is damaged to the Only store gasoline in approved containers as required by federal or state authorities. Links Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. Emergency evacuation followed after reports of a landing gear fire. . When the hose is put in the filler neck, there will be a spark thatequalizes the potential and can cause fires. 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. explosion, 0000009253 00000 n The result is a ghostly glow visible often in low light conditions. 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 surfaces will repel each other, when they have the same charge. Sparks like this can be dangerous, potentially igniting a fire. Conditions Boosting the Generation of . 1.1.3 Core Practical: Investigating Motion, 1.2.8 Core Practical: Investigating Force & Extension, 2.1 Current, Potential Difference & Resistance, 2.2 Components in Series & Parallel Circuits, 2.4.2 Core Practical: Investigating Charging by Friction, 3.2.3 Core Practical: Investigating Refraction, 3.2.5 Core Practical: Investigating Snell's law, 3.3.1 Core Practical: Investigating the Speed of Sound, 3.3.3 Core Practical: Using an Oscilloscope, 4.1.5 Core Practical: Investigating Thermal Energy, 5.1.2 Core Practical: Determining Density, 5.2.3 Core Practical: Investigating Changes of State, 5.2.5 Core Practical: Investigating Specific Heat Capacity, 6.1.4 Core Practical: Investigating Magnetic Fields, 7.1.4 Core Practical: 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. Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. just like it can ignite a flammable liquid or vapour. 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. A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. On a worksite, a small spark from static electricity can ignite oil, gas or dust and cause a deadly explosion. 0000005175 00000 n On no account should either the fuelling vehicle (including hydrant dispenser) or the aircraft be bonded to a fuel hydrant pit. If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing very quickly because it has a very large surface area and Explain why the charge does not build up on the metal plates. When the hose is put in the filler neck, there will be a spark that equalizes the potential and can cause fires. Another danger is static electrical shock. . Interesting article. Saint Elmo's Fire is the common name for this corona discharge effect. this can cause an explosion. 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. 1 What is the main danger from static electricity? A build-up of static charge is a potential danger when refuelling aircraft or vehicles. 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. Privacy Policy. ), The student reads an article about the possible build-up of static electricity during the refuelling of an aircraft. Keeping your skin hydrated is one way to reduce the effects of static shock. *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 When you rub a balloon against a carpet of a piece of clothing, it will stick to the wall without any adhesives. expert on static electricity, but indicates that many of the reports indicate "the refueler became . Conductors and insulators Connecting a static. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. Never jam the refueling latch on the nozzle open. The spark can be avoided 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. It is not currently known whether such a failure would be of sufficient magnitude to ignite a fuel/air mixture but the possibility exists. 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. Wrist straps also counter unwanted static discharge. 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. Contact a doctor or and emergency medical service provider immediately. This can cause a serious 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. They were very professional both times. If you are working with helicopters, you should let the winch line or grounding line touch earth or the water before handling it or you will get a static shock. How is Groundwater Protected During Hydraulic Fracturing? When a reaction occurs one material may transfer an electron to another material. A static discharge resulting from as . Exposing the spark to volatile gasoline may create an unexpected combustion. 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 addition, a cable can connect the pipe to the fuel tank, 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. Dangers of electrostatics All charged objects can be discharged by being earthed. 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. 4 How do planes get rid of static electricity? Fuel running through the pipes can provide the friction needed to create a static charge. charge moves (through the plates/ wire) (1) Towards the voltage way a spark can jump between the two 0000058115 00000 n This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. 3 Is static electricity dangerous in aircraft operation? Ben Visser is an aviation fuels and lubricants expert who spent 33 years with Shell Oil. A humidifier may do the trick. 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.
