Explain why this greatly reduces the chance of a spark. 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 . 0000003226 00000 n IBO was not involved in the production of, and does not endorse, the resources created by Save My Exams. Sign up here. The charge will flow through your body causing an electric shock. Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. If the powder is an insulator Static Electricity Can Cause Fires! if the pipe nozzle Never store gasoline in glass or any other unapproved container. If someone swallows gasoline, do not induce vomiting. or ESD. fire? Awareness is the true key. The kerosene fuel used by turbine engine aircraft has a higherflash/ignition pointthan the aviation gasoline used by piston engine aircraft but there are still potential hazards. 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. It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. brought There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. Care must be taken to avoid sparks when putting fuel in 3 Is static electricity dangerous in aircraft operation? that will greatly reduce the possibility of ESD. The spark can be avoided 0000001180 00000 n On no account should either the fuelling vehicle (including hydrant dispenser) or the aircraft be bonded to a fuel hydrant pit. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. Ive seen a couple of those result in static electricity fires that did tremendous damage. and any charge can be safely Metals are (good) conductors (1) Electrons/(negative) charge can flow through wire (1) charge goes from/to the ground / earth (1) discharge the tank/aircraft/pipes (1), Explain why the base gains a negative charge when she rubs the trophy with the cloth, (negative) electrons transfer (1) because of friction/from cloth (to base) (1). 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. How is Groundwater Protected During Hydraulic Fracturing? 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. A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. bed of a pickup truck or the floor of a trailer. 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. What can be done about gas station fires caused by static electricity? 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. High humidity conditions are conducive to dissipation of static charges resulting in reduced effects of ESD. 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. This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated. charge moves (through the plates/ wire) (1) Towards the voltage Fuel running through the pipes can provide the friction needed to create a static charge. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. 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. Copyright SKYbrary Aviation Safety, 2021-2023. Tribo is a Greek word meaning, "to rub". Containers should never be filled while inside a vehicle or its trunk, the All rights reserved. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. 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. Is static electricity useful in lightning? A static discharge resulting from as . Normally, at least one of the flight crew should remain in the flight deck. 0000007608 00000 n Commercially available antistatic and static shielding materials are available in every shape and size. .

The reason for using a bonding strap during refueling is that when an electrically, non-conductive fluid like Jet A or 100LL is transferred, these liquids build up static electricity that can arc and cause a fire if not dissipated. 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. in the same Wire Craft is Seattle's premier electrical company. 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. GCSE Chemistry Many electronic workshops include certain sensitive areas where the environment is closely monitored and controlled including the relative humidity in the air. Keeping your skin hydrated is one way to reduce the effects of static shock. Metal is a conductor (1) Electrons / ( negative ) 2023 Flyer Media, Inc. All rights reserved. The transfer of charge The average current is 2600 A. 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. a flash fire or small sustained fire with gasoline refueling vapors. will have to be removed from the bag. Avoid prolonged breathing of gasoline vapors. Like other means of ESD protection their function should be verified and not taken for granted. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. 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. The fuel itself is an insulator (a hydrocarbon) A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. The reason is that the air/fuel ratio is too rich. 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. the fuel tank, have resulted in a brief flash fire occurring at the fill point. the pipe. Why is static electricity dangerous when Refuelling an aircraft? How Many Jobs Has the Oil and Natural Gas Industry Created? Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). 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. When the aircraft charge is great enough, it discharges into the surrounding air. then charge is transferred Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. Conductors and insulators Sparks like this can be dangerous, potentially igniting a fire. There is a very similar situation with powders in pipes. In reality it is the contact or touching of materials Why should there be any difference in reducing electrical FOD? A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Direct catastrophic failures occur when a component is damaged to the Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. He's completed a number of projects and there are several more in the planing phase. Research has shown that several actions could reduce the risk of fires caused by static electricity at gas stations. Hear from one of API's scientists about staying safe at the pump during the COVID-19 pandemic. The contaminant origin was not identified. across an air gap it Download PDF Test Yourself. 0000002998 00000 n When fuel tanks on an aircraft are being filled, the aircraft, fuel pipes and tanker are connected by a metal wire to the ground. 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. 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. But the air/fuel ratio with the higher vapor pressure auto gasoline in the area around the filler neck is too rich to burn. A powder can burn Can formation of electrostatic charges be realistically eliminated? Is static electricity dangerous in aircraft operation? 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. Keep the nozzle in contact 52 = 2600 x time transposition time = 52 / 2600 (1) evaluation 0.02 (s). He has been a private pilot since 1985. For their own safety, keep passengers out of the aircraft while fueling is in progress. 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 is dangerous when you touch something with a large electric charge on it. 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. Give one reason why earthing reduces the risk of fire. gcsescience.com, Home 2.4.4 Uses & Dangers of Static Electricity. These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. Use gasoline only in open areas that get plenty of fresh air. This will reduce any potential shock. Disable or turn off any auxiliary sources of ignition such as a camper or trailer heater, cooking units, or pilot lights. We solve your electrical needs while providing exceptional service with a 100% satisfaction guarantee.

Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. Copyright 2021 - API. Agricultural businesses, such as grain storehouses, accumulate dust which is easily ignited by a spark. Use an earthing strap between the pipe and the earth A person could die from an electric shock. The aircraft is also connected by a metal cable to the refuelling tanker. Back to the basics: For a spark to start a fire or explosion, one must have fuel, air and an ignition source. 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. The driver may be carrying excess electrons, which may create a spark when you touch the fuel pump. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. fuel tank, When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. Consumers can take steps to minimize these and other potential fueling hazards by following safe refueling procedures all year long. refuelling. 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. Only store gasoline in approved containers as required by federal or state authorities. Interesting article. This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. 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. 6 What are the dangers of using static electricity? Todays trucks have metal nozzles. Name the kinds of evidence that systematists use in constructing a phylogenetic tree. In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle.

Whats the Difference Between Wastewater Disposal and Fracking? 0000058115 00000 n Besides environmental control, other precautionary measures can be used Wide-cut fuel is considered to be 'involved' when it is being supplied or when it is already present in the aircraft tanks. As we learned before, the drier the air or your skin, the higher the potential of being zapped. explosion, When insulating materials are rubbed together, electrons are knocked off one of them and onto the other. Sparks caused by static electricity are a major source of fires and explosions in many industries. 0000060792 00000 n 0000004583 00000 n 0000074721 00000 n 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. . (b) Calculate KKK for the reaction at 25C25^{\circ} \mathrm{C}25C. point where it fails and won't function again. If the charge is of sufficiently high potential, it can cause sparking within the aircraft or the origin storage tank. What changed? The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. Using lotions and moisturizers before getting dressed and throughout the day will help keep static electricity from accumulating on your body. 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. . This way the static from your body will be discharged before you remove the nozzle. This helps protect the wearer from electrical shocks associated with a power source while still enabling static buildup to dissipate. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. All Rights Reserved. Explain why the dust particles are attracted to the plates The conductivity of the fuel should be examined and considered. Electrical bonding must be used to eliminate this hazard.
