Can formation of electrostatic charges be realistically eliminated? 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. But liquid fuels like avgas and Jet A do not burn. 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. 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. A build-up of static charge is a potential danger when refuelling aircraft or vehicles. 2023 Flyer Media, Inc. All rights reserved. as fuel in pipes (see above). When to ground a fire truck for static electricity? 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. Agricultural businesses, such as grain storehouses, accumulate dust which is easily ignited by a spark. and so any charge can be safely 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. 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. supply / earth /ground Calculate the duration of the flash in seconds. The hairs on your head stand when electrons from a hat transfer to your hair. Allowing a few minutes before removing nozzles when the pumping is complete also helps assure that static electricity has dissipated. Wire Craft is Seattle's premier electrical company. Wrist straps also counter unwanted static discharge. 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 . This article explains how static electricity could be unexpectedly generated and how to adopt safe designs and practices in order to avoid incidents. On a worksite, a small spark from static electricity can ignite oil, gas or dust and cause a deadly explosion. It also appears that PEDs close to or on board modern aircraft can interfere with fuel gauges and some navigation equipment and may cause false fire warnings in cargo/baggage holds. The killer providing the spark is sometimes . On no account should either the fuelling vehicle (including hydrant dispenser) or the aircraft be bonded to a fuel hydrant pit.

This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. The issues are much the same whether the fuel source is a tanker/bowser or a fuel hydrant system. If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing 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. a very high speed. Gasoline can be harmful or fatal if swallowed. Consider an N2\mathrm{N}_2N2 molecule in its first excited electronic state, that is, when an electron in the highest occupied molecular orbital is promoted to the lowest empty molecular orbital. Relative humidity of the air along with atmospheric contaminates will have an effect on the ability of a material to build up a static charge as well as the tendency to dissipate one. Most important, motorists should not get back into their vehicles during refueling. A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. This results in a change in the state of charge. Copyright SKYbrary Aviation Safety, 2021-2023. Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. 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. It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated. 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. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . cars or aircraft. All rights reserved. Electrostatic Charge The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. Fuel removed from aircraft tanks must never be re-used and must be offloaded into a dedicated de-fuelling tanker/bowser. Sparks like this can be dangerous, potentially igniting a fire.

When filling a portable container, manually control the nozzle valve throughout the filling process. Does Fracking Cause Flaming Water Faucets? 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. 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. GCSE Physics. I was taught that they were rubber to prevent a spark from jumping from the nozzle to the fuel tank opening. 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. Never jam the refueling latch on the nozzle open. 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. Conductors and insulators Another danger is static electrical shock. Exposing the spark to volatile gasoline may create an unexpected combustion. Do not re-enter your vehicle during refueling. 0000058037 00000 n Porygon Z also gets a very powerful boost to its Tri-Attack during Partly Cloudy weather, which could make up for it being a Normal type move. in the same The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. 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. Electrical bonding must be used to eliminate this hazard. Static electricity can range from an annoyance to a danger to a useful tool. Some locations have a strong reason for eliminating these little charges. How do you get rid of static electricity in your body? 0000002786 00000 n gcsescience.com. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize The refueling driveway surface should be made of conductive materialconcrete is generally conductive, while asphalt is not. The conductivity of the fuel should be examined and considered. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. Use only the refueling latch provided on the gasoline dispenser nozzle. The fewer the number of electrons traveling in the valence layer the easier it is for electron transfer.

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. This is the easiest type of ESD damage to find since it usually can be detected during testing. This is where electrons transfer from a surface to the air. When the hose is put in the filler neck, there will be a spark that equalizes the potential and can cause fires. 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. Only store gasoline in approved containers as required by federal or state authorities. through a Pipe cause an Explosion? Conditions Boosting the Generation of . (Note that the gases need to be expressed as pressure in atm. Why is Porygon-Z good? An earthing strap connects the pipe to the ground (the Earth). Direct catastrophic failures occur when a component is damaged to the Wide-cut fuel is considered to be 'involved' when it is being supplied or when it is already present in the aircraft tanks. 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. What is the main danger from static electricity? Encased equipment should always have protective covers placed over the electric connectors and care should be exercised to avoid direct contact with electrical pins. The surfaces will attract each other, when they have opposing charges (positive and negative). Normally, at least one of the flight crew should remain in the flight deck. A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. 0000001441 00000 n Use an earthing strap between the pipe and the earth Repair shops that deal with electronic components at the repair bench level on a daily basis may have more protective devices in place than a facility that only replaces black boxes. 5 Why does my body create so much static? 0000007851 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.

Figure 1. Fill a portable container slowly to decrease the chance of static electricity buildup and minimize spilling or splattering. Emergency evacuation followed after reports of a landing gear fire. 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. 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. An electrostatic air filter is designed to remove dust particles from the air in a room. They were very professional both times. The contaminant origin was not identified. Remove gasoline-soaked clothing immediately. Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. and charge can be transferred as the fuel flows through Back to the basics: For a spark to start a fire or explosion, one must have fuel, air and an ignition source. 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. An earthing strap connects the pipe to the ground particularly with aircraft which are filled at When insulating materials are rubbed together, electrons are knocked off one of them and onto the other. 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. 0000008505 00000 n Foreign Object Damage (FOD) is something that has been drilled into the minds of aviation personnel. 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 need for bonding cables is not another frivolous government regulation. 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. 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. 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. Like other means of ESD protection their function should be verified and not taken for granted. 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. The surfaces will repel each other, when they have the same charge. He has been a private pilot since 1985. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. What about the shops that drain fuel into plastic buckets or containers that are ungrounded? gcsescience.com Awareness and precaution key The test is accomplished by placing the grounded shoe on a metal plate that is connected to the tester while touching an exposed contact with a finger. 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 Whats the Difference Between Wastewater Disposal and Fracking?

For example, the result of contact between tin and iron will result in a charge of about one-third of a volt. While hazards for fires may be obvious with flammable chemicals, industries where there is a lot of dust, like flour mills, can also be at risk for explosions due to electrostatic sparks. 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. | Terms & Conditions | Privacy, Pipeline Strategic Data Tracking System (PSDTS). Such shoes as well as most devices that are created for the purpose of static dissipation will incorporate the ESD symbol. 52 = 2600 x time transposition time = 52 / 2600 (1) evaluation 0.02 (s). During the lightning flash a total charge of 52 C flows. particularly with aircraft which are filled at a very high speed. Now an experienced GCSE and A Level Physics and Maths tutor, Ashika helps to grow and improve our Physics resources. 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. A contact potential will occur almost anytime two solid objects make contact. We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. 0000006516 00000 n 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. 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. 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. GCSE Chemistry large surface area and 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. The hydrogen atom is the simplest as well as the lightest. This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. If you wish to contribute or participate in the discussions about articles you are invited to join SKYbrary as a registered user. the pipe. Privacy Policy. 2.4.4 Uses & Dangers of Static Electricity.

Fuel running through the pipes can provide the friction needed to create a static charge. 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. Explain why this greatly reduces the chance of a spark. It is dangerous when you touch something with a large electric charge on it. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. 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. conducted away. a pipe if In my last column, I wrote about static electricity and the need for a bonding cable. This is a form of ESD. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. this can cause an explosion. Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. 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. 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. Does Hydraulic Fracturing Cause Earthquakes? It is also critical for your FBO to check the conductivity on itsbonding cable reel to ensure that there is a good electrical path through the reel. Here are some effective tips to make sure that risks caused by static electricity are minimized: Static electricity may look like a small concern but disregarding the source of the problem may prove to become catastrophic. A spark can ignite a powder Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. How Much Water Does Hydraulic Fracturing Use? fire? Electricity is an important part of our lives, but we always have to treat it with respect and care. 7 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). Damage to components. Explain why the charge does not build up on the metal plates. There is a risk that a PED (personal electronic device) may create or induce a spark of sufficient intensity to ignite fuel vapour released during fuelling but it is extremely remote under normal circumstances. 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. 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.
