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. 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. mats are also a basic low-cost means of reducing electrical FOD. very quickly because it has a very 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. Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). s 7^ Ak# endstream endobj 52 0 obj 170 endobj 18 0 obj << /Type /Page /Parent 13 0 R /Resources 19 0 R /Contents [ 28 0 R 30 0 R 32 0 R 34 0 R 36 0 R 40 0 R 42 0 R 44 0 R ] /MediaBox [ 0 0 612 792 ] /CropBox [ 0 0 612 792 ] /Rotate 0 >> endobj 19 0 obj << /ProcSet [ /PDF /Text ] /Font << /TT2 24 0 R /TT4 20 0 R /TT6 21 0 R /TT8 37 0 R >> /ExtGState << /GS1 47 0 R >> /ColorSpace << /Cs6 26 0 R >> >> endobj 20 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 121 /Widths [ 278 0 0 0 0 0 722 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 667 611 0 0 0 0 0 0 0 0 778 0 0 0 667 0 0 0 0 0 0 0 0 0 0 0 0 0 556 0 556 0 556 0 611 0 278 0 0 278 0 611 611 611 0 389 556 333 611 0 0 0 556 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHBP+Arial,Bold /FontDescriptor 22 0 R >> endobj 21 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 150 /Widths [ 250 0 0 0 0 0 0 278 0 333 0 0 250 333 250 278 0 500 500 500 500 0 0 0 0 0 333 0 0 0 0 0 0 722 0 0 722 667 611 778 0 389 0 0 667 944 722 778 611 0 722 556 667 722 722 0 0 0 0 0 0 0 0 500 0 500 556 444 556 444 333 500 556 278 0 556 278 833 556 500 556 556 444 389 333 556 500 722 0 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHDB+TimesNewRoman,Bold /FontDescriptor 25 0 R >> endobj 22 0 obj << /Type /FontDescriptor /Ascent 905 /CapHeight 0 /Descent -211 /Flags 32 /FontBBox [ -628 -376 2000 1010 ] /FontName /LPDHBP+Arial,Bold /ItalicAngle 0 /StemV 133 /FontFile2 45 0 R >> endobj 23 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 656 /Descent -216 /Flags 34 /FontBBox [ -568 -307 2000 1007 ] /FontName /LPDHBN+TimesNewRoman /ItalicAngle 0 /StemV 94 /XHeight 0 /FontFile2 46 0 R >> endobj 24 0 obj << /Type /Font /Subtype /TrueType /FirstChar 32 /LastChar 150 /Widths [ 250 0 408 0 0 0 0 0 333 333 0 0 250 333 250 278 500 500 500 500 0 500 0 0 500 0 278 0 0 0 0 0 0 722 667 667 722 611 556 722 722 333 0 0 611 889 722 722 556 0 667 556 611 722 722 944 0 0 611 0 0 0 0 0 0 444 500 444 500 444 333 500 500 278 0 500 278 778 500 500 500 500 333 389 278 500 500 722 500 500 444 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 500 ] /Encoding /WinAnsiEncoding /BaseFont /LPDHBN+TimesNewRoman /FontDescriptor 23 0 R >> endobj 25 0 obj << /Type /FontDescriptor /Ascent 891 /CapHeight 656 /Descent -216 /Flags 34 /FontBBox [ -558 -307 2000 1026 ] /FontName /LPDHDB+TimesNewRoman,Bold /ItalicAngle 0 /StemV 160 /FontFile2 50 0 R >> endobj 26 0 obj [ /ICCBased 48 0 R ] endobj 27 0 obj 424 endobj 28 0 obj << /Filter /FlateDecode /Length 27 0 R >> stream Dangers of electrostatics All charged objects can be discharged by being earthed. When filling a portable container, manually control the nozzle valve throughout the filling process. Sign up here. 0000007851 00000 n The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. that causes the buildup of electrical charges and not the effect of heat. 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 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. If the circuit is complete and resistance to ground is adequately low the machine will advise. cars or aircraft. 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. 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. Another danger is static electrical shock. Sparks caused by static electricity are a major source of fires and explosions in many industries. 1 What is the main danger from static electricity? The fuel itself is an insulator (a hydrocarbon) But at some point the component 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. The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. For their own safety, keep passengers out of the aircraft while fueling is in progress. Remove gasoline-soaked clothing immediately. 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. Keep the nozzle in contact If you need help assessing the electrical safety of your home, dont hesitate to call us at Wire Craft Electric. Technicians can test to make sure of proper grounding. and any charge can be safely Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. "Excellent work and workmanship. causes a spark. This could cause burns or even stop your heart. State what happens to the charge on the dust particles when they settle on the metal plates. Direct catastrophic failures occur when a component is damaged to the Keeping your skin hydrated is one way to reduce the effects of static shock. Why is static electricity dangerous when Refuelling an aircraft? When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. Contact a doctor or and emergency medical service provider immediately. 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. It should be noted that Fuel Hoses, including so-called conductive hoses, are not suitable substitutes for dedicated clips and bonding wires. Copyright 2015 gcsescience.com. The way to avoid an explosion 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. 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; GCSE Physics. 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. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. Josh is now my go to Electrician! When to ground a fire truck for static electricity? a spark can jump between the two Research has shown that several actions could reduce the risk of fires caused by static electricity at gas stations. These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. 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. 2023 Endeavor Business Media, LLC. 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. Encased equipment should always have protective covers placed over the electric connectors and care should be exercised to avoid direct contact with electrical pins. 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. Does Fracking Cause Flaming Water Faucets? large surface area and This may happen safely by connecting them to the earth with a conductor. This can cause a serious Crew stations and duties should be clearly defined as should appropriate passenger communications. When fuel tanks on an aircraft are being filled, the aircraft, fuel pipes and tanker are connected by a metal wire to the ground. How can Fuel Flowing On 16 April 2014, a pre-flight concern about whether a Boeing 777-200ER about to depart Singapore had been overfuelled was resolved by a manual check but an en-route fuel system alert led to close monitoring of the fuel system. cause an Explosion? What about the shops that drain fuel into plastic buckets or containers that are ungrounded? will have to be removed from the bag. 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 the easiest type of ESD damage to find since it usually can be detected during testing. If you continue to use this site we will assume that you are happy with it. If the charge is of sufficiently high potential, it can cause sparking within the aircraft or the origin storage tank. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. If the charge is very large, a spark to. Index igniting 0000001441 00000 n if the pipe nozzle A fan blows dusty air past several metal rods and metal plates. One form of FOD that has been all but overlooked is electrostatic discharge A person could die from an electric shock. 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).

ESD protective floor 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. 0000006537 00000 n Static electricity in the wrong environments, however, may be dangerous. Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. Containers should never be filled while inside a vehicle or its trunk, the bed of a pickup truck or the floor of a trailer. 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. Kgf@"rHE+@FW.s{D>4 u o This results in a change in the state of charge. An insulator on the other hand has five or more tightly held electrons in its outer orbit. A build-up of static charge is a potential danger when refuelling aircraft or vehicles. Figure 1. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. 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. Emergency evacuation followed after reports of a landing gear fire. 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. Todays trucks have metal nozzles. Allowing a few minutes before removing nozzles when the pumping is complete also helps assure that static electricity has dissipated. Ive Heard that Hydraulic Fracturing is Linked to Cancer. Notify the station attendant immediately. then charge is transferred It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. Do not smoke, light matches or lighters while refueling at the pump or when using gasoline anywhere else. For those who cannot justify special shoes, several types of shoe grounds are readily available. this can cause an explosion. 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 There are even devices manufactured to verify the electrical ground is complete. Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. What can you put on a tree stump to make it rot? Sparks like this can be dangerous, potentially igniting a fire. gcsescience.com, Home 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. (a) Write a balanced equation for the reaction. 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. In reality it is the contact or touching of materials Only store gasoline in approved containers as required by federal or state authorities. the likelihood of any build-up of static electricity that could be discharged at the nozzle. 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. the fuel. supply / earth /ground conducted away. Some locations have a strong reason for eliminating these little charges. In rare circumstances, these static related incidents Using lotions and moisturizers before getting dressed and throughout the day will help keep static electricity from accumulating on your body. 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. 0000007608 00000 n Static electricity is caused by an atom having too many or too few electrons (e-). and charge can be transferred as the fuel flows through Connecting a static. Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. 8 When to ground a fire truck for static electricity?

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. Back to the basics: For a spark to start a fire or explosion, one must have fuel, air and an ignition source. 0000006516 00000 n A static discharge resulting from as . 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. This is where electrons transfer from a surface to the air. conducted away. 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 metal cup does not become charged when she rubs the trophy. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. fire? This fuel is very flammable; The friction between the fuel . The reason is that the air/fuel ratio is too rich. Explain why this greatly reduces the chance of a spark. 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. 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. . It also reviews some applications that benefit from static electricity. In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. 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. 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.
