But at some point the component To control the effects of static electricity and for . However, many jets use a lot of fuel, so that a significant electrical potential can still be built up and jump a large gap, which can have enough fuel vapor to be explosive. ", 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. Disable or turn off any auxiliary sources of ignition such as a camper or trailer heater, cooking units, or pilot lights. Todays trucks have metal nozzles. Contact a doctor or and emergency medical service provider immediately. 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. On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. 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. Conductors, on the other hand, cannot become charged, as the electrons can move through them. 0000004562 00000 n Likewise, if you position the plug several feet above the fuel level and send a spark, nothing will happen because the air/fuel ratio is too lean. 2.4.4 Uses & Dangers of Static Electricity. 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. g~:-A`qK#P O|{{1*T _{MA}gk MC1a!PqLKTEat5(B)jn?oS{}Wd@JY4pnxv Hxhb1$aF At equilibrium, the concentrations of NOBr,NO\mathrm{NOBr}, \mathrm{NO}NOBr,NO, and Br2\mathrm{Br}_2Br2 gases are 0.0162M0.0162 \mathrm{M}0.0162M, 0.0011M0.0011 M0.0011M, and 0.072M0.072 M0.072M, respectively. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. /|zz";|0Bl+$GIk!Sv2w A build-up of static charge is a potential danger when refuelling aircraft or vehicles. The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. 0000058037 00000 n Damage to components. This results in a change in the state of charge. 0000058115 00000 n A static discharge resulting from as . A powder can burn A person could die from an electric shock. 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. refuelling. Keep the nozzle in contact Gasoline can be harmful or fatal if swallowed. 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. In my last column, I wrote about static electricity and the need for a bonding cable. Explain why the dust particles are attracted to the plates 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. In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. is the same as above. How can Fuel Flowing Containers should never be filled while inside a vehicle or its trunk, the Revision Questions, gcsescience.com 0000008526 00000 n Static electricity is often referred to as "triboelectricity." Index 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. 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. Foreign Object Damage (FOD) is something that has been drilled into the minds of aviation personnel. 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. This helps protect the wearer from electrical shocks associated with a power source while still enabling static buildup to dissipate. Ive Heard that Hydraulic Fracturing is Linked to Cancer. 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. 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 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. Is static electricity useful in lightning? Wire Craft is Seattle's premier electrical company. [[{>&@}M Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. An earthing strap connects the pipe to the ground (the Earth). A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. 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. Static electricity is produced when the positive and negative charges of an atom are out of balance. 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. If the circuit is complete and resistance to ground is adequately low the machine will advise. This fuel is very flammable; The friction between the fuel . The hairs on your head stand when electrons from a hat transfer to your hair. Pumping fuel into an aircraft can be dangerous. and charge can be transferred as the fuel flows through 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. Our skilled professionals are on standby waiting to address your next electrical concern. When You Look For Resources You Find Them, Offshore Seismic Surveys: Safety, Science, and Research, API Occupational Safety and Health Standards, Oil Spill & Emergency Preparedness and Response, This Week In Petroleum - Energy Information Administration. All rights reserved. Electrostatic Charge Quiz 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. If you continue to use this site we will assume that you are happy with it. On no account should either the fuelling vehicle (including hydrant dispenser) or the aircraft be bonded to a fuel hydrant pit. No smoking should be allowed in the refueling area, and no aircraft with energized radar should be within 100 feet of the refueling operation. Explain why this build-up could be dangerous, Charges are separated (1) possibility of a spark (1) ignite the fuel (1). Electrons in the outermost orbit may be either firmly or weakly attached. A spark can ignite a powder If you wish to contribute or participate in the discussions about articles you are invited to join SKYbrary as a registered user. Agricultural businesses, such as grain storehouses, accumulate dust which is easily ignited by a spark. The reason is that the air/fuel ratio is too rich. How do we deal with this invisible and silent foe? 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. 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 How Much Water Does Hydraulic Fracturing Use? 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. Keep skin moisturized: If your skin is dry, it has a higher likelihood of developing static electricity. 1 What is the main danger from static electricity? happens A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. (1), Chapter 33: Electric Fields and Potential ID:, Fundamentals of Engineering Economic Analysis, David Besanko, Mark Shanley, Scott Schaefer, Practice IP & Internet Questions - BLAW Modul. Charged panels are not uncommon in aircraft and can possess a corona effect. causes a spark. Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). The surfaces will repel each other, when they have the same charge. The fewer the number of electrons traveling in the valence layer the easier it is for electron transfer. 0000002245 00000 n Conditions Boosting the Generation of . Turn off your vehicle engine. There is a large potential difference (voltage) between the metal rods and the metal plates. This is a form of ESD. They were very professional both times. Give one reason why earthing reduces the risk of fire. Insulators prevent the electrons from moving and the charge remains static. Whats the Difference Between Wastewater Disposal and Fracking? 0000008505 00000 n Tribo is a Greek word meaning, "to rub". 0000005154 00000 n mats are also a basic low-cost means of reducing electrical FOD. ), If asked to explain a use, think carefully about the forces exerted due to static electricity and what they will do. Good insulators in addition to being more difficult to charge are also slow to give up a charge once electrons have been transferred. Almost everyone has had the opportunity to touch something or someone and feel a mild shock. 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. Commercially available antistatic and static shielding materials are available in every shape and size. as fuel in pipes (see above). If the charge is very large, a spark to the earth may happen unexpectedly. 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. ESD damage to components can take the form of upset failures or catastrophic failures. 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. The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft. This is where electrons transfer from a surface to the air. This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. This could cause burns or even stop your heart. } '+.$wY .

Electrostatic Charge 0000006537 00000 n Kgf@"rHE+@FW.s{D>4 u o 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. Use an earthing strap between the pipe and the earth 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). 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. Does Fracking Cause Flaming Water Faucets? 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. 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 resulting explosions are lethal. Catastrophic failures occur in two forms, direct and latent. ", "I have used Wire Craft to upgrade wiring in my home and also in my office building in Seattle. Why should there be any difference in reducing electrical FOD? 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 . ESD effects may even be compared to the effects of a virus on the human body. fire? the pipe is also an insulator. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. 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. 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. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . 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. Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. Fill a portable container slowly to decrease the chance of static electricity buildup and minimize spilling or splattering. 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. Passengers boarding or disembarking an aircraft other than via an airbridge should be discouraged from using PEDs. 0000007608 00000 n Name the kinds of evidence that systematists use in constructing a phylogenetic tree. bed of a pickup truck or the floor of a trailer. To understand static charges we have to first have a grasp of the atom. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. 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. close to the Hazardous products in Class I locations consist of flammable gases, vapors, or liquids.

Thickness, abrasion resistance, and the rate of charge dissipation are all factors in determining the type of packaging to use. 0000023255 00000 n This way the static from your body will be discharged before you remove the nozzle. particularly with aircraft which are filled at Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. 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.). We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. 5 Why does my body create so much static? 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. However periodic dealings do not eradicate the need for precautions. The transfer of charge A build-up of static charge is a potential danger when refuelling aircraft or vehicles. The article also states that the aircraft is connected by a metal cable to the ground. Saint Elmo's Fire is the common name for this corona discharge effect. How Many Jobs Has the Oil and Natural Gas Industry Created? . The aircraft is also connected by a metal cable to the refuelling tanker. 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 fuel. 2.4.4 Uses & Dangers of Static Electricity. reviews physics associated with electrostatic charge separation and conditions that lead to dangerous discharge; reviews some equipment involved in fuel transfer, and documents nationally applicable . In addition, a cable can connect the pipe to To understand is to control How long does it take sunlight to reach Earth? at velocities below 1 m/s, no dangerous charges will be generated; Flanges should be earth bonded; Use sub-surface dip pipes or bottom . 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. 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. There is a very similar situation with powders in pipes. How do planes get rid of static electricity? 0000060792 00000 n Awareness is the true key. Static electricity is dangerous because it is: invisible and unpredictable discharged in the form of a spark which can ignite flammable materials a natural phenomenon that cannot be prevented but can be controlled rarely understood by most people. It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. Static electricity is caused by an atom having too many or too few electrons (e-). Use gasoline as a motor fuel only. just like it can ignite a flammable liquid or vapour. 0000007195 00000 n 8 When to ground a fire truck for static electricity?
