why is static electricity dangerous when refuelling an aircraft
Electrical bonding in conjunction with static dischargers is used on aircraft to minimize the potential for stray charged panels which in addition could result in radio interference. Besides environmental control, other precautionary measures can be used When the aircraft charge is great enough, it discharges into the surrounding air. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. They were very professional both times. 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. Is static electricity useful in lightning? One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. 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. 1 What is the main danger from static electricity? Static electricity in the wrong environments, however, may be dangerous. if the pipe nozzle For their own safety, keep passengers out of the aircraft while fueling is in progress. Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. 2.4.4 Uses & Dangers of Static Electricity. The transfer of charge This voltage is generally quite low but varies with material types. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. Is that True? 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 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. The hairs on your head stand when electrons from a hat transfer to your hair. 0000058037 00000 n When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . Kgf@"rHE+@FW.s{D>4 u o Have you experienced getting jolted by a spark of electricity when you touched a door knob or hand rail? Ashika graduated with a first-class Physics degree from Manchester University and, having worked as a software engineer, focused on Physics education, creating engaging content to help students across all levels. the fuel tank, 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. 0000005853 00000 n When a reaction occurs one material may transfer an electron to another material. 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. Gasoline can be harmful or fatal if swallowed. have resulted in a brief flash fire occurring at the fill point. Put your vehicle in park and/or set the emergency brake. As the nozzle (the end) of the pipe is 0000004000 00000 n Pumping fuel into an aircraft can be dangerous. 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.

We solve your electrical needs while providing exceptional service with a 100% satisfaction guarantee. Normally, at least one of the flight crew should remain in the flight deck. because there is friction between the fuel and bed of a pickup truck or the floor of a trailer. Is static electricity useful in lightning? All Rights Reserved. with the rim of the container opening while refueling. Use gasoline as a motor fuel only. Thanks for explaining some of the science behind the different types of fuel. 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. 0000008505 00000 n Metal cased equipment will typically provide a cage preventing ESD contamination. Technicians can test to make sure of proper grounding.

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. Most important, motorists should not get back into their vehicles during refueling. The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. A person could die from an electric shock. 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. or rack supporting the unit to be replaced for several seconds. *R X P0#NtoC 0h!a%%1^K rV"3\$3LvgNP D$PF0$Hv 9$56ef>mD=qu@%xNo5osEQC:#;RFVL};KZ7r9]#9sGkk^5=B,x%vx^c\byr#~cWY%{ What can be done about gas station fires caused by static electricity? the pipe is also an insulator. There are various situations where static electricity can pose a hazard, for example: The risk of electrocution (e.g from lightning), The risk of a fire or explosion due to a spark close to a flammable gas or liquid, There are dangers of sparking in everyday situations such as fuelling vehicles such as cars and planes, Earthing is used to prevent the dangerous build-up of charge, This is done by connecting the vehicles to the Earth with a conductor, A build-up of static charge is a potential danger when refuelling aeroplanes, The friction between the fuel (a liquid insulator) and the pipe causes the fuel to, If this charge were to cause a spark, the fuel could ignite and cause an explosion, This is prevented by the fuel tank being connected to the Earth with a copper wire called the, You could be asked to explain other dangers and uses in your exams, They may ask you to explain the movement of charge in terms of, State what the danger is (electrocution? b8+ '!"3w=f94s!A=JRal4n;sC*vk(9/+0NG$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; Download PDF Test Yourself. nLxOZ1Tl^/uk%#Hxpfp(pmubxlsM`` Dpmb/dh >O2%|(;oAnTok)CwJi2ZeV:\m1lLafSXnp"Pb".L]4!\2Tqs3I"MGn"qRal `DRJTL]sNnT\f)T0bZ=EwU0 z_FO endstream endobj 1 0 obj << /Type /Page /Parent 77 0 R /Resources 2 0 R /Contents 3 0 R /MediaBox [ 0 0 378 540 ] /CropBox [ 0 0 378 540 ] /Rotate 0 >> endobj 2 0 obj << /ProcSet [ /PDF /Text ] /Font << /F1 61 0 R /F2 90 0 R /F5 62 0 R >> /ExtGState << /GS1 93 0 R >> /ColorSpace << /Cs9 89 0 R >> >> endobj 3 0 obj << /Length 2472 /Filter /FlateDecode >> stream To control the effects of static electricity and for . When transporting gasoline in a portable container make sure it is secured against tipping and sliding, and never leave it in direct sunlight or in the trunk of a car. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. The driver may be carrying excess electrons, which may create a spark when you touch the fuel pump. The aircraft is also connected by a metal cable to the refuelling tanker. Index If the charge is very large, a spark to the earth may happen unexpectedly. 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. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. 0000005154 00000 n 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. Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. 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. } '+.$wY . G=Po9dByh|q[6luvSe*Fn!yc[ T"%*Lp{v*dO Cu! 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. 2023 Endeavor Business Media, LLC. Ben Visser is an aviation fuels and lubricants expert who spent 33 years with Shell Oil. 0000005874 00000 n explosion, particularly with aircraft which are filled at a very high speed. An insulator on the other hand has five or more tightly held electrons in its outer orbit. Saint Elmo's Fire is the common name for this corona discharge effect. Sign up here. is the same as above. A powder can burn In a scientific perspective, static happens when theres an imbalance of charges between two objects. Never allow children under licensed driving age to operate the pump. Turn off your vehicle engine. a very high speed. Static electricity is often referred to as "triboelectricity." 0000005175 00000 n 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. 7 Explain why this build-up could be dangerous, Charges are separated (1) possibility of a spark (1) ignite the fuel (1). 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. All rights reserved. close to the Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. 0000007830 00000 n One of the most common occurrences of static electricity dangers is refueling a vehicle. Electrostatic Charge Tribo is a Greek word meaning, "to rub". 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. charge moves (through the plates/ wire) (1) Towards the voltage The need for bonding cables is not another frivolous government regulation. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. cause an Explosion? However periodic dealings do not eradicate the need for precautions. An electrostatic air filter is designed to remove dust particles from the air in a room. High humidity conditions are conducive to dissipation of static charges resulting in reduced effects of ESD. We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. A key function of equipment earthing is to provide a controlled method to prevent the build up of static electricity, thus reducing the risk of electrical discharge in potentially hazardous environments. 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.). 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. We use cookies to ensure that we give you the best experience on our website. Suggest why the cup does not become charged. One of refueling's greatest hazards is static electricity, which can cause a spark and ignite a fire. particularly with aircraft which are filled at conducted away. | Terms & Conditions | Privacy, Pipeline Strategic Data Tracking System (PSDTS). Static Electricity Can Cause Fires! Keep the nozzle in contact This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. Whats the Difference Between Wastewater Disposal and Fracking? 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. 0000006516 00000 n What is the main danger from static electricity? Todays trucks have metal nozzles. 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 Never store gasoline in glass or any other unapproved container. point where it fails and won't function again. Care must be taken to avoid sparks when putting fuel in Exposing the spark to volatile gasoline may create an unexpected combustion. a flash fire or small sustained fire with gasoline refueling vapors.

Conductors and insulators Explain why the dust particles are attracted to the plates It is not currently known whether such a failure would be of sufficient magnitude to ignite a fuel/air mixture but the possibility exists. Ive Heard that Hydraulic Fracturing is Linked to Cancer. Conductors, on the other hand, cannot become charged, as the electrons can move through them. 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. then charge is transferred How do planes get rid of static electricity? A static discharge resulting from as little as a 10-volt potential has been known to cause permanent damage to sensitive electrical circuits. It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. 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. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. Back to the basics: For a spark to start a fire or explosion, one must have fuel, air and an ignition source. This could cause burns or even stop your heart. This is where electrons transfer from a surface to the air. Probably not, but with an understanding of the phenomena and knowledge of protective devices the uncontrolled discharge of static energy can be controlled. 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. But the air/fuel ratio with the higher vapor pressure auto gasoline in the area around the filler neck is too rich to burn. cars or aircraft. Fill a portable container slowly to decrease the chance of static electricity buildup and minimize spilling or splattering. ", "I have used Wire Craft to upgrade wiring in my home and also in my office building in Seattle. A particular concern is the proliferation of below-specification mobile telephone batteries that have the potential to fail dangerously. In reality it is the contact or touching of materials As we learned before, the drier the air or your skin, the higher the potential of being zapped. In the event no protective devices are available and a circuit card or other electronic device must be replaced, first touch the grounded box 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. 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. 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. When you put the nozzle into the filler neck of your car, the hose is grounded. Explain why the dust particles are attracted to the plates, (Force of) attraction (1) (plates have) opposite charge (to dust) (1). How is static electricity dangerous with regards to Mills? 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. 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 can cause an explosion. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. To understand static charges we have to first have a grasp of the atom. (Note that the gases need to be expressed as pressure in atm. 0000001462 00000 n Damage to components. Awareness and precaution key supply / earth /ground 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. g~:-A`qK#P O|{{1*T _{MA}gk MC1a!PqLKTEat5(B)jn?oS{}Wd@JY4pnxv Hxhb1$aF This is the easiest type of ESD damage to find since it usually can be detected during testing. This is a form of ESD. 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. a pipe if 0000001180 00000 n 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. , `` I have used Wire Craft to upgrade wiring in my home and also my.
