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. 0000007195 00000 n
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. If someone swallows gasoline, do not induce vomiting. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. GCSE Physics. this can cause an explosion. ), If asked to explain a use, think carefully about the forces exerted due to static electricity and what they will do. 0000004060 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. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. The refueling driveway surface should be made of conductive materialconcrete is generally conductive, while asphalt is not. 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. Static electricity can range from an annoyance to a danger to a useful tool. How Many Jobs Has the Oil and Natural Gas Industry Created? 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. %PDF-1.3

The way to avoid an explosion
Fuel running through the pipes can provide the friction needed to create a static charge. When insulating materials are rubbed together, electrons are knocked off one of them and onto the other. This way the static from your body will be discharged before you remove 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. 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. 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. In reality it is the contact or touching of materials The need for bonding cables is not another frivolous government regulation.
Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. Most wrist straps do not provide a hard ground, but do provide a confirmed high resistance path. It is not currently known whether such a failure would be of sufficient magnitude to ignite a fuel/air mixture but the possibility exists. Put your vehicle in park and/or set the emergency brake.

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. 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. Explain why this greatly reduces the chance of a spark. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. 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 contaminant origin was not identified. 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. Can formation of electrostatic charges be realistically eliminated? Motorists who cannot avoid getting back into the vehicle should always first touch a metal part of the vehicle with a bare hand, such as the door, or some other metal surface, away from the fill point upon exiting the vehicle. 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. Saint Elmo's Fire is the common name for this corona discharge effect. To understand static charges we have to first have a grasp of the atom. gcsescience.com. 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. But liquid fuels like avgas and Jet A do not burn. 7
Keep your face away from the nozzle or container opening. The surfaces will repel each other, when they have the same charge.

A fan blows dusty air past several metal rods and metal plates. Thanks for explaining some of the science behind the different types of 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. ", "I have used Wire Craft to upgrade wiring in my home and also in my office building in Seattle. Electricity / 2.4 Static Electricity / 2.4.4 Uses & Dangers of Static Electricity. The hairs on your head stand when electrons from a hat transfer to your hair. Avoid prolonged breathing of gasoline vapors. (a) Write a balanced equation for the reaction. Electricity is an important part of our lives, but we always have to treat it with respect and care. Direct catastrophic failures occur when a component is damaged to the Notify the station attendant immediately. Youmust move the spark source closer to the fuel until you find a combustible air/fuel ratio, and then it will burn. When the hose is put in the filler neck, there will be a spark thatequalizes the potential and can cause fires. Containers should never be filled while inside a vehicle or its trunk, the Place cap tightly on the container after filling - do not use containers that do not seal properly. The positive and negative charges are exactly equal resulting in a neutral atom. that will greatly reduce the possibility of ESD. point where it fails and won't function again. 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. causes a spark. 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.

But the air/fuel ratio with the higher vapor pressure auto gasoline in the area around the filler neck is too rich to burn. and so any charge can be safely
Use only the refueling latch provided on the gasoline dispenser nozzle. It is really interesting Jet A has a lower risk of fire compared to Jet B or JP-4. Conductors and insulators For those who cannot justify special shoes, several types of shoe grounds are readily available. Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel. Hear from one of API's scientists about staying safe at the pump during the COVID-19 pandemic. 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. Most important, motorists should not get back into their vehicles during refueling. When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. 5 Why does my body create so much static? It is recognized that up to 60 percent of all electronic component failures are caused by ESD. (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). Connecting a static. 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. This may happen safely by connecting them to the earth with a conductor. What can you put on a tree stump to make it rot? brought

Ben Visser is an aviation fuels and lubricants expert who spent 33 years with Shell Oil. Never use gasoline to wash your hands or as a cleaning solvent. We solve your electrical needs while providing exceptional service with a 100% satisfaction guarantee. Static electricity is caused by an atom having too many or too few electrons (e-). One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). 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. 0000060792 00000 n
However, the use of static dissipater additives in fuel can contribute materially to reducing the risk involved. . Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. 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. 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. This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. [[{>&@}M Why is Porygon-Z good? How Much Water Does Hydraulic Fracturing Use? A build-up of static charge is a potential danger when refuelling aircraft or vehicles. 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. Keeping your skin hydrated is one way to reduce the effects of static shock. Tribo is a Greek word meaning, "to rub". Aircraft electrical racks also have a very low resistance path to the aircraft structure. Copyright 2021 - API. 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. 2023 Endeavor Business Media, LLC. Is static electricity useful in lightning? way
particularly with aircraft which are filled at a very high speed. This happens when a polythene strip is rubbed with a duster, the electrons move from the duster to the strip. 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 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. Fill container no more than 95 percent full to allow for expansion. In my last column, I wrote about static electricity and the need for a bonding cable. supply / earth /ground There must be a cable to link to designated points or to clean unpainted metal surfaces on the chosen airframe. Index
Keep skin moisturized: If your skin is dry, it has a higher likelihood of developing static electricity. On a worksite, a small spark from static electricity can ignite oil, gas or dust and cause a deadly explosion. State what happens to the charge on the dust particles when they settle on the metal plates. HS=o0+n 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. Suggest why the cup does not become charged. 0000001180 00000 n
