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. 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. have resulted in a brief flash fire occurring at the fill point. Keep skin moisturized: If your skin is dry, it has a higher likelihood of developing static electricity. Consumers can take steps to minimize these and other potential fueling hazards by following safe refueling procedures all year long. 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. A powder can burn flammable liquids, a spark can jump between the two 7 Can a small spark from static electricity cause an explosion? ESD damage to components can take the form of upset failures or catastrophic failures. Aircraft electrical racks also have a very low resistance path to the aircraft structure. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. The article also states that the aircraft is connected by a metal cable to the ground. Explain why this greatly reduces the chance of a spark. There is a large potential difference (voltage) between the metal rods and the metal plates. Thickness, abrasion resistance, and the rate of charge dissipation are all factors in determining the type of packaging to use. Keep your face away from the nozzle or container opening. "Excellent work and workmanship. Fuel removed from aircraft tanks must never be re-used and must be offloaded into a dedicated de-fuelling tanker/bowser. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. 5 Why does my body create so much static? supply / earth /ground 0000005175 00000 n across an air gap it Static electricity along with too much heat can ignite these products. Keeping your skin hydrated is one way to reduce the effects of static shock. An electrostatic air filter is designed to remove dust particles from the air in a room. They were very professional both times. Saint Elmo's Fire is the common name for this corona discharge effect. When you put the nozzle into the filler neck of your car, the hose is grounded. The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. The charge density in the fuel and the possibility of sparks inside the tanks are not affected by bonding. In addition, a cable can connect the pipe to 0000004000 00000 n Sparks caused by static electricity are a major source of fires and explosions in many industries. Containers should never be filled while inside a vehicle or its trunk, the Privacy Policy. 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. 2 Why is static electricity dangerous when Refuelling an aircraft? close to the ESD protective floor 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. 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. 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.

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? and so any charge can be safely When a reaction occurs one material may transfer an electron to another material. 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. Place cap tightly on the container after filling - do not use containers that do not seal properly. because there is friction between the fuel and Sparks like this can be dangerous, potentially igniting a fire. Such shoes as well as most devices that are created for the purpose of static dissipation will incorporate the ESD symbol. These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. The best way to address this is to keep the relative humidity above 30%. 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. Therefore triboelectricity is a form of electricity produced by rubbing. Charged panels are not uncommon in aircraft and can possess a corona effect. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. All rights reserved. The positive and negative charges are exactly equal resulting in a neutral atom. 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 are Alternatives to Make Fracking Less Impactful? 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. This is where electrons transfer from a surface to the air. 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. Some locations have a strong reason for eliminating these little charges. 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. But the average fill-up takes only two minutes, and staying outside the vehicle will greatly minimize 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. Never store gasoline in glass or any other unapproved container. 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. particularly with aircraft which are filled at a very high speed. The transfer of charge 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. Keep the nozzle in contact On a worksite, a small spark from static electricity can ignite oil, gas or dust and cause a deadly explosion. Explain why the dust particles are attracted to the plates The resulting explosions are lethal. Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. 0000008526 00000 n The best approach is precaution resulting in prevention by sterilization. They must be mixed with air in correct proportions or air/fuel ratios to burn. Gasoline can be harmful or fatal if swallowed. or ESD. The worker connects an earth wire to the aircraft before pumping fuel. Conductors, on the other hand, cannot become charged, as the electrons can move through them. 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.
