This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. then charge is transferred Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. 3 Is static electricity dangerous in aircraft operation? In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. What changed? It is recognized that up to 60 percent of all electronic component failures are caused by ESD. conducted away. Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home. Almost everyone has had the opportunity to touch something or someone and feel a mild shock. 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. flammable liquids, On no account should either the fuelling vehicle (including hydrant dispenser) or the aircraft be bonded to a fuel hydrant pit. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. Electrons in the outermost orbit may be either firmly or weakly attached. Index 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. 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. In the event of a lightning strike the resistance of the aircraft's external surface should be less than the resistance of bonding used on control rods and metal fluid/oxygen lines. Contact a doctor or and emergency medical service provider immediately. 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. Wire Craft is Seattle's premier electrical company. How do you get rid of static electricity in your body? The material that looses the electron becomes a positive ion while the material gaining the electron will become negative. 0000007608 00000 n Metal cased equipment will typically provide a cage preventing ESD contamination. In a scientific perspective, static happens when theres an imbalance of charges between two objects. He has been a private pilot since 1985. 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. 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. Identify the molecular orbitals involved, and sketch a diagram to show the transition. Static electricity is produced when the positive and negative charges of an atom are out of balance.

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. You may apply lotion or moisturizer on your . 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. as fuel in pipes (see above). How do we deal with this invisible and silent foe? A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. Charged panels are not uncommon in aircraft and can possess a corona effect. Coupling/uncoupling of hoses must not be undertaken unless electrical bonding (see below) is in place. Electrostatic Charge 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. Allowing a few minutes before removing nozzles when the pumping is complete also helps assure that static electricity has dissipated. There is a large potential difference (voltage) between the metal rods and the metal plates. What is the main danger from static electricity? When you rub a balloon against a carpet of a piece of clothing, it will stick to the wall without any adhesives. 0000009799 00000 n (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). 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. 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.
