Static electricity in the wrong environments, however, may be dangerous. 0000003226 00000 n Can a small spark from static electricity cause an explosion? 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. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. Catastrophic failures occur in two forms, direct and latent. Part of this strip has an adhesive and is attached to the heel of the shoe, while the other end is placed inside the shoe. 5 Why does my body create so much static? flammable liquids, Explain what happens to the charge on the metal tower as a result of the lightning flash. 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. 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. Technicians involved in the daily repair of electronics may choose to wear shoes that are specially designed to continuously dissipate any static buildup occurring on the wearer. particularly with aircraft which are filled at a very high speed. Todays trucks have metal nozzles. This is a form of ESD. For their own safety, keep passengers out of the aircraft while fueling is in progress. 0000004583 00000 n 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. 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. 3 Is static electricity dangerous in aircraft operation? Physics Quiz On a piston aircraft, the vapor pressure of the fuel is less than that of auto gas and the filler neck is more out in the open where the wind can easily raise the air/fuel ration at the filler neck into the explosive range. Keep indoor air humid: Dry air increases the risk of static electricity buildup in your home.

If the charge is very large, a spark to the earth may happen unexpectedly. The way to avoid an explosion "Excellent work and workmanship. 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. 0000002998 00000 n Many electronic workshops include certain sensitive areas where the environment is closely monitored and controlled including the relative humidity in the air. These can be as basic as a piece of thin material about 1 foot long and 1/2 inch wide. Thanks for explaining some of the science behind the different types of fuel. Keep your face away from the nozzle or container opening. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. gcsescience.com Interesting article. (a) Write a balanced equation for the reaction. Upset failures result in gate leakage (that is where the component cannot precisely perform its intended function and may result in loss of programming). ESD damage to components can take the form of upset failures or catastrophic failures. conducted away. Links is made to conduct by connecting an It may be a one in a million chance but there is a danger that static electricity may ignite the gasoline vapours during refueling at a petrol station. Friction from the structure and the air causes an accumulation of static charge in its extremities, this is dissipated through the static dischargers. Hb```9 abkBHr2}I'> rY#:::\:::jAbk iE V20b!Lj@s(T k$%WYH]_33 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. Electrical bonding must be used to eliminate this hazard. This will reduce any potential shock. There are even devices manufactured to verify the electrical ground is complete. 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. This is the easiest type of ESD damage to find since it usually can be detected during testing. refuelling. Therefore triboelectricity is a form of electricity produced by rubbing. The resulting explosions are lethal. This friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. 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. Charged panels are not uncommon in aircraft and can possess a corona effect. There is a very similar situation with powders in pipes. then charge is transferred As the nozzle (the end) of the pipe is 6 What are the dangers of using static electricity? Electrostatic Charge Quiz An earthing strap connects the pipe to the ground (the Earth). 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. Index brought . 0000004039 00000 n 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. 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. Put your vehicle in park and/or set the emergency brake. A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit.
