Besides environmental control, other precautionary measures can be used 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. If the charge is very large, a spark to the earth may happen unexpectedly. 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. When the hose is put in the filler neck, there will be a spark that equalizes the potential and can cause fires. To control the effects of static electricity and for . a very high speed. Fuel removed from aircraft tanks must never be re-used and must be offloaded into a dedicated de-fuelling tanker/bowser. Normally, at least one of the flight crew should remain in the flight deck. 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. Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. 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. 0000004060 00000 n then charge is transferred The spark can be avoided During the lightning flash a total charge of 52 C flows.

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. The fuel itself is an insulator (a hydrocarbon) It is recognized that up to 60 percent of all electronic component failures are caused by ESD. 0000005154 00000 n 0000001840 00000 n Why should there be any difference in reducing electrical FOD? 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.). 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. 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? 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. Figure 1. the charge was neutralised (1) by a transfer/flow of electrons. Another danger is static electrical shock. Gasoline can be harmful or fatal if swallowed. 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. Care must be taken to avoid sparks when putting fuel in Static Electricity Can Cause Fires! Calculate the duration of the flash in seconds. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. Wide-cut fuel is considered to be 'involved' when it is being supplied or when it is already present in the aircraft tanks. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. Why is fracking for natural gas important? 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. There is a large potential difference (voltage) between the metal rods and the metal plates. If the circuit is complete and resistance to ground is adequately low the machine will advise. In the unlikely event a static-caused fire occurs when refueling, leave the nozzle in the fill pipe and back away from the vehicle. 0000023255 00000 n . Catastrophic failures occur in two forms, direct and latent. Insulators prevent the electrons from moving and the charge remains static. Todays trucks have metal nozzles.
