Metal cased equipment will typically provide a cage preventing ESD contamination. Figure 1. When a divergent discrepancy between the two independent fuel remaining sources became apparent, an uneventful precautionary air turnback was made and overfuelling subsequently confirmed. 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. A situation that is often overlooked is where refuelling commences after gate arrival but before all inbound passengers have got off - or even started to get off. Use gasoline as a motor fuel only. Give one reason why earthing reduces the risk of fire. The charge will flow through your body causing an electric shock. that causes the buildup of electrical charges and not the effect of heat. Static electricity is caused by an atom having too many or too few electrons (e-). 0000001669 00000 n Contact a doctor or and emergency medical service provider immediately. Electrostatic Charge Quiz 0000007830 00000 n at velocities below 1 m/s, no dangerous charges will be generated; Flanges should be earth bonded; Use sub-surface dip pipes or bottom . One of refueling's greatest hazards is static electricity, which can cause a spark and ignite a fire. Care must be taken to avoid sparks when putting fuel in ", Important Things You Need To Know About Electrical Insulation, Static Electricity, Its Dangers and How To Prevent Them, 19233 Ashworth Ave N, Shoreline, WA 98133. Sparks like this can be dangerous, potentially igniting a fire. (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). But at some point the component This is a form of ESD. between the pipe and the powder A build-up of static charge is a potential danger when refuelling aeroplanes; Fuel runs through pipes at a fast rate. Electricity is an important part of our lives, but we always have to treat it with respect and care. What changed? If the motorist then returns to the vehicle fill pipe during refueling, the static may discharge at the fill point, causing However, many jets use a lot of fuel, so that a significant electrical potential can still be built up and jump a large gap, which can have enough fuel vapor to be explosive. This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. When an object builds up too much electrical charge with no means of release, you may get electrocuted as you touch the charged object. Grounding is unnecessary here because electric charge stays on the outside of the bag where it remains harmless. Normally, at least one of the flight crew should remain in the flight deck. as fuel in pipes (see above). It is dangerous when you touch something with a large electric charge on it.

A humidifier may do the trick. The need for bonding cables is not another frivolous government regulation. 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. Saint Elmo's Fire is the common name for this corona discharge effect. Explain how these cables reduce the dangers when refuelling the aircraft. However periodic dealings do not eradicate the need for precautions. During the lightning flash a total charge of 52 C flows. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. The result is a ghostly glow visible often in low light conditions. When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . 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. When the aeroplanes are charged after travelling in the air and contact with air particle the potential difference between it and the Earth is very high so electrons try to jump from the craft to. Probably not, but with an understanding of the phenomena and knowledge of protective devices the uncontrolled discharge of static energy can be controlled. The surfaces will attract each other, when they have opposing charges (positive and negative). Is static electricity useful in lightning? A sufficient quantity of fuel vapour to create a high risk of ignition may result from spillage arising from procedural errors, leaks, aircraft tank venting or failure of pressurized fuel lines or their couplings. ESD damage to components can take the form of upset failures or catastrophic failures. 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. You may apply lotion or moisturizer on your . One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. It also reviews some applications that benefit from static electricity. Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. Using lotions and moisturizers before getting dressed and throughout the day will help keep static electricity from accumulating on your body. just like it can ignite a flammable liquid or vapour. 2 Why is static electricity dangerous when Refuelling an aircraft? .

Direct catastrophic failures occur when a component is damaged to the Why is static electricity dangerous when Refuelling an aircraft? Why is static electricity dangerous when Refuelling an aircraft? Does Fracking Cause Flaming Water Faucets? All Rights Reserved. Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. Aircraft electrical racks also have a very low resistance path to the aircraft structure. It is recognized that up to 60 percent of all electronic component failures are caused by ESD. What are the Claims of Anti-Fracking Activists? in the same Revision Questions, gcsescience.com 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. and charge can be transferred as the fuel flows through Keep skin moisturized: If your skin is dry, it has a higher likelihood of developing static electricity. The conductivity of the fuel should be examined and considered. then charge is transferred 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. (adsbygoogle = window.adsbygoogle || []).push({}); When charge jumps Gasoline can be harmful or fatal if swallowed. 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. In addition, a cable can connect the pipe to the fuel tank, In the course of our research we learned that a buildup of static electricity can be generated by many different sources. Turn off your vehicle engine. Containers should never be filled while inside a vehicle or its trunk, the 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. In my last column, I wrote about static electricity and the need for a bonding cable. 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. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. The reason is that the air/fuel ratio is too rich. The best way to address this is to keep the relative humidity above 30%. When to ground a fire truck for static electricity? But liquid fuels like avgas and Jet A do not burn. Our skilled professionals are on standby waiting to address your next electrical concern.
