Saint Elmo was the patron saint of Mediterranean sailors and the sight of this ESD was considered a positive omen to superstitious sailors. With Jet A, as with diesel fuel, the vapor pressure of the fuel is low so that the air/fuel ratio at the neck is too lean to burn, sothe chance of a fire is very low. Hazardous products in Class I locations consist of flammable gases, vapors, or liquids. 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. Neither crew nor ATC requested a runway inspection and 12 further aircraft movements occurred before it was closed for inspection and recovery of 14 kg of debris. Wide-cut fuel is considered to be 'involved' when it is being supplied or when it is already present in the aircraft tanks. It may be a temptation to get back in the car for any number of reasons. a spark can jump between the two Do not over-fill or top-off your vehicle tank, which can cause gasoline spillage. Static electricity in the wrong environments, however, may be dangerous. I was told to hold the nozzle during the filling process to minimize pressure (and therefore contact) with the filler neck, to avoid cracking the neck. Most important, motorists should not get back into their vehicles during refueling. Keeping your skin hydrated is one way to reduce the effects of static shock. Exposing the spark to volatile gasoline may create an unexpected combustion. Why is static electricity dangerous when Refuelling an aircraft?

But at some point the component Static electricity can range from an annoyance to a danger to a useful tool. 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. 2 Why is static electricity dangerous when Refuelling an aircraft? The charge will flow through your body causing an electric shock. 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. Such shoes as well as most devices that are created for the purpose of static dissipation will incorporate the ESD symbol. Why should there be any difference in reducing electrical FOD? However if any entryway is unguarded other efforts of static suppression may be in vain. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. Conductors and insulators 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. If someone swallows gasoline, do not induce vomiting. If the circuit is complete and resistance to ground is adequately low the machine will advise. Direct catastrophic failures occur when a component is damaged to the Airport Operators are recommended to prohibit the use of PEDs on the apron area in the vicinity of refuelling operations. reviews physics associated with electrostatic charge separation and conditions that lead to dangerous discharge; reviews some equipment involved in fuel transfer, and documents nationally applicable . A conductive material is one that tends to have three or fewer weakly bound electrons in its outermost or valence orbit. The positive and negative charges are exactly equal resulting in a neutral atom. fuel tank, They must be mixed with air in correct proportions or air/fuel ratios to burn. Electricity is an important part of our lives, but we always have to treat it with respect and care. have resulted in a brief flash fire occurring at the fill point. 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. HS=o0+n Therefore triboelectricity is a form of electricity produced by rubbing. so that there can be no difference in charge between them.
