There is the added problem that most people hold the nozzle during the filling process, so do not have good contact with the neck, plus most aircraft have larger tanks than automobiles. Re-fuelling should not take place during active electrical storms/thunderstormsin the immediate vicinity of the airport. Saint Elmo's Fire is the common name for this corona discharge effect. Awareness and precaution key Use gasoline as a motor fuel only. between the pipe and the powder Hear from one of API's scientists about staying safe at the pump during the COVID-19 pandemic. A key function of equipment earthing is to provide a controlled method to prevent the build up of static electricity, thus reducing the risk of electrical discharge in potentially hazardous environments. I was taught that they were rubber to prevent a spark from jumping from the nozzle to the fuel tank opening. What are the dangers of using static electricity? Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. Use an earthing strap between the pipe and the earth Aircraft electrical racks also have a very low resistance path to the aircraft structure. so that there can be no difference in charge between them. Static electricity is caused by an atom having too many or too few electrons (e-). This can cause a serious This is also true for people who mix some gasoline with their diesel fuel in the winter. Static electricity is produced when the positive and negative charges of an atom are out of balance. Besides environmental control, other precautionary measures can be used In addition, during the pumping process, static electricity is built up, which can also cause a spark if the hose does not have good contact with the neck or the ground in the hose itself is not good. Is that True? ESD protective floor This is a form of ESD. Name the kinds of evidence that systematists use in constructing a phylogenetic tree. The issues are much the same whether the fuel source is a tanker/bowser or a fuel hydrant system. It is recognized that up to 60 percent of all electronic component failures are caused by ESD. Aircraft refuelling and de-fuelling are accompanied by attendant hazards which must be managed sufficiently for their mitigation to acceptable levels. What Does EPA Say About Water Contamination? Index The driver may be carrying excess electrons, which may create a spark when you touch the fuel pump. 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. 0000058037 00000 n A static discharge resulting from as . gcsescience.com or ESD. When insulating materials are rubbed together, electrons are knocked off one of them and onto the other. IBO was not involved in the production of, and does not endorse, the resources created by Save My Exams. Ive Heard that Hydraulic Fracturing is Linked to Cancer. Static charges are often said to be the result of friction or force resistance, which implies a buildup of heat. Contact a doctor or and emergency medical service provider immediately. There are contact points in these reels that can corrode and result in a loss of electrical conductivity. 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. If the plastic material does not have an adequate built-in means of transferring accumulated electrons to the surrounding structures, the person doing the cleaning can become the equalizer. 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.

Back to the basics: For a spark to start a fire or explosion, one must have fuel, air and an ignition source. 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. Figure 1. Salt water contamination of the hydrant fuel system at Surabaya after alterations during airport construction work was found to have led to the appearance of a polymer contaminant in uplifted fuel. Accumulation of a surface static charge may occur on either an aircraft or its fuelling vehicle under certain conditions. Keep the nozzle in contact But liquid fuels like avgas and Jet A do not burn. Keeping your skin hydrated is one way to reduce the effects of static shock. Never jam the refueling latch on the nozzle open. Tribo is a Greek word meaning, "to rub". 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. A build-up of static electricity can be caused by re-entering a vehicle during fueling, particularly in cool or cold and dry weather. To understand is to control 0000007851 00000 n The problem is that because of static charge buildup, there can be a difference in electrical potential between the refueler and the aircraft.
