Keep gasoline away from your eyes and skin; it may cause irritation. How to Market Your Business with Webinars. Copyright 2021 - API. The principal hazard of static electricity is a spark discharge that could ignite a fire or even cause an explosion. 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. and charge can be transferred as the fuel flows through Only store gasoline in approved containers as required by federal or state authorities. 0000007608 00000 n The spark can ignite (set fire to) If the powder is an insulator HS=o0+n 0000008505 00000 n What does a bonding cable do? There is a very similar situation with powders in pipes. (The vapor pressure of auto fuel has decreased in recent years and is closer to that of 100LL). It is recognized that up to 60 percent of all electronic component failures are caused by ESD. The charge will flow through your body causing an electric shock. Tribo is a Greek word meaning, "to rub". 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 friction strips electrons from the atmosphere and causes them to build up on the skin of the aircraft. 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. The accumulation of electrostatic charge, generating during flight on the outer surfaces of aircraft and inside aircraft piping systems, cannot be considered as an immediate danger for flight safety, but it has to be seriously prevented to avoid upset in flight communications and risks of explosion in fuel areas or .

Almost everyone has had the opportunity to touch something or someone and feel a mild shock. The kerosene fuel used by turbine engine aircraft has a higherflash/ignition pointthan the aviation gasoline used by piston engine aircraft but there are still potential hazards. It may be a temptation to get back in the car for any number of reasons. the charge was neutralised (1) by a transfer/flow of electrons. This article explains how static electricity could be unexpectedly generated and how to adopt safe designs and practices in order to avoid incidents. 6 What are the dangers of using static electricity? What can you put on a tree stump to make it rot? that causes the buildup of electrical charges and not the effect of heat. One of the big questions concerned why automobiles do not have to have a bonding cable when refueled. ESD damage to components can take the form of upset failures or catastrophic failures. This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. 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. gcsescience.com The Investigation found that engine failure had followed Super Absorbent Polymer (SAP) contamination of some of the fuel nozzle valves which caused them to malfunction leading to Low Pressure Turbine (LPT) mechanical damage. This effect can often be demonstrated by observing someone attempting to clean the acrylic windshield of an aircraft shortly after a flight. Use only the refueling latch provided on the gasoline dispenser nozzle. Fill container no more than 95 percent full to allow for expansion. Key developments in polymers, especially conductive polyethylene and sophisticated laminates with very thin metallized films, have made successful transportation of sensitive equipment a reality. The fuel itself is an insulator (a hydrocarbon) It is recommended that the circumstances under which such an event might occur during refuelling should be carefully considered and mitigated.
