why is static electricity dangerous when refuelling an aircraft

then charge is transferred If the charge is of sufficiently high potential, it can cause sparking within the aircraft or the origin storage tank. Avoid prolonged breathing of gasoline vapors. VO\UD|. Use gasoline only in open areas that get plenty of fresh air. The surfaces will attract each other, when they have opposing charges (positive and negative). Does Fracking Cause Flaming Water Faucets? This is a special and infrequent operation; the personnel involved, including any flight crew, should be careful to refer to the necessary procedural documentation. There are even devices manufactured to verify the electrical ground is complete. igniting Keep skin moisturized: If your skin is dry, it has a higher likelihood of developing static electricity. It is a much needed safety rule. 0000004060 00000 n Tribo is a Greek word meaning, "to rub". cause an Explosion? 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. Emergency evacuation followed after reports of a landing gear fire. Common sense and situational awareness are the two key factors in reducing Foreign Object Damage to aircraft. a flash fire or small sustained fire with gasoline refueling vapors. Metal is a conductor (1) Electrons / ( negative ) Do not re-enter your vehicle during refueling. You can add humidity to the air to help with this. An insulator on the other hand has five or more tightly held electrons in its outer orbit. 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. 0000001462 00000 n or ESD. Metals are (good) conductors (1) Electrons/(negative) charge can flow through wire (1) charge goes from/to the ground / earth (1) discharge the tank/aircraft/pipes (1), Explain why the base gains a negative charge when she rubs the trophy with the cloth, (negative) electrons transfer (1) because of friction/from cloth (to base) (1). The transfer of hydrocarbon fuels can be dangerous if the proper procedures are not followed. Never siphon gasoline by mouth nor put gasoline in your mouth for any reason. This way the static from your body will be discharged before you remove the nozzle. How can Powder Flowing through a Pipe Turn off your vehicle engine. Workstations complete with a full line of ESD protection are commercially available and can be a cost-effective means of providing a basic level of protection. 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 during refueling operations. On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. %PDF-1.3 % Grounding is unnecessary here because electric charge stays on the outside of the bag where it remains harmless. Passengers boarding or disembarking an aircraft other than via an airbridge should be discouraged from using PEDs. When the right engine also began to run down passing 8000 feet, an emergency was declared and the already-planned straight-in approach was successfully accomplished without any engine thrust. (adsbygoogle = window.adsbygoogle || []).push({}); When charge jumps If the powder is an insulator To understand is to control When fuel tanks on an aircraft are being filled, the aircraft, fuel pipes and tanker are connected by a metal wire to the ground. 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. In a scientific perspective, static happens when theres an imbalance of charges between two objects. Increasing the humidity levels with a humidifier can help mitigate prolonged buildup of static charges in the body. Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. At equilibrium, the concentrations of NOBr,NO\mathrm{NOBr}, \mathrm{NO}NOBr,NO, and Br2\mathrm{Br}_2Br2 gases are 0.0162M0.0162 \mathrm{M}0.0162M, 0.0011M0.0011 M0.0011M, and 0.072M0.072 M0.072M, respectively. 0000009253 00000 n What does a bonding cable do?

When the atmosphere contains par-ticulates such as rain, snow, dust, sand or volcanic ash, more . The aircraft is also connected by a metal cable to the refuelling tanker. 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 . The primary risk is unintended ignition of fuel vapour, which can occur by a single spark. In reality it is the contact or touching of materials mats are also a basic low-cost means of reducing electrical FOD. Do not smoke, light matches or lighters while refueling at the pump or when using gasoline anywhere else. It also appears that PEDs close to or on board modern aircraft can interfere with fuel gauges and some navigation equipment and may cause false fire warnings in cargo/baggage holds. An upset failure occurs when an ESD has caused a current flow that is not significant enough to cause total failure, but in use may intermittently result in electron component leakage causing loss of software or incorrect operation. The fuel itself is an insulator (a hydrocarbon) Physics Quiz Using lotions and moisturizers before getting dressed and throughout the day will help keep static electricity from accumulating on your body. If gasoline spills on the container, make sure that it has evaporated before you place the container in your vehicle.Report spills to the attendant. Procedures for Emergency Passenger Evacuation should take account of the availability or otherwise of airbridge access and in-position ground steps in the selection of exits to be used. The spark can be avoided if the pipe nozzle is made to conduct by connecting an earthing strap to it and so any charge can be safely conducted away. 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 .
