On 13 April 2010, a Cathay Pacific Airbus A330-300 en route from Surabaya to Hong Kong experienced difficulty in controlling engine thrust. When dispensing gasoline into a container, use only an approved portable container and place it on the ground to avoid a possible static electricity ignition of fuel vapors. Sparks caused by static electricity are a major source of fires and explosions in many industries. bed of a pickup truck or the floor of a trailer. GCSE Physics. Fuel movement during refuelling or defuelling may lead to the a static charge building up in the fuel. 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. Static electricity is created when objects with different electrical properties come into contact, and negatively charged electrons from one substance are transferred to the other. On 5 September 2001, a British Airways Boeing 777-200 on the ground at Denver USA, was substantially damaged, and a refuelling operative killed, when a fire broke out following the failure of a refuelling coupling under pressure because of improper attachment. Electrons in the outermost orbit may be either firmly or weakly attached. a spark can jump between the two 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. 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. 0000008505 00000 n so that there can be no difference in charge between them. the charge was neutralised (1) by a transfer/flow of electrons. Why is fracking for natural gas important? If the charge is very large, a spark to the earth may happen unexpectedly. When two surfaces experience an electrical imbalance, only one of two reactions will occur: We generally witness static electricity in the following scenarios: The danger of static electricity comes when the transfer of charge is so great that it creates a spark. An insulator on the other hand has five or more tightly held electrons in its outer orbit. 0000001087 00000 n We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. To understand static charges we have to first have a grasp of the atom. 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. 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 conducted away. Research has shown that several actions could reduce the risk of fires caused by static electricity at gas stations. Index Good insulators in addition to being more difficult to charge are also slow to give up a charge once electrons have been transferred. Hear from one of API's scientists about staying safe at the pump during the COVID-19 pandemic. Aircraft electrical racks also have a very low resistance path to the aircraft structure. However periodic dealings do not eradicate the need for precautions. Bonding cables should connect the installation delivering the fuel with the aircraft or installation receiving the fuel.
