Revision Questions, gcsescience.com Electrostatic Charge Quiz The reason is that the air/fuel ratio is too rich. 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. This is where electrons transfer from a surface to the air. Disable or turn off any auxiliary sources of ignition such as a camper or trailer heater, cooking units, or pilot lights. Porygon Z also gets a very powerful boost to its Tri-Attack during Partly Cloudy weather, which could make up for it being a Normal type move. We documented fires caused by plastic gas cans, nylon windbreakers and, possibly most dangerous of all, human nature. The need to protect sensitive electronic components and circuit boards from ESD during handling, shipping, and assembly helped develop a new class of antistatic packaging materials. ), The student reads an article about the possible build-up of static electricity during the refuelling of an aircraft. Normally, at least one of the flight crew should remain in the flight deck. For example, if you suspend a spark plug 0.1 inches above the fuel level in a container partially full of gasoline and send a charge to the plug to jump the gap, nothing will happen. explosion, Electrons in the outermost orbit may be either firmly or weakly attached. expert on static electricity, but indicates that many of the reports indicate "the refueler became . What does a bonding cable do? 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. 0000001669 00000 n You can add humidity to the air to help with this. 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. When refuelling an airplane, the airplane might be charged due to friction between the plane and the air when the plane was flying, causing electrons to transfer. The worker connects an earth wire to the aircraft before pumping fuel. Almost everyone has had the opportunity to touch something or someone and feel a mild shock. In the event no protective devices are available and a circuit card or other electronic device must be replaced, first touch the grounded box The spark can ignite (set fire to) 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.
