WebSince propagating brush discharge only occurs in insulation material surfaces, use of conductive or electrostatic conductive transport or conveying systems is also adequate protective action in this case. Electrostatics and its ignition risks is a very complex issue. The energy released in a static electricity discharge may vary over a wide range. The energy in joules can be calculated from the capacitance (C) of the object and the static potential V in volts (V) by the formula E = ½CV . One experimenter estimates the capacitance of the human body as high as 400 picofarads, and a charge of 50,000 volts, discharged e.g. during touching a charged car, creating a spark with energy of 500 millijoules.
