To prevent fires at gas stations, "touch metal or A charge of 10-5 amp sec per square meter only represents about one electron per 300,000 surface atoms (although each polymer “molecule” contains thousands of atoms). The first record of its effects dates to ancient Greeks who noted more than 500 years B. This 7. Electricity is LAZY, it always takes the SHORTEST and EASIESTpath, and the path usually leads to the “GROUND”. The New York Fire Department cautions against using fabrics made of wool, nylon and other synthetic materials around oxygen tanks because these fabrics are more likely to cause static sparks 3. When the electrostatic voltage reaches 2,000 volts, the fingers will feel; sparks will appear when the voltage exceeds 3,000 volts, and the fingers will have a needle-like pain; when the voltage exceeds 7,000 volts, people will feel a shock. In industrial settings, common sources of static discharge include Static electricity presents fire and explosion hazards during the handling of petroleum and tanker operations.
