THE MEASUREMENT OF HUMAN CAPACITANCE AND RESISTANCE IN RELATION TO ELECTROSTATIC HAZARDS WITH PRIMARY EXPLOSIVES
Abstract
The electrical capacitances of a number of subjects wearing insulating or conductive types of footwear on various insulating or conductive floors have been measured. The values range from 150 - 300 micromicrofarads for insulated conditions to 700 - 1500 micromicrofarads for conducting conditions. The effective skin resistances during electrostatic discharges from the hands and finger tips have been determined; also several measurements have been made under low-voltage continuous-current conditions. The values of resistance determined by the dynamic method are considerably smaller than those given by the low-voltage method. The results of the capacitance and resistance measurements are discussed in relation to the electrostatic hazard of handling primary explosives, and to a possible circuit equivalent to a discharging person.
