Abstract

ANSI/IEEE Std. 80-1986 states that the electrical resistance of shoes is uncertain and that it may be very low for damp leather. Therefore, for purposes of the guide, the electrical resistance of shoes is assumed to be zero. It is believed that the use of zero ohms is unduly conservative for electric utility employees working at job sites where workshoes are required and results in unrealistic work restrictions. Present day work shoes utilize a rubber-based compound in the outer sole of the shoe that is especially moisture and oil resistant. Based on these considerations, Niagara Mohawk Power Corporation (USA) has established a conservative, but more realistic, shoe resistance of 2000 ohms for calculation of step and touch potentials for employees working on or near overhead electric lines
