EMF Research - Lineworker EMF Monitoring PG&E Lineworker EMF Monitoring Study: Results of Personal

Recommendations for Guidelines for EMF Personal Exposure Measurements, Rapid Project #4

“…The exposures of transmission and distribution live line workers have also been investigated with PEM for various purposes [Gamberale et al, 1989;Pretorius, 1993;Bracken, T. D. et al, 1994a].…”

“…Within the utility worker group there are specific job titles that have been targeted because of their high exposures. In a study of line workers performing live-line tasks on transmission and distribution lines, Bracken et al [1994a] targeted workers performing specific tasks using specific work methods.…”

“…In a study of the magnetic field exposures of live-line workers, a special harness for holding the meter at the chest was designed with the assistance of the line workers [Bracken, T. D. et al, 1994a]. This placement ensured that wearing the meter did not interfere with performing tasks in an environment where safety is of paramount importance.…”

“…Breysse et al [1994b] estimated time performing work tasks from observations of subjects. In another study the time in task, as determined by observers' bar code scans, was integrated with estimates of task frequency and field measurements to produce annual exposure and time-in-field estimates [Bracken, T. D. et al, 1994a].…”

“…To accomplish this, traditional time-activity logs and/or observers have been used. In addition, time-stamped bar code scans have been used to delineate specific tasks or locations in some EMF exposure assessments [Sahl et al, 1993;Bracken, T. D. et al, 1994a].…”
