In response to a request from management at the Integrated Performance Solutions, Inc. (SIC-3634), Boulder, Colorado, an evaluation was undertaken of occupational exposure to 60 hertz (Hz) electric and magnetic fields from an electrical resistive heating system. The company was a two person high tech consulting firm that provided software and computer support to other companies. The heating system at the facility can produce both electrical and magnetic fields. These fields, if they were at certain magnitudes, could pose occupational radiation exposure hazards. The heating system used a continuous bronze screen mesh in the floor as the resistive element. Extra low frequency (ELF) measurements were made on the heating system at two different locations. The maximum ELF levels were 200 volts per meter (V/m) and 10 milligauss at one location and 4.9V/m and 1.9 gauss at another location. The levels suggested by the American Conference of Governmental Industrial Hygienists Threshold Limit Values were 25,000V/m and 10 gauss, respectively. While the author concludes that no hazard existed at the time of the survey, the author recommends specific measures which should reduce the exposure even further.
