Abstract
The intensity of electric and magnetic fields generated by heat sealing presses was measured during a NIOSH walk-through survey on April 6, 1979 at the Fabrico Manufacturing Corporation, (SIC-3079), Chicago, Illinois. Fabrico employed approximately 55 heat sealer operators at the time of the survey. Fabrico's heat sealing presses use radio frequency (RF) radiation to heat and seal a variety of plastic products. The surveyors corrected the magnetic field intensities of the presses for duty cycle to determine press operators' exposure while presses were operating. Electric and magnetic field measurements using a broad band isotropic radiation monitor revealed that guidelines for electric and magnetic fields were exceeded on four of eight heat sealing machines. Although a proven hazard was not documented, the authors suggest that a resonant heating of the body could occur at frequencies above the guidelines and recommend the addition of shielding to the heat sealing machines to reduce employee exposure. They also suggest that the cohort at Fabrico is not large enough for a health effects study, but future visits to other facilities which fit the criteria may provide a suitable study group.
