In response to a request from the union and management team at ARMCO Steel Company (SIC-3325), Ashland, Kentucky, an investigation was begun into possible employee exposures to various types of electromagnetic radiation fields at two locations: the galvaneal unit on the coating line, and the ladle refiner at the slab caster. At the time of the study, ARMCO produced a broad range of flat rolled steel products in its 700 acre facility and employed over 1,300 workers. Approximately 30 workers were involved with the galvaneal unit and over 40 workers were involved in ladle refiner activities. Measurements obtained at the facility demonstrated extremely low frequency fields that produced magnetic field levels ranging from 0.17 to 1.34 gauss (G) and electric field levels ranging from 2.8 to 17 volts per meter at various locations. Personal exposures for workers ranged from 0.1 to 1.48G. The galvaneal coating unit, which operated at 9.9 kilohertz, emitted very low frequency magnetic field levels in excess of the threshold limits. The author concludes that a potential health hazard existed on the days of measurement from exposure to magnetic fields produced by the galvaneal coating line unit. The author recommends that exposure levels be reduced.
