Abstract
In response to a request from workers at the Aluminum Company of America (SIC-3334), Badin, North Carolina, an investigation was begun into possible occupational exposure to magnetic fields in the potroom. The Badin facility had two production lines composed of 248 pots distributed over four potrooms, with about 125 potroom workers. Static magnetic fields (SMF) and sub radiofrequency electric and magnetic field (SRE/MF) measurements were made at various locations inside the four potrooms at the company. Measured SMF levels were as high as 760 gauss (G) at workers' locations but the occupational SMF time weighted average was estimated between 125 and 150G. The SMF levels did not exceed the ACGIH threshold limit value of 600G. SRE/MF levels ranged from 1 to 5 volts per meter (V/m) and 0.3 to 3108 milligauss (mG) while levels of SRE/MF near the buss bars in all potrooms ranged from 2 to 4V/m and 5 to 25mG. The author concludes that both SMF and SRE/MFs were found in the potroom. Risers were the dominant SMF exposure source at the facility. Levels of both SMF and SRE/MFs did not exceed present occupational standards. Electricians and electrical workers were the one occupational group exposed to both SMF and SRE/MFs.
