Health Hazard Evaluation Report HETA 91-0337-2466, Aluminum Company of America,Badin, North Carolina

摘要

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. 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. 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.
