Title Magnetic field exposures in a petroleum refinery
Bibliographic information June 1993, Vol.8, No.6, p.587-592. Illus. 9 ref.
Abstract Petroleum refinery workers were classified into groups based on the type of exposure sources and work conducted. Electricians were divided into three categories: high voltage electrical distribution (HVED) workers; low voltage electrical distribution (LVED) workers; and maintenance electricians (MNTE). A total of 48 individuals, 11 HVED electricians, 12 LVED electricians, 11 MNTE workers, and 14 controls were monitored for an 8-hour shift. Both the HVED and LVED groups were found to have average full-shift mean exposures slightly greater than 10 milligauss (mG). The MNTE group and the controls exhibited lower magnetic flux density exposures, with means between 2mG and 3mG. A special group of high voltage electricians were monitored during maintenance work on large current-limiting coils in the power distribution system. Individual full-shift magnetic field means ranged from 0.06 to 2.0 gauss (G), with an overall mean of 0.93G. Peak exposures ranged from 2.1 to 18G, with an average of 12.1G.
