Field Survey of the White Pine Copper Company, White Pine, Michigan.
NIOSH :24 pages
Crushing, smelting, and casting operations were surveyed at the White Pine Copper Company (SIC-3331) in White Pine, Michigan, on October 11, 1972. The company was under consideration for inclusion in a NIOSH study of the health effects of occupational exposure to sulfur-dioxide (7446095) (SO2), arsenic (7440382) (As), copper (7440508), dust, and fumes. About 2,900 employees worked at the facility. Preemployment examinations were given with periodically repeated chest X-rays and blood tests. Industrial hygiene monitoring of carbon-monoxide (630080) (CO), carbon-dioxide (124389) (CO2), nitrogen-dioxide (10102440) (NO2), and the free silica (7631869) content of dust was routinely performed and SO2 and hydrogen-sulfide (7783064) (H2S) concentrations were monitored above ground. The authors conclude that only the smelter operations require an extensive in depth survey. Crushing and flotation operations should be spot checked with personal pumps. SO2 should be monitored by the West-Gaeke method for accuracy. Dust samples should be analyzed for As, silver (7440224), lead (7439921), and silicon-dioxide (60676860).
