Industrial Hygiene Survey at Reynolds Metals, Listerhill Reduction Plant, in Sheffield, Alabama.
NIOSH 1973 May:60 pages
Worker exposures to dust, coal-tar-pitch (65996932) volatiles, fluorides, carbon-monoxide (630080), sulfur-dioxide (7446095), hydrogen-fluoride (7664393) and ammonia (7664417) were surveyed at Reynolds Metals (SIC-3334) in Sheffield, Alabama from February 12 to 16, 1973. The factory employed 1100 persons, a medical director and 6 nurses. Pre-employment examinations were given and the factory had industrial hygiene and safety programs and committees. Personal and stationary samples were collected for total dust and coal-tar- pitch volatiles, fluorides, carbon-monoxide, sulfur-dioxide and ammonia. Concentrations of total airborne dust, the benzene soluble fraction of coal-tar-pitch volatiles, particulate fluorides, gaseous fluorides, sulfur-dioxide, hydrogen-fluoride, ammonia, carbon- monoxide and noise ranged from 1.7 to 61.8 milligrams per cubic meter (mg/Cu m), from 1.1 to 60.0mg/Cu m, from 0.014 to 0.173mg/Cu m, from 0.021 to 0.95mg/Cu m, from 1 to 2 parts per million (ppm), not detected, from 12 to 50ppm, from 5 to 70ppm and from 65 to 108 decibels, respectively. The author concludes that excessive exposures to total airborne dust and to the benzene soluble fraction of coal-tar-pitch volatiles occurred in the potroom. He recommends respiratory protection for affected workers, engineering controls to reduce concentrations of coal-tar-pitch volatiles, and hearing protection devices for workers exposed to excessive noise.
