Abstract
Worker exposures to nitrosamines were surveyed on July 13 to 15, 1982 at Sheller Globe Incorporated (SIC-3060) in Keokuk, Iowa. The evaluation was requested by an unspecified representative of the United Rubber, Cork, Linoleum and Plastic Workers of America International Union on behalf of the company's 50 workers. Personal breathing zone and process air samples were analyzed for nitrosamines, and air flow was measured in the extrusion local exhaust ventilation system. In personal air samples, respective concentrations of nitrosodimethylamine (62759), nitrosodiethylamine (55185), nitrosodipropylamine (621647), and nitrosomorpholine (59892) averaged 0.4, 0.2, 2.3 and 0.7 micrograms per cubic meter. Total nitrosamine concentrations averaged 3.6 micrograms per cubic meter. NIOSH recommends that exposures to these agents be kept to the lowest feasible limit. In process air samples, nitrosodibutylamine (924163) was also found. Face velocities of the hood ranged from less than 50 to 600 feet per minute, and capture velocities ranged from less than 50 to 400 feet per minute. The author concludes that a nitrosamine exposure hazard exists at his facility. He recommends improvements in engineering controls and workplace design.
