Abstract
Worker exposures to iron-oxide (1309371) and treated amorphous silica (7631869) dust were surveyed at S.W.S. Silicones Corporation (SIC-2869) in Adrian, Michigan on August 22 and 23, 1979. The evaluation was requested by the United Steelworkers of America, Local 7237, on behalf on an unspecified number of employees. Environmental samples were collected and 29 workers were questioned about work related health problems. Exposures to amorphous silica ranged from 0.15 to 10 milligrams per cubic meter; the OSHA standard is 20 million particles per cubic foot. All samples for iron-oxide were below the OSHA limit of 10 milligrams per cubic meter. Cyclohexylamine (108918) also was detected in concentrations up to 1.8 parts per million; no OSHA standard exists for this compound, however the threshold limit value of the American Conference of Governmental Industrial Hygienists is 10 parts per million. Workers commonly reported eye, nose and throat irritations, and a few also complained of headaches and respiratory difficulties. The authors conclude that a potential hazard exists from silica exposure. Recommendations include installation of an enclosed catalyst delivery system, use of local exhaust ventilation, worker education concerning good work practices and personal hygiene, and periodic environmental monitoring.
