Worker exposures to hazardous agents were surveyed on January 22 to 24, May 8, and July 30, 1980 at Scott, U.S.A., (SIC-3949) in Clearfield, Utah. The evaluation was requested by the company's Executive Vice President on behalf of 250 employees, to assess worker reports of menstrual disorders and central nervous system (CNS) symptoms. Air samples were analyzed for various contaminants, and workers completed health symptom questionnaires and were given complete medical examinations. In the Ski Boot and Motorcycle Boot Assembly Areas, methylene-chloride (75092), tetrahydrofuran (109999), methyl-ethyl-ketone (78933), and toluene (108883) concentrations ranged from 2 to 318, undetectable to 783, 2 to 690, and 0.4 to 53 milligrams per cubic meter (mg/cu m), respectively; corresponding OSHA standards are 1740, 590, 590, and 750mg/cu m. Workers reported headaches, dizziness, sleepiness, fatigue, and skin irritations. The incidence of respiratory or menstrual disorders was not significant. The authors conclude that workers in the Ski and Motorcycle Boot Assembly Areas are exposed to hazardous amounts of methylene-chloride, methyl-ethyl-ketone, tetrahydrofuran, and toluene. Recommendations are included for improved work practices, personal and workplace hygiene, ventilation, and respiratory protection.
