• Description:
  Environmental and breathing zone samples were analyzed for acrolein (107028), dimethylethylamine (124403), ammonia (7664417), formaldehyde (50000), furfuryl-alcohol (98000), hexamethylenetetramine (100970), and methylene-bisphenyl-isocyanate (101688) (MDI) at Dotson Company foundry (SIC-3321, 3565), Mankato, Minnesota, in February and March 1983. The evaluation was requested by the employees due to reported symptoms of headache, dyspnea, eye and nose irritation, nausea, and blurred vision. Interviews were conducted with eight active and five laid off employees. The medical records of all employees, a total of 21, were consulted. Airborne concentrations of acrolein, furfuryl-alcohol, ammonia, hexamethylenetetramine, and MDI were below the detection limits. Dimethylethylamine concentrations were below recommended standards. Formaldehyde concentrations were 0.3 to 0.9 milligrams per cubic meter (mg/m3). The OSHA standard for formaldehyde is 3.7mg/m3. The most frequently reported symptoms included eye irritation, blurred vision, cough, dry throat, nausea, and dizziness. The authors conclude that employee exposure to detectable concentrations of formaldehyde has occurred. Four of 21 employees had X-ray evidence of silicosis. Recommendations include use of control devices to reduce formaldehyde exposures and further studies to evaluate silica (14808607) exposure.
