In response to a request from a management representative an evaluation was made of an outbreak of illness at the Cincinnati Electronics Corporation (SIC-3663) located in Cincinnati, Ohio. The company manufactured electrical circuit boards and electrical equipment for the commercial and defense industries. In September of 1988 two boilers were prepared for operation by adding corrosion inhibiting chemicals, diethylaminoethanol (100378) and cyclohexylamine (108918). Steam produced by the boilers was used for humidity in the work area. Symptoms consistent with acute toxic effects of diethylaminoethanol and cyclohexylamine were noted in 65 of the employees. These included nausea, dizziness, vomiting, and eye, nose, and throat irritation. A significantly higher risk of having several symptoms was noted among the employees in the areas humidified with boiler steam than among employees in the nonboiler steam humidified areas. Employee exposures to metals from solder fumes and methyl-ethyl-ketone (78933) were all below established limits. There was friable asbestos (1332214) insulation exposed on one boiler. The authors conclude that the exposures to the two corrosion inhibiting chemicals were responsible for the workers' symptoms. Following this outbreak the company suspended the practice of using steam from the boilers to humidify the building.
