Abstract
Industrial hygiene data were collected during a reproductive health study of workers exposed to 2-ethoxyethanol (110805) (2EE) at Precision Castparts Corp. (SIC-3369), Portland, Oregon. Air concentrations of 2EE were high, most likely as a consequence of the nature of the investment casting process. Twenty two of 27 personal air samples exceeded 5 parts per million (ppm), with an average of 10.7ppm. All environmental measurements were below the prevailing OSHA Permissible Exposure Limit of 200ppm. Persistent, detectable concentrations of ethoxyacetic-acid (627032) (EAA), a suspected major metabolite of 2EE, were found in urine samples from exposed workers but not in samples from unexposed subjects. The author concludes that urinary monitoring can be used for assessing exposure to 2EE, particularly if there is skin exposure. The author recommends a followup reproductive health study to judge impairment of reproductive function. 2EE use has been discontinued at this facility. As the process was not changed, the substitute solvent may be rapidly vaporized into the air resulting in high concentrations which must be evaluated. Long sleeved coveralls are recommended for all workers. These should be laundered regularly and not worn home. The ventilation systems should be evaluated. A continuous program of industrial hygiene assessment should be instituted.
