Health Hazard Evaluation Report HE 80-203-960, Phillips Chemical Company, Toledo, Ohio

摘要

On July 12, 1980, the National Institute for Occupational Safety and Health (NIOSH) received a request for a Health Hazard Evaluation from Local 7-346 of the Oil, Chemical, and Atomic Workers Union (OCAW) to evaluate possible adverse health effects of workers exposed to carbon black, carbon monoxide, and welding fumes at Phillips Chemical Company's carbon black plant in Toledo, Ohio. An initial site visit was made on August 19, 1980. A follow-up environmental/medical evaluation of 28 production workers was conducted on December 17-18, 1980. On the basis of the data collected in this survey, NIOSH determined that a hazard of overexposure to carbon black containing PNA's (via cyclohexane extractable fraction) did exist at Phillips Chemical Company at the time of this survey. NIOSH recognizes that PNA's, which were detected in the personal air samples, have carcinogenic or cocarcinogenic potential. Therefore, NIOSH recommends that exposure be controlled to the lowest reliable analytical detection level.
