An initial site visit was made to the facility on February 3, 1982. Because a number of the processes to be evaluated were operated intermittently or were not to be operational for several months, three follow-up visits were made over the following 18 month period to determine airborne levels of substances used in the manufacturing of semi-conductors. NIOSH determined that a health hazard did not exist for the students and faculty at the University of Cincinnati Semi-Conductor Laboratory during the time of the environmental evaluation. However, certain conditions exist such as the use of extremely hazardous substances, insufficient exhaust ventilation at certain fume hoods, and exhausting of toxic substances to the roof area, which may pose significant health hazards. Recommendations for reducing these potential health hazards are made in Section VII of this report. 收起
