Control Technology Feasibility Study: The Use of Engineering Controls in Hospitals, Preliminary Survey Report of St. Francis - St. George Hospital, Cincinnati, Ohio

摘要

A survey was conducted to evaluate control measures for ethylene-oxide (75218) (EtO) at the St. Francis/St. George Hospital (SIC-8062) in Cincinnati, Ohio, on May 11, 1983. Information was obtained on the techniques and procedures used for maintaining low concentrations of EtO and measurements were made to determine worker exposures. The highest exposures occurred when the sterilizer door was opened after a cycle, reaching concentrations of 1,000 parts per million (ppm). Personnel exposures, equipment leak testing, and general ventilation systems were monitored. The authors conclude that St. Francis/St. George Hospital has instituted comprehensive control measures, the most effective of which is the local exhaust ventilation system. They recommend the hospital be included as an indepth survey site.
