Abstract
Employee exposure to ethylene-oxide (75218) (ETO) and dichlorodifluoromethane (75718) (Freon-12) were evaluated on March 6 and 7, 1978 in the anesthesia equipment room of Swedish Hospital (SIC-801) in Seattle, Washington. An evaluation request came from the hospital administration on behalf of approximately 24 affected workers. Two 15 minute breathing zone samples of ETO were 28 and 57 parts per million (ppm), respectively. Two general area samples were 41 and 37ppm respectively. The time weighted average exposure was approximately 10 to 15ppm. These were below the evaluation criteria of 75ppm for 15 minute periods. Freon-12 gas concentrations calculated on a ratio basis were well below the criteria of 1,000ppm. The authors conclude that there is no hazard from exposure to ETO or Freon-12. They recommend increasing ventilation, closing the cabinet door and opening the sterilizer door, and restricting entrance to the ETO area, medical surveillance preplacement examinations, counseling, and periodic medical examinations.
