HHE determination report no. HHE-78-42-498, Swedish Hospital, Seattle, Washington.
NIOSH 1978 May; :1-26
A health hazard evaluation was conducted to determine occupational hazards of ethylene-oxide (75218) (EtO) at Swedish Hospital (SIC- 8062) in Seattle, Washington, on February 16 and March 6 and 7, 1978. The survey was requested by the hospital administration on behalf of employees in the anesthesia equipment room. The time weighted average (TWA) exposure of the employee with the highest potential exposure to EtO was determined by collection by gas chromatography. Questionnaires were administered before and after the work shift to full time employees of the anesthesia equipment room. NIOSH recommended concentrations of EtO were 50 parts per million (ppm) for an 8 hour TWA and 75 ppm for a 75 minute short term exposure limit. Sample results showed a TWA concentration of EtO of 10 to 15ppm, and short term concentrations of 38 and 57ppm. These concentrations were well below established standards. There was no indication of post shift irritation of eyes, nose, throat, or skin of workers. The authors recommend increased exhaust ventilation of a cabinet door to permit closing, and medical surveillance of employees.
