HHE report no. HETA-86-403-1747, St. James Community Hospital, Butte, Montana.
NIOSH 1986 Nov; :1-12
Management requested an evaluation of exposures to nitrous-oxide (10024972), ethrane (13838169), and isoflurane (26675467) in the surgical department at St. James Community Hospital (SIC-8070), located in Butte, Montana. Air samples were collected and evaluated for ethrane content, at which time, five of the 13 samples were found to exceed the NIOSH evaluation criteria of 0.5 parts per million (ppm), being measured as high as 2.5ppm. Three of 13 isoflurane samples exceeded the criteria of 0.5ppm, with a maximum recorded concentration of 4.1ppm. Nitrous-oxide content was determined in 20 breathing zone air samples; two showed concentrations exceeding the criteria of 25ppm. The health hazard was confirmed for exposure to ethrane, isoflurane, and nitrous- oxide. It was recommended that anesthesiologists check slip connections and the high pressure nitrous-oxide connections, as these are areas where high concentrations in the workroom air were noted. Continued maintenance of the flexible hose going to the ventilation system from the popoff valve should be instituted.
