Environmental and breathing zone samples were analyzed for ethylene- oxide (75218) in the central service area of Middletown Hospital (SIC-8062), Middletown, Ohio in August, 1985. Engineering controls and work practices were investigated. All time weighted average (TWA) breathing zone ethylene-oxide concentrations were below the OSHA standard of 1 part per million (ppm). Two samples, 0.14 and breathing zone ethylene-oxide concentrations ranged from non detectable to 0.27ppm. Environmental concentrations ranged from non detectable to 144.83ppm. Overall, ethylene-oxide exposure potential was reduced by local exhaust ventilation systems situated over the door of the sterilizers. The excessive exposures were due to a crimp in the liquid/gas separation exhaust hose and inadequate general ventilation of the mechanical access room. Effective work practices included pulling instead of pushing carts containing sterilized items and wearing cotton gloves when unloading sterilizers. The authors conclude that the ethylene-oxide exposure potential can be reduced by installing a pressure differential alarm system and improving ventilation in the mechanical access room.
