AN74i VENT PUMP FAILURE DOES NOT POSE ETHYLENE OXIDE EXPOSURE RISK
This study1 was conducted to determine the consequences of a ventilation pump failure in an Andersen AN74i sterilizer. Ofparticular concern was possible operator exposure to ethylene oxide (EO) in the vicinity of the sterilizer. Measurements taken at the cycle’s peak concentration of EO resulted in an undetectable level (< 1part per million). CONDITIONS: The temperature inside the sterilization liner bag measured at 24.3 to 25oC. The relative humidity ranged from 42.4 to 60.5 percent. The test room itself had no airchanges. Performing the test in an unventilated room increases the risks associated with a malfunction of this kind. Andersen Products, Inc. recommends that the sterilizer be installed in a room with atleast 10 air changes per hour. Operation of the sterilizer in a room with no air changes constitutes a gross misuse of the system. MATERIALS:
