Question

What actions are needed to address the presence of non-condensable gases?

Accepted Answer

Addressing the presence of non-condensable gases, primarily air, in a steam sterilizer requires a multi-faceted approach. First, ensure proper air removal during the pre-vacuum phase. This involves verifying that the vacuum pump is functioning correctly and that there are no leaks in the vacuum system. Perform a leak test on the sterilizer. The test confirms the integrity of the system. Secondly, inspect and clean the steam traps. Steam traps remove condensate and non-condensable gases from the steam lines. A malfunctioning steam trap can allow air to enter the sterilizer chamber. Next, verify the steam quality. Ensure that the steam supply is free from contaminants and that the steam dryness fraction is within the acceptable range. Implement regular boiler blowdown procedures to remove accumulated solids and impurities from the boiler water. Finally, ensure proper loading practices. Avoid overloading the sterilizer or packing items too tightly, as this can impede air removal and steam penetration. Regularly perform a Bowie-Dick test to assess the effectiveness of air removal. If the Bowie-Dick test fails, investigate and correct the underlying cause.
