The only references to the frequency of steam, quality testing are to be found in HTM 2010, where it is indicated that steam quality should be tested as part of the annual revalidation exercise for each sterilizer. Where steam systems are either routinely or irregularly shut down, large quantities of air will be present in the distribution system on restarting. It is recommended that in such circumstances a comprehensive and validated venting procedure should be applied and testing for non-condensable gases is appropriate. |
