Precaution and rapid assistance with contaminated potable water systems in the hospital area
- recognised method for cleaning and disinfecting contaminated cooling water systems in dental units
- effective against legionella, pseudomonads, mycobacterium chelonae as well as algal and bacterial biofilms
- accredited water sampling and analysis
In a supply water pipe of a dentist’s chair, the colonisation of Mycobacterium chelonae was detected in the biofilm. Elimination of the bacterium by chlorination turned out to be ineffective.
… In this case, experience has shown that chlorination generally fails, even as high chlorination. If the contamination affects the cold water network, success can be expected with chlorine dioxide.
… Prior to this, alkaline cleaning (e.g. muEX forte) should be carried out.
