Risk of microbial spores in cleanrooms

The risks posed by microbial spores pose to cleanrooms in terms of their survival mechanisms and, in the case of fungi, ease of dispersal, are substantial. One means to address this is through the use of a proven sporidical agent. This is the subject of a new article by Tim Sandle.

The article considers the use of sporicidal disinfectants, examining different types and considering the range of factors that affect sporicide efficacy. Importantly, the selection of sporicidal agents is not straightforward. Several types of sporicidal agent are extremely corrosive to stainless steel, plastic and soft metals as well as being a potential health hazard to operators. For this reason, such agents tend to be used sparingly alongside other disinfectants.
