How Important is to Maintain Cleanliness? Clean rooms in Pharma laboratories and various FMCG industries need to maintain certain quality of air to meet their needs of cleanliness or inhibit any kind of micro-organisms in the vicinity. Even the person in the lab has certain value of microbes on their skin especially hands which could be readily transferred in to the product or critical area or objects if not taken with enough care. Such microbes are either present on the skin not multiplying like pre-existing flora, which can include a wide range of environmental microorganisms like Staphylococcus, Pseudomonas etc or are multiplying microorganisms released from the skin like residential flora coming from the families of Micrococcus and Propionibacterium. Of the two groups, residential flora is more difficult to get rid of. For utmost important operations, some protection is taken by wearing gloves to inhibit these creatures. However, gloves are not suitable for all activities and you have to undergo frequent sanitization or if they are of an unsuitable medium they will catch up and transfer via cross contamination. Considering all these value points, sanitization of hands and surfaces in healthcare settings and in cleanrooms is of extreme importance while dealing with bulk drug production or any research which involves lots of effort and time, as carelessness at any point of operation could cost the company heavily.
