As per the united kingdom suggestions, by using a 5-min exposure, the normal bacterial depend must not exceed 35 bacterial and/or fungal particles per cubic metre of ventilating air. In the same way, the Geneva suggestions will take the conventional of 25 CFU/m3 for an vacant OR and a hundred and eighty CFU/m3 for 5-min exposure. The working issue of HEPA filters needs to be checked to start with. In correctly functioning HEPA filters, the quantity of airborne microbial contamination is rather reduced. In unidirectional air circulation zone, microbiological sampling is completed through the four corners on the perimeter zone, one from the center and four within the internal corners of your inner zone.
