Comparison of Hepa Filter Testing and Standard Particle Measurement in Clean Rooms
Journal Title: Scholars Journal of Engineering and Technology - Year 2014, Vol 2, Issue 1
Abstract
The high quality air without particle must be provided in operating rooms that are known as clean room. Particles cause the risk of infection in clean rooms. But, the infection risk ratio decreases by using a clean-air system. For a perfect clean room, the clean-air system must be controlled by measuring particles and must be classified in according to the international standard. The related standard is, ISO 14644-1:1999(E) Cleanrooms and associated controlled environments Part 1: Classification of air cleanliness. In according to the standard, the clean room is classified from ISO Class 9 to Class 1 by measuring of particles (0,1µm, 0,2µm, 0,3µm, 0,5µm, 1µm, 5µm). The clean room classification requires a scientific study. But, sometimes, the particle measurement, unfortunately, is performed by non-licensed personnel by only controlling of hepa filters instead of standard methods. In this case, the clean room can not be classified. The objective of this study, is to show the difference between the scientific measurement and the random measurement of particles, and resultly, to consider the unwanted results of the hepa filter testing. In this study, the particle measurements of an operation room were performed by controlling of hepa filters and by applying international standards, respectively. Thus, the results of two measurements were compared. This study announces that the nonstandard measurements that are performed by personnel without license, may cause to report a bad operation room as a good classified room. The subject needs the standardization and the biomedical professionality.
