Hazard Area Classification, Critical Zone, ATEX Standard


Identifying the various critical zones in the pharmaceutical industry, various protection to the electrical instruments / equipment’s and the ingress protection enclosures class based on the international standards are presented. Collecting the flammability data based on the MSDS. Classifying the various location in the form of various zones by using different international standards. Application of various ATEX standards, Temperature class and ingress protection for the different equipment’s. In the pharmaceutical industry the zone 1, zone 2, zone 21 and zone 22 were classified as four, two, three, and two locations. The VOC concentration were highest in the clean room was 8 ppm during the monitoring. The ATEX standard Ex d, Ex e, Ex I, Ex n and Ex p were used in various zones for different instruments or electrical equipment’s. Temperature class 400 o C, T2 was highest inside the boiler. Ingress protection class of IP65, IP66 and IP67 enclosures are used for the various equipment’s.
