“…Therefore, SEM imaging was considered as an important aspect of our work to further assess how far technical lignins studied may vary from this endpoint. Another key interest of SEM imaging is the potential observation of particle agglomeration phenomenon, another key aspect in organic dust explosion risk evaluation [ 37 ].…”

“…Many of the researchers have conducted dust explosion studies such as use of modelling for the aluminium dust venting Song et al (2019), the thermal characteristics of nano-polyethylene dust explosion studies Sun et al (2019), effects of the sodium bicarbonate suppression on the dust explosion of the polyethylene have been studied Wang et al (2020), testing aspects of the flammable powder dust before and after drying process Wei et al (2020) and various prediction models resulting in the dust explosion due to the usage of the organic powder Pietraccini et al (2021). There is very less published information on the hazardous area classification of the pharmaceutical industry.…”

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.

“…Moreover, any process involving combustible dust should perform dust hazard analysis using NFPA standards, 30 including NFPA 652 (Standard on the Fundamentals of Combustible Dust) and NFPA 654 (Standard for the Prevention of Fire and Dust Explosions from the Manufacturing, Processing, and Handling of Combustible Particulate Solids). 18 If it is necessary to change or adjust any facility to accommodate the combustible dust, the NFPA 68 31 (Standard on Explosion Protection by Deflagration Venting) and NFPA 69 (Standard on Explosion Prevention Systems) are recommended to be followed. 32 As for recommendations, programs for extruded food production factories should provide welding and metal cutting training to prevent dust explosions.…”

Dust explosions in compressed food factories can cause severe injury and death as well as damage to assets. This research aimed to assess the risk of dust explosions using the Fault Tree Analysis (FTA) technique from grain extruded food production. The results showed that there were possible situations in which 14 dust explosions were generated at the belt-drying area of puffed food. Considering some fundamental factors, the primary reason for the most significant dust explosion risk is seen to be welding/cutting operations. These processes create a source of ignition or heat in the environment. Therefore, an extruded food production factory should train welding and metal cutting to prevent dust explosions. Moreover, a flameless venting device and an explosion suppression detector should be installed in dust collectors. The FTA method demonstrated the risk of a dust explosion caused by machinery and equipment that must be reduced and controlled to an acceptable level to prevent the occurrence of dust explosions, which has a serious impact on occupational health assets and the environment.
