HEALTH AND SAFETY IN PNEUMATIC SYSTEMS

Year 2015, Volume: 56 Issue: 662, 63 - 71, 09.04.2015

Abstract

Suitable choice and arrangement of pneumatic conveying equipment, materials can be conveyed from a silos in one location to another location some distance away. Flexibility in both plant layout and operation are possible. In vacuum systems, materials can be picked up from stockpiles, and they are ideal for clearing dust accumulations and spillages. Pneumatic conveying systems are particularly versatile. A very wide range of materials can be handled, and they are totally enclosed by the system and pipeline. This means that potentially hazardous materials can be conveyed quite safely with the correct choice of system and components. There is a minimal risk of dust generation, and so these systems generally meet the requirements of any local health and safety legislation with little or no difficulty. They do not allow dirt to contaminate the conveyed material but allow material and fugitive dust to escape into work place. The particles can endanger worker’s respiratory health or settle on plant surfaces, creating combustible dust hazard. To reduce safety hazards in conveying plant workers need to be learned most common job related injuires and illness. In this study, to reduce risks encountered in pneumatic conveying systems, security and solutions with the necessary means to increase efficiency providing an effective ways to justify the cost of systems are given.

PNÖMATİK SİSTEMLERDE SAĞLIK VE GÜVENLİK*

Year 2015, Volume: 56 Issue: 662, 63 - 71, 09.04.2015

Abstract

Pnömatik sistem elemanlarının seçimi ve düzenlenmeleri doğru yapıldığı sürece, bunkerlerden alınan malzemeler kolaylıkla taşınabilir. Tesisin düzenlenmesinde ve çalışma şartlarında yeterince esneklik vardır. Vakumlu sistemlerde, malzemelerin taşınmasında toz birikimine izin verilmez. Pnömatik sistemlerde, taşınan malzeme çeşitliliği oldukça büyüktür. Uygun sistem ve ekipmanlar yardımıyla, riskli malzemelerin emniyetli olarak taşınması mümkündür. Ayrıca, pnömatik sistemlerde toz oluşumunun zayıf olması, sağlık ve emniyet yasalarıyla uyumludurlar. Bu sistemler, taşınan malzemenin kirlenmesine izin vermezler. Ancak, çalışma ortamında malzeme ve toz kaçağının oluşumu kaçınılmazdır. Taşınan malzeme partikülleri, çalışanların solunum yolları için tehlikelidir. Bunların tesis üzerinde birikimleri, toz patlamalarına neden olabilir. Bu çalışmada, pnömatik taşıma sisteminde karşılaşılan riskleri azaltmak, güvenlik ve sistem verimliliğini artırarak maliyeti düşürmek için gerekli yöntemlerle birlikte çözümler de verilmiştir.
