This handy volume is a ready "go to" reference forthe chemical engineer, plant manager, process engineer, or chemistworking in industrial settings where dust explosions could be aconcern, such as the process industries, coal industry, metalindustry, and others. Though dust explosions have been aroundsince the Earth first formed, and they have been studied andwritten about since the 1500s, they are still an ongoing concernand occur almost daily somewhere in the world, from bakeries tofertilizer plants.
Dust explosions can have devastating consequences, and,recently, there have been new industrial standards and guidelinesthat reflect safer, more reasonable methods for dealing withmaterials to prevent dust explosions and resultant fires. This book not only presents these new developments for engineersand managers, but it offers a thorough and deep coverage of thesubject, starting with a complete overview of dust, how it forms,when it is in danger of exploding, and how this risk can bemitigated. There is also a general coverage of explosions andthe environments that foster them.
Further chapters cover individual industries, such as metal andcoal, and there is an appendix that outlines best practices forpreventing dust explosions and fire and how these risks can besystematically mitigated by these implementations. There isalso a handy glossary of terms for easy access, not only for theveteran engineer or chemist, but for the student or newhire.
This ready reference is one of the most useful texts that anengineer or chemist could have at their side. With so manyaccidents still occurring in industry today and so many hazards,this volume pinpoints the most common and easiest ways for theengineer to go about his daily business safely, efficiently, andprofitably, with no extraneous tables or theoreticaltreatises. A must have for any engineer, scientist, orchemist working with materials that could result in dust explosionsor fire.
