Because of their complexity, combustible dust hazards are frequently overlooked in many facilities and industries. Thus, combustible dust fires, deflagrations and explosions continue to occur at an alarming rate throughout the United States. Many of these combustible dust fires and explosions have severely injured many employees working at facilities where combustible dust(s) were processed, handled and/or merely present.
This presentation will discuss the combustible dust hazards associated with Additive Manufacturing (3D Printing) Operations, and how to assess and mitigate these hazards. Specific items that will be discussed include, but are not limited to testing/sampling (including developing a sampling plan), Dust Hazard Analysis (DHA), and explosion protection and prevention methods. Additional discussions on how the requirements specified in NFPA 652, NFPA 484, NFPA 654 and other combustible dust standards should be applied to Additive Manufacturing Operations will be addressed. Finally, this presentation will overview some of the most common inadequately identified or missed combustible dust hazards, and how these missed hazards impact the engineering of the process equipment associated with Additive Manufacturing Operations.
