(111a) How to Conduct a Dust Hazards Analysis (DHA)

Abstract: Dust hazards analyses (DHAs) are required to be completed by September 2018 for all existing facilities, per NFPA 652. This presentation will compare and contrast the similarities and differences between chemical process hazard analysis and dust hazards analysis. It will discuss the basic dust characteristics and how to apply the information during the DHA. It will provide methodologies for conducting DHAs that will make the most efficient use of team time. Potential ignition sources to be considered during the DHA will be presented. An explanation of dust hazard assessment, how it differs from DHA, and how it can be utilized during the process will be provided. Application of a typical risk-ranking matrix approach to prioritizing recommendations will also be demonstrated. The attendee will leave with an understanding of what information is needed before undertaking a DHA, what tools are needed to successfully complete a DHA, and what to expect after the DHA is complete.
