Dust hazards analyses (DHAs) are required to be completed for all existing facilities, per National Fire Protection Association (NFPA) Standard 652. This paper compares and contrasts the similarities and differences between chemical process hazard analysis and DHA. It discusses the basic dust characteristics and how to apply the information during the DHA. It provides methodologies for conducting DHAs that will make the most efficient use of team time. Potential ignition sources to be considered during the DHA are presented. An explanation of dust hazard assessment, how it differs from DHA, and how it can be utilized during the process is provided. Application of a typical risk‐ranking matrix approach to prioritizing recommendations is demonstrated. The reader will gain 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. © 2018 American Institute of Chemical Engineers Process Saf Prog 38: e12004, 2019
