Fundamentals of a Combustible Dust Safety Program

This course addresses the NFPA 652 requirements for dust testing and the associated Combustible Dust Hazards Analysis (DHA). The course will begin with a review of combustible dust heritage and the development of the current industry standards as they relate to the current NFPA 652 regulation. The course will then review methods and protocols for hazard identification, including dust characterization testing and data analysis for risk reduction. The second portion of this course will focus on how to organize, lead, and implement the DHA study. The course will address the tactics and success factors that help ensure a successful study. Participants will work in groups to apply DHA methodologies to example combustible dust scenarios. Instructors will work closely with the participants throughout this session/workshop to ensure that key principles are understood. By applying the DHA methodologies to practical example processes, the participants will internalize the principles presented and gain added insight to the value of performing thorough and accurate DHAs at their facilities. The combustible dust course will provide managers, engineers, safety professionals, and others involved in combustible dust programs with an understanding of the practices and procedures that are required to ensure safe operation and regulatory compliance.
