This is a two-day advanced course on dust and powder explosion hazards. The course addresess all aspects of dust explosion hazards. The emphasis of this course is dust properties, explosion modeling, preventive measures, ignition sources, protective measures, process hazard analysis, legislation, and case studies. It enables attendees to better understand dust hazards, to recognize potentially serious events, and to implement e�ective safeguards. The course will prove helpful to experienced engineers, safety supervisors, and operating managers who are committed to safe workplaces.
