DHA 204: Dust Hazard Analysis

COURSE DESCRIPTION                                                                                  DURATION: 3 Days

The course provides a detailed procedure to conduct either a risk-based dust hazard analysis or prescriptive dust hazard analysis. A brief background introduction is covered along with knowing combustible dust physical and chemical properties, combustible dust hazards, and applicable regulations/codes/standards for dust hazards controlling. Combustible hazards protection is another section provided in this course based on process design, equipment selection, building construction, ignition source control, and dust hazards management. Participants will learn to utilize engineering controls to prevent and mitigate combustible dust hazards.
