Dust Hazard Analysis (DHA) and Hazardous Area Classification (HAC) Training

This one-day course provides an overview of dust hazard analysis (DHA) and hazardous area classification (HAC) and how the two concepts are combined in a combustible dust HAC study. Through this course, participants will gain an understanding of the current regulatory climate with regards to performing a dust HAC. Workshop examples will be discussed to allow for better understanding and a comparison of different standard methodologies. This course is ideal for PSM managers and process safety engineers who work on projects that include or at an operating facility that processes/stores combustible dust materials.
