This book describes how to conduct Process Hazard Assessments (PHAs) for processes handling combustible solids. The book explains how to do a dust hazard assessment by using either an approach based on compliance with existing consensus standards, or by using a risk based approach. Worked examples in the book help the user understand how to do a combustible dust hazards assessment.
