e-Training: Process Hazard Analysis (PHA) Best Practice

COURSE DESCRIPTION                                                                                 DURATION: 1 Day, 9AM-4PM

The objective of this course is to provide a better understanding of the importance of certain aspects of PHA facilitation and the best practices that should be used during a PHA study. Using these best practices will reduce time, confusion and quality of the PHA. This course will also highlight the “dos and don’ts” in a PHA study. The participants will learn to organize and lead process hazard analysis studies using the HAZOP and “What-If” techniques. Participants will discover the tactics and success factors that help ensure a successful study. They will also learn about and use software available for documenting PHA studies. This course teaches process hazard analysis (PHA) techniques and prepares each participant to lead teams and effectively perform and document HAZOP and other hazard/risk management studies. 


  • Learn to organize and effectively and efficiently lead and document PHA studies in accordance with local regulatory and industry “best practices” using the HAZOP, What-If, Checklist and other methodologies.
  • Learn the techniques and mechanics that help ensure a successful study.
  • Learn about and use software available for documenting PHA studies.
  • Obtain useful tools, checklists, and other aids for reference in future PHA studies.
