HAZOP Studies

This online course covers the concepts and techniques of the Hazard and Operability (HAZOP) Study methodology, including related matters of preparation, team meeting facilitation and reporting. It includes worked examples and references to additional resources.

Attendees will learn the anatomy of process safety incidents including process hazard analysis terminology, the basic HAZOP Study approach to developing potential incident scenarios, the estimating of scenario risk as a means to determining the adequacy of safeguards, the application of the HAZOP Study method to procedure-based operations, and the logistical aspects of planning and executing a HAZOP Study team review.

This course is the culmination of over 25 years of teaching and employing the HAZOP Study methodology in a variety of process industries, by the lead contract author of CCPS’ Guidelines for Hazard Evaluation Procedures, Third Edition and the instructor of the course "CCPS' HAZOP Studies and other PHA Techniques for Process Safety and Risk Management."

This course may be taken as part of the AIChE Credential for Sustainability Professionals (ACSP). More info
