About the course

The risk review techniques most popular for initial PHAs of entire units or of large projects and PHA revalidations are hazard and operability (HAZOP) analysis and what-if/checklist. Both of these techniques facilitate systematic, imaginative searches for process hazards and potential operational difficulties.

The Course focuses on human factors issues and how to analyze for human errors that can occur in step-by-step procedures.

## Course Objectives

Upon successful completion of this course, the delegates will be able to:

  • Practice leading and participating in several analysis and to be familiarize with the techniques or the original form of the HAZOP techniques for effective analysis of procedures of startup, shutdown, normal batch operation, emergency operation, etc.
  • Perform a process hazard analysis with the critical elements that includes preparation of the PHA, scope, collecting information, selecting team and etc.
  • Apply the methods of HAZOP, FMEA, and/or WHAT-IF/checklist analysis to process systems
