Hazard and Operability (HAZOP) studies are used to identify hazard scenarios for a process to manage risks. Often, they focus on the equipment used in a process which may lead study teams to overlook hazard scenarios resulting from the procedures not being followed. HAZOP studies are performed on procedures to identify such scenarios and help ensure study completeness.

HAZOP studies for batch processes and other non-steady state processes such as multiple operating modes for continuous processes are more complex than studies for steady state processes. Process hazards may change from one operating mode or process step to another. It is essential that hazard scenarios be identified for all process states to ensure a complete study.

This technical briefing provides guidelines for performing HAZOP on procedures and non- steady state processes, such as batch processes. Attendees receive an electronic copy of the technical briefing materials.

What you will learn:

  • Need for HAZOP on procedures
  • How to specify design intent for HAZOP on procedures
  • Use of custom and auxiliary HAZOP guide words
  • How design intent influences node assignment
  • When to perform HAZOP on procedures
  • Guidelines for performing HAZOP on procedures
  • Typical problems with procedures
  • Special features of HAZOP for batch processes
  • HAZOP deviations for batch processes
  • Treatment of batch recipes
  • Guidelines for performing HAZOP on batch processes
