This course will help experienced HAZOP leaders learn how and when to apply the Delta HAZOP process. 

The traditional HAZOP is a structured process that, when done well, produces a robust and thorough analysis of failure scenarios and identifies safeguards to manage the risk. Where a HAZOP is repeated, the finding of significant issues is likely to decrease after two or three cycles.

Delta HAZOP is a different approach that focuses on understanding the creeping changes to a process that have occurred. It ensures that the risks associated with the changes have been understood and addressed. Delta HAZOP is not a HAZOP as defined within the IEC standard. It is a technique to re-validate process hazards analysis.
