Live online course – 19 July 2022, 14:00–17:00 BST.

Please note that this course is currently only available to people who have previously attended our HAZOP Leadership and Management course. 

This online 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 analyses.

Teaching will be delivered via one live online session (approximately three hours in length) and pre-recorded video content for independent study.

An e-certificate will be issued at the end of the course to confirm attendance and CPD hours logged. Please note that you must attend all modules to receive the certificate.
