The IChemE Safety Centre (ISC) have released a guidance document on a risk assessment technique called Delta HAZOP. The traditional HAZOP process 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, or another form of PHA continues to be repeated through the life of a facility, the finding of significant issues is likely to decrease after two or three cycles. Therefore, to achieve a high-quality output, where items of significant value are uncovered it was necessary to look at the process differently.
This realisation led to the development of a process known as Delta HAZOP. The focus is on understanding the creeping changes to the process that have occurred and ensuring that the risks associated with them have been understood and addressed. This does not negate the need for a robust Management of Change process. Join us for a webinar explaining the process as defined in the guidance document.
