Advanced Process HAZOP




Introduction:

It is universally recognized that for any company to succeed it must take a proactive approach to risk management. Over the last few years, Companies and several countries legislators have been focusing on Process Safety as a method to reduce the risks posed by hazardous industries. Process Hazard Analysis (PHA) is recognized as being a critical tool in the implementation of a successful risk management system.

As Hazard and Operability (HAZOP) studies are now recognized worldwide as being the qualitative risk assessment methodology of choice in the Process Industries, there will be additional focus on this specific aspect of Process Hazard Analysis
