The Hazard and Operability (HAZOP) method is a recognized and widely used scenariobased hazard evaluation procedure. Within HAZOP studies, processes, process plants, and equipment are systematically examined to identify and assess potential hazards and operability issues. Thus, the HAZOP method contributes to prevent accidents and increase ...

In a HAZOP (Hazard and Operability) study, a package (or a facility) is broken down into 'nodes' on a 'PID'. Each node will be examined under the direction of a number of guidewords such as high pressure, low pressure, low flow, high flow, no flow, reverse flow, etc. Some guidewords will become specific to each system or team.

A typical HAZOP analysis can take 18 weeks to complete, costing over 13 00025 000 per week. By an OSHA estimate, approximately 25 000 plant sites in the United States require a PHA (Freeman, Lee McNamara, 1992). An estimated 5 billion is spent annually by the chemical process industries (CPI) to perform PHAs and related activities.
