Back to the Future: Why are we doing this HAZOP?

摘要

Hazard & Operability reviews (HAZOP) and other forms of Process Hazard Analysis (PHA) have been an integral part of the design verification of process plants for several decades. These ubiquitous tools have been used in their various forms for everything from large scale multi-billion dollar projects through to periodic plant safety analyses and to validating the integrity of minor plant modifications. As with many human endeavours these design verification processes have been born in response to disasters involving significant plant damage and worse still, loss of life.
