What is the difference between FMEA and HAZOP?
Both FMEA and hazard analysis examine functions, failures modes, effects and causes. The primary difference with a hazard analysis is that it focuses entirely on safety hazards, whereas the scope of an FMEA covers safety as well as performance, quality and reliability.
