Process Safety
Hazard and Operability Study (HAZOP)
A structured multidisciplinary review that uses guidewords to identify process deviations, causes, consequences and safeguards.
Why it matters
HAZOP is widely used to challenge design and operating assumptions before risks are accepted or changes are implemented.
