Common Process Safety Hazards
One of the philosophies of Process Safety Management (PSM) is that each chemical process is unique. Therefore it is not possible to have a prescriptive standard that tells operating companies what to do. Instead, companies have to identify the hazards associated with their facility, and then implement corrective actions based on a risk-ranking methodology. For this reason, facilities covered by PSM standards generally conduct a series of Process Hazards Analyses (PHAs), often using the Hazard and Operability (HAZOP) methodology.
