Process Hazard Analysis (PHA)


Comprehensive hazard identification is the cornerstone of effective risk management.  This course covers practical methods for performing process hazard analyses (PHAs) of systems and procedures, using the hazard and operability (HAZOP) and what-if/checklist techniques.  It teaches participants the methods used to identify hazard potential and their consequences when plant/equipment operates outside its design intent.


At the end of the course you will be able to

  1. Select the most appropriate technique for the PHA
  2. Apply PHA techniques to identify hazards, clearly define the consequences and challenge the suitability of the safeguards
  3. Report and document the findings from the PHA
