The use of Process Hazards Analysis (PHA) techniques for hazard identification and assessment are becoming a standard process for many companies as a part of their overall risk management strategies. PHAs provide a systematic approach to studying process systems, identifying weaknesses and providing opportunities to increase overall system reliability through evaluation of existing controls and/or establishment of new control requirements. However inadequate evaluation or application of the proper control for each identified hazard scenario may result in reduced or ineffective risk reduction. In this presentation, criteria for evaluating risk controls to ensure maximum effectiveness will be discussed together with several specific examples from past PHA studies.
