Process Hazard Analysis Report July 2020 <br /> 3 Introduction <br /> This report documents the findings of a What-if/ Checklist study conducted for Oak <br /> Ridge Winery for the three (3) anhydrous ammonia processes at the Lodi, CA <br /> facility. Oak Ridge Winery does not exceed the federal threshold of 10,000 pounds <br /> in either of the three processes. However, they have adopted the program 3 <br /> prevention elements to bolster process safety. <br /> For the What-if questions, APCCO used an on-line software system that manages <br /> all aspects of a prevention program called APSM. Checklists were used for <br /> external events and human factor analysis. <br /> 3.1 Objectives <br /> The primary objective of the study was to systematically identify all credible safety <br /> hazards and operability concerns associated with the three (3) anhydrous <br /> ammonia processes. This included a complete review of the design and operation <br /> of the anhydrous ammonia process, and a focus on process safety hazards versus <br /> other occupational safety and health or environmental hazards. What-if combined <br /> with a checklist were used as analysis methods to assist the team in identifying <br /> possible hazards. The What-if methodology is widely recognized as a thorough <br /> process safety hazard analysis method for anhydrous ammonia systems. <br /> A secondary objective was to suggest means to reduce the risks of all the <br /> identified hazards, if the team concluded that a recommendation was justified <br /> based on risk. Where recommendations were made, the risks of the scenario were <br /> evaluated by the team and prioritized according to a qualitative risk ranking <br /> system. <br /> The study team members were guided through a systematic approach designed to <br /> address potentially significant incidents which have the potential to injure workers, <br /> cause damage to the process, cause damage to the environment, or result in <br /> significant business losses and interruptions. A detailed description of the What-if <br /> methodology is given in this report. <br /> 3.2 PHA Team Packet <br /> The PHA team packet that was developed for use during the prior PHA was <br /> distributed to the team members to enhance their understanding of the system. It <br /> was reviewed and revised as needed to reflect the current state of the processes. <br /> 7 <br />
