Item Restricted Process Safety Analysis in Mining(The University of Queensland, 2024-11-04) Fallatah, Mohammed; Hassall, MaureenMany people associate process safety events such as loss of containment, fire, or explosions with the chemical and refining industries. However, these catastrophic incidents have also occurred in the mining and mineral processing industries in recent decades. Learning from incident investigations, public inquests, and operational feedback is a vital safety element that provides background for regulators and policymakers and offers opportunities to ensure similar shortcomings do not arise in major hazardous sectors. However, no focus on process safety incidents relevant to the minerals processing industries could be found when searching such databases. Through a comprehensive literature review, this research addresses this gap by exploring whether such databases can be built and populated with publicly available information. The Preferred Reporting Items for Systematic Review and Meta-Analysis (PRISMA) method was used to systematically identify, evaluate, and analyze existing literature data. Thirty-three global incidents relevant to mineral processing were obtained, and their root causes were analyzed against established frameworks for process safety management systems and risk prevention approaches. Regions and locations of the incidents were also captured. Human, economic, and environmental impacts were recorded where available. 34% of the accidents' primary causes were equipment failures, leading to a loss of mechanical integrity; 12% were attributed to design failures related to structural integrity; 33% were unknown or unreported causes; and the rest were a combination of human error and failures of administrative systems. Incidents found through web searches lack essential details, while those found in organizations' press releases and governmental agencies are more detailed. The conclusion suggests adapting PSM in the mineral processing industries.14 0Item Restricted HAZID Analysis of Hydrogen Production Via Solid-State Electrolysis(The University of Sheffield, 2024-08) Altarif, Saleh; Cordiner, JoanCarbon-neutral energy sources are required for efficient energy production in the future, which has prompted research on new methods for generating Hydrogen or clean hydrogen production technology, such as solid oxide electrolysis cells (SOECs). Nevertheless, the high-temperature operation of SOECs and hydrogen handling aspects pose severe safety and environmental concerns. This study thus performs a thorough Hazard Identification (HAZID) on hydrogen production using SOECs with the objective of overcoming these challenges to allow for safe use and integration of the technology. This paper covers measures necessary to determine risks associated with SOEC systems, such as high heat, electrical appliances, chemicals, and pressure. The study concludes that the current approaches used in HAZID do not adequately incorporate some of the potential dangers with SOEC operation; therefore, improvements are needed in assessing SOE chamber material degradation at high temperatures as well as the integration of SOECs with other forms of renewable energy sources that are intermittent. To improve risk evaluation and management, the study suggests the implementation of innovative technologies, including CFD, ML, and real-time monitoring. The study highlights the dire call for enhanced safety measures, measurement, and control, as well as constant technology innovation to attain safe implementation of SOEC technology for the steady production of Hydrogen.28 0
