Abstract

This study focuses on preventing electrostatic-related fires and explosions by analyzing key issues and proposing improvement strategies for managing electrostatic in fire and explosion hazards atmosphere. The research involved the analysis of 63 investigation reports from major electrostatic-related accidents between 2012 and 2021 and a survey of stake-holders. The investigation reports were examined for accident causes, investigation content, and prevention measures, while cross-analysis was used to identify frequent accident areas. To assess the current state of major electrostatic fire and explosion accidents in South Korea, we analyzed investigation reports and conducted surveys to identify key issues. Through this process, we identified areas in urgent need of improvement and discussed specific, actionable plans to enhance electrostatic safety management levels at industrial sites. Key improvements identified include: First, Developing specific investigation and procedural methods tailored to electrostatic fires and explosions. Second, Implementing safety measures for processes with inherent electrostatic risks and improving assessment techniques. Third, Establishing experimental infrastructure for understanding electrostatic’s characteristics. Through detailed analysis and expert consultation, a model was created to identify major incident-causing variables. The study then provided a checklist for risk assessment and investigating electrostatic fires and explosions, ensuring a structured approach in industrial settings. Additionally, experimental apparatuses were developed to gather quantitative data on electrostatic behavior, such as how materials like PVC, PE, and PP influence charge buildup, as well as how factors like flow velocity affect static voltage. The study highlights the challenges of investigating electrostatic-related accidents due to the lack of physical evidence and standardized methods. It emphasizes that, while risk assessment and preventative measures currently exist, they are often limited by a lack of detailed data and specialized techniques for electrostatic risk assessment. Therefore, this research provides a framework for improving electrostatic risk management, including better risk assessment methodologies and an infrastructure for empirical experiments to support more accurate evaluation and prevention in industrial sites.
