This paper presents an in-depth analysis of a liquid hydrogen (UN1966) tanker accident that occurred on October 23, 2017, in Niagara Falls, NY, USA. Utilizing Quantitative Risk Assessment (QRA) methodologies, specifically the ALOHA (Areal Locations of Hazardous Atmospheres) modeling tool, the study evaluates the toxic and flammable threat zones created by the hydrogen vapor cloud resulting from the tanker collision. The incident's emergency response and its effectiveness in mitigating potential disasters were examined. Key lessons and preventive strategies were identified, emphasizing the importance of robust risk assessment, continuous monitoring, public awareness, and effective emergency response planning. The findings underscore the critical role of advanced QRA techniques in enhancing industrial safety and managing hazardous chemical incidents.
