Abstract

Road transport in India faces significant challenges with hazardous materials (hazmat) transportation, particularly in densely populated urban areas like Kochi, Kerala. This study addresses the critical need for establishing safety and survival margins during potential chemical transportation accidents. Focusing on four hazardous chemicals commonly transported by road - ammonia, chlorine, benzene, and hydrogen chloride - the research employs advanced modeling techniques to determine safe distances during potential chemical release scenarios. The study applies and refines the concepts of’safety margin’ (where individuals can remain up to one hour without irreversible health effects) and’survival margin’ (minimum distance to prevent fatalities) in the specific context of hazardous materials transportation in urban road networks. Using the Chemical Exposure Index (CEI) and ALOHA® software for consequence modeling, the research analyzed toxic chemical dispersion under worst-case full-bore rupture scenarios. Key findings indicate that hydrogen chloride poses the highest level of danger, with a possible lethal radius of 1,540 m determined by LC1 concentrations. The study recommends a minimum 1.5-km evacuation radius during hazmat transportation incidents and emphasizes the importance of public awareness and emergency response planning. The research provides crucial insights for improving road safety, emergency preparedness, and risk mitigation strategies in urban transportation contexts, with implications for policy development and public safety protocols.
