fire safety system failures in the plasco tower collapse: a case report on regulatory gaps in tehran’s high-rise buildings

Background: on january 19, 2017, the plasco tower, a 17-storey commercial building in tehran, iran, caught fire and collapsed, resulting in 36 deaths, including 16 firefighters. the tragedy revealed major deficiencies in iran’s building safety regulations and emergency response systems. by analyzing this catastrophic event, this report contributes a template for assessing the preparedness of urban environments under stress and identifying regulatory blind spots that can lead to preventable disasters.methods: this case report draws on official investigation documents, eyewitness testimonies, fire department records, and structural engineering assessments. a regulatory review compared iran’s national building regulations (2019) with international standards from nfpa, the european union, and japan.results: three primary contributors to the disaster were identified including flammable polyethylene cladding, unregulated structural modifications, and systemic failures in emergency response. regulatory comparison highlighted gaps such as the absence of facade fire performance requirements, weak inspection protocols, and insufficient public preparedness.conclusion: the plasco tower collapse illustrates systemic vulnerabilities in urban fire safety governance. the findings underscore the urgent need for reforms in material certification, enforcement mechanisms, and inter-agency coordination. practical, phased recommendations are proposed for retrofitting, safety verification, and emergency planning, with implications for high-risk urban settings in iran and similar contexts.
