A Hybrid Safety Risk Assessment Framework Integrating Hira and Fault Tree Analysis for Complex Urban Infrastructure

Abstract

Safety in the construction industry remains one of the most widely discussed subjects and continues to be a focus of ongoing research. With frequent accidents occurring at construction sites, it becomes crucial to identify the underlying causes. This paper applies Job Safety Analysis (JSA), Failure Mode and Effect Analysis (FMEA), Safety Performance Monitoring, and Fault Tree Analysis (FTA) to enhance workplace safety in metro rail projects. Various Hazard Analysis and Risk analysis methodologies are used for ranking the risk by knowing its consequence and its frequency of occurrence in the Construction work place. The primary goal is to identify the hazards present in the workplace and evaluate the associated risks using various available methods to create a safer work environment
