Industrial Hazard Identification and Automated Safety Control Systems: A Comprehensive Review of Industry 4.0 Technologies, Artificial Intelligence, And Future Safety Paradigms

Industrial environments are characterized by complex interactions among human operators, machinery, materials, and information systems, creating diverse safety challenges. Conventional safety management approaches predominantly rely on periodic inspections, manual monitoring, and reactive intervention strategies, which often fail to provide timely hazard detection and rapid emergency response. The emergence of Industry 4.0 has fundamentally transformed industrial safety management through the integration of cyber-physical systems (CPS), the Industrial Internet of Things (IIoT), artificial intelligence (AI), machine learning (ML), digital twins, and automated control technologies. This review presents a comprehensive analysis of industrial hazard identification and automated safety control systems by synthesizing research published between 2013 and 2026. The study examines industrial hazards, enabling technologies, communication architectures, intelligent analytics methods, and automated response mechanisms. Furthermore, it explores the role of Safety 4.0 and Industry 5.0 paradigms in promoting human-centric, sustainable, and resilient industrial operations. Key challenges related to interoperability, cybersecurity, data quality, scalability, ethical concerns, and workforce adaptation are critically evaluated. Finally, future research opportunities, including explainable artificial intelligence, digital twins, immersive technologies, and autonomous safety systems, are discussed.
