This study presents a comprehensive examination of contemporary approaches to enhancing reliability and safety within industrial power distribution systems through the coordinated application of selective coordination principles and arc-flash risk mitigation strategies. The primary purpose of the study is to critically explore how these two traditionally separate objectives can be systematically integrated to address the growing complexity, safety demands, and operational expectations of modern industrial electrical networks. The study adopts a structured review methodology, synthesizing established theories, international standards, analytical techniques, and empirical evidence from practical implementations across diverse industrial contexts. Core areas of analysis include the fundamentals of protection coordination, the physical and analytical understanding of arc-flash phenomena, hazard assessment and risk evaluation methods, mitigation strategies, and the role of emerging digital protection technologies. Particular attention is given to lessons derived from industrial case studies and applications in both developed and emerging economies, highlighting context-specific challenges and solutions. The findings reveal that selective coordination and arc-flash mitigation are intrinsically interconnected through protective device behavior, fault-clearing performance, and system configuration. When addressed in isolation, these objectives may conflict; however, integrated analytical workflows and advanced protection technologies enable balanced solutions that preserve system reliability while significantly reducing arc-flash exposure. The study further demonstrates that engineering controls, supported by adaptive and digital protection systems, offer the most effective and sustainable risk reduction, while administrative measures and personal protective equipment serve as essential complementary safeguards. The study concludes that an integrated, system-oriented approach represents a mature and necessary evolution in industrial electrical design and operation. It recommends the adoption of coordinated protection and safety studies, investment in digital protection infrastructure, periodic reassessment of system conditions, and targeted capacity building. These measures collectively support safer, more resilient, and operationally efficient industrial power distribution systems.
