Occupational Safety and Health (OSH) training has emerged as a key component in fostering workplace sustainability by promoting safety, health, and environmentally responsible practices. This study explores the role of OSH training in driving sustainability by examining its influence on employee awareness, behavioural change, and organizational policies. The conceptual framework developed in this paper highlights how OSH training contributes to sustainability goals through mechanisms that enhance workplace safety while aligning with environmental and social responsibility initiatives. Despite the potential benefits, challenges such as organizational resistance, resource constraints, and regulatory complexities hinder the effective integration of OSH training with sustainability. This study also discusses theoretical, practical, and policy implications, emphasizing the need for regulatory support and strategic organizational commitment. Future research should empirically validate the proposed framework through longitudinal studies, cross-industry comparisons, and qualitative investigations into employee and managerial perspectives. By embedding sustainability principles into OSH training programs, organizations can enhance employee engagement, improve compliance with sustainability standards, and foster long-term resilience. This research contributes to the growing literature on workplace sustainability by integrating safety training into broader environmental, social, and governance (ESG) strategies, offering insights for both academia and industry.
