Workplace safety remains a global concern, with millions of occupational accidents occurring annually. Industry 4.0 (I4.0) introduces IIoT, Digital Twins, Cyber-Physical Systems, and wearable devices that can enhance workplace safety by enabling real-time monitoring, predictive analytics, and automated risk mitigation. This study proposes a preliminary conceptual Workplace Safety 4.0 Framework that integrates these technologies to proactively reduce accidents, improve operational resilience, and promote sustainability. A systematic literature review identified key technological contributions, highlighting IoT as the most widely implemented solution, followed by Augmented Reality AR, VR, CPS, DTs, and blockchain. The proposed framework addresses existing gaps by offering a structured, scalable approach applicable across multiple industries. The findings demonstrate that integrating I4.0 technologies enhances safety, reduces operational disruptions, and fosters a safer and more efficient work environment. Future research should explore AI integration and sector-specific applications for further advancements.
