This report proposes a risk-factor-based analytical approach for integrating occupational health and safety (OHS) into project risk evaluation. The study addresses the ineffectiveness of conventional risk evaluation methods and the negligence of risk factors impacting worker health and safety. The methodology uses the analytical hierarchy process (AHP) to evaluate OHS risks. A case study illustrates the integration of OHS at an early project stage, allowing for continual reassessment of criteria. The approach emphasizes the importance of identifying risk factors and their relative significance to prevent industrial accidents, capital losses, and environmental destruction. The report reviews existing literature, outlines the methodology, and provides a detailed case study to support the proposed approach for improving OHS in industrial projects.
