Abstract: With a view to improve health and safety of human resources in industry, the study aims to identify and evaluate the occupational hazards relevant to cement industry in China. Primary data were collected from the cement industry professionals based on physical, chemical, biological, process, and ergonomic and environmental hazards. The Dynamic Grey Relational Analysis (DGRA) was used to identify and rank the hazards. This method established an effective system to handle complex relations together with uncertainties found in occupational hazard information. For comparative analyses, the Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS) and the Grey Ordinal Priority Approach (OPA-G) were used. We found that the most significant hazard was physical cement dust in all methods. The Kruskal-Walli’s test (KWT) was also applied to investigate the significance of this hazard across different demographics groups, and found no significant differences among them. This study is the first of its kind to apply the Grey Relational
Analysis methods to explore the occupational hazards of airborne contaminants in cement industry of China. This suggests the industry stakeholders to develop effective safety measures for the cement industry by correct identification and control of key hazards.
