Topic of Lecture: Occupational health risk assessment methodology in workplaces


Abstract: There has been a very difficult task for occupational disease prevention in China. Occupational health risk assessment (OHRA) is an effective tool for controlling occupational health risks. Nowadays, China still lacks a complete standard system or methodology for OHRA. We aimed to review the international occupational health risk assessment (OHRA) methodologies and their preliminary application in China, and to carry out comparative studies between different models. Six models, including quantitative (e.g., from the United States EPA), semi-quantitative (e.g., from Singapore), and qualitative (e.g., from Australia, Romania, the International Council on Mining and Metals, and the Control of Substances Hazardous to Health Essentials) methods, were selected for qualitative and quantitative comparisons. Each model has its assessment principle, strengths, and limitations. All of them had a potential to identify the critical points of occupation health risk in various industries. The EPA and COSHH models were more likely to obtain higher risk levels than other models and appeared to be a relative independence. The Singapore model had a good compatibility with other models. Combined application of different types of OHRA models including quantitative, semi-quantitative, and qualitative methods could be a part of workplace OHRA strategy. Further comparative studies of different OHRA methods in key industries should be conducted in developing countries.
