n this study we proposed a semi-quantitative exposure risk assessment model, Exposure Hazard Index (EHI), to access the potential chemical exposure risk of workers in various occupational environments. The model was applied to two national-wide workers? chemical exposure databanks, which were established in 1996-1999 and 2006-2009, respectively, to examine the change in various industrial hygiene measures national wide during the above two periods of time. Results show that potential chemical exposure risks had been significantly reduced. The top two major causes for the reduction of the exposure risk were the ?reducing exposure time? and ?conducting more effective industrial hygiene management system?. Nevertheless, results also show that ?application of effective engineering control strategies? was slight deterioration. The above results suggest that the governmental industrial hygiene inspection should focus more on the installation of engineering control devices of industries, rather than on management issues. In conclusion, using the semi-quantitative exposure risk assessment model could not only be used for accessing the potential chemical exposure risk, but also could serve as a tool for identifying the exposure hazard factors which should be improved. The information is useful for both industrial hygienists and the government agencies to assess the effectiveness of the adopted industrial hygiene control programs and to initiate an effective strategy for the abatement of workers? exposures.
