| Abstract: | It is most important to establish the statistical indicators of occupational hazard in workplace tot comprehensive evaluating and setting up supervision strategy. Based on evaluation collection over 30 experts in safety science, 65 candidate indicators were screened by the variation coefficient method, correlation coefficient method, principal components analysis method and Systematic Cluster Analysis. 33 ndicators were selected, which could evaluate the status of occupational hazard. |
