Comparative study on fit test procedure of disposable facepiece
To popularize the fast fit test method,aiming at the key problem that whether there is significant difference between the fast fit test procedure approved by the United States Occupational Safety and Health Administration(OSHA)and the standard fit test procedure,based on the condensation nucleus particle counter fit test method,three types of disposable face-piece were selected.Based on the self-built face database,222 sets of comparative test between the standard fit test procedure and fast fit test procedure were conducted,and the Friedman test,chi-square test,Spearman correlation analysis and Wilcoxon signed rank test were performed on the experimental data.The results show that there is a significant positive correlation be-tween the passing rate of standard fit test and the passing rate of fast fit test,and there is no significant difference between the fit results of standard fit test procedure and the fit results of fast fit test procedure.The research results can provide reference for the development and revision of the fit test standard of respiratory protective equipment.
