초록

Objectives: This study aims to compare the performance of fit test equipment with international standards and to provide essential data for the establishment of national standards. Methods: This study compared the characteristics and performance of three quantitative fit test(QNFT) devices and evaluated their fit factor measurements for various types of respiratory protective equipment(RPE). A total of 1,350 fit tests were conducted on three different sizes of nine models of respirators, including full-face, half-face, and filtering facepiece respirators. The suitability coefficients and accuracy thresholds of each device were assessed through statistical analysis using ANOVA and ROC-AUC. Results: Fit factors measured using three QNFT devices showed no significant differences overall (p=0.547), but variations were observed depending on the type of RPE and device. ROC analysis confirmed that devices B and C exhibited excellent accuracy (AUC > 0.9), comparable to international standards. Despite similar accuracy across all devices, B and C needed higher fit factor thresholds due to differences in sensor sensitivity. Devices B and C required slightly higher cut-off values (119 and 114 respectively) to meet the international standard for device A. Conclusions: These findings underscore the significance of selecting devices based on environmental conditions and suggest that devices B and C can serve as viable alternatives to device A with appropriate adjustments.
