“…This finding is very similar to those published results obtained from American 10) . From these findings, the statement that female body measurements average 92 percent of male body measurements can be applicable to Koreans, too.…”

“…This finding was very similar to those of Gross and Horstman 10) . Although their findings were based on half-masks, they found that when any two brands (in multiple size) of half-mask respirators were available, 95 percent of both men and women could be safely fitted.…”

“…The results of facial length dimensions measured in this study were generally similar to those reported in other Korean studies 1,12) . However, most facial dimensions measured on this Korean population 1,12) were found to be significantly different from corresponding dimensions in other Caucasian ethnic groups 4,[8][9][10][18][19][20] including face width, lip width, nose width, and nasal root breadth. These comparisons revealed that, regardless of *All measurements for males were significantly higher than those of for females (p<0.001) by two sample t-test except NRBR.…”

“…But several studies 4,5,10) have reported that the facial dimensions used for half mask design showed no relationship to the fit performance of half masks. Confounding the problem is the fact that the data were originated mainly from military personnel, where variability in terms of age, weight, and height might have been much less than that of civilians.…”

“…A review of literature revealed that only a limited amount of research on other ethnic groups including Blacks, Hispanics, and Asians have been done [6][7][8][9] . Some of these studies indicated that ethnic and racial groups were afforded a lower level of protection than Whites 9) and that these groups may have a significantly more difficult time obtaining an adequate fit with any given brand of respirator 10) . In Korea, two studies 1,11) have been published comparing the performance of domestic respirators to those of imported ones.…”

Past studies on respirator fit or performance have mostly been done for Whites or male subjects, and little attention has been paid to minorities and Asians. To fill this gap, this study was designed to provide facial anthropometric data for Koreans and to analyze the association between facial dimensions and respirator fit factors for three brands of quarter-mask respirators, two domestic and one imported brand, using a Portacount™ 8020. A total of 110 university student subjects, 70 males and 40 females volunteered for participation in the study. The results of this study showed that Korean males and females have different facial dimensions as compared with those of White males and females. Unexpectedly, the imported respirator performed better than the domestic respirators. Males were found to achieve better respirator fit than females regardless of respirator brands tested. The regression analysis found no common prognostic variables with the three respirator brands studied. A stepwise logistic regression analysis was conducted to find predictive facial dimensions with respirator fits. Some facial dimensions were found to be statistically significant, but these dimensions are different from the traditionally recommended facial dimensions of face length and lip width for quarter mask. To improve respirator fit for Koreans, these different facial characteristics need to be considered in the design of quarter mask respirators.

A respirator is an enclosure that covers the nose and mouth or the entire face or head. Respirators can have two general types of fit: (1) tight-fittingthat is, quarter masks, which cover the mouth and nose; and half masks, which cover the face from the hairline to below the chin; and (2) loose-fitting, such as hoods, helmets, blouses, or full suits that cover the head completely. There are two major classes of respirators:(1) air-purifying to remove contaminants from the air, and (2) atmosphere-supplying to provide clean, breathable air from an uncontaminated source. As a general rule, the latter-type respirator is used for more hazardous exposures.

To evaluate the qualitative fitting characteristics of FFRs on Iranian people. 62 participants were fit tested qualitatively by four brands of FFRs, including three imported (A, B, and C) and one domestic (D). The respirators were assigned to the participants randomly based on the Latin Square design (LSD) using the Moldex® Bitrex® Fit Test Kit. R 3.2.5.0 software was used to analyze the data. Among the respirators, A and C respirators had the lowest and highest fit test passing rates with 1.60% and 43.50%, respectively. The majority of the participants had medium face sizes (45.20%) and small and long/narrow shapes (32.20% and 32.30%). There was a significant difference between the passing rate of domestic (D) and imported (C) respirators (p value<0.001). Factors including respirator brand, style, and gender had significant effects on respirator fit (p value<0.01). There was a low fit test passing rate of the studied respirators among participants. Furthermore, 19.40% of the participants fell out of the NIOSH fit test panel. Therefore, it is required to develop a unique bivariate fit test panel and design the respirators based on the Iranian facial dimensions. Meantime, manufacturers need to provide various sizes and styles of the respirators to provide adequate respiratory protection for the users.
