Author information

2014 Volume 90 Issue 2 Pages 53-64


In this study, we evaluated the total leakage rate of a newly developed foldable type disposable mask before and after the instruction about the method to wear it. Eleven people without previous experience of wearing the mask and one person with the experience of wearing it attended the instruction session. We also examined the typical mistakes observed from the unexperienced people in wearing the mask. The measurement of the leakage rate was conducted by means of the Mask Fitting Tester Model MT-03TM, Roken type, in accordance with the quantitative fit test procedure established by the United States Occupational Safety and Health Administration. After training about how to wear the mask, reduction in the leakage rate was observed. The instruction including the mask fitting process had a significant impact on the leakage rate more notably than in the case of instruction about wearing operation alone. The typical mistakes observed while wearing the mask included inability to open the foldable mask correctly and improper adjustment of the headband.
