Document: Both subjects were able to taste the saccharin solution immediately (< 5 seconds of exposure) as a sensitivity test and the test was continued for each respirator. Cotton cloth was fit loosely over subjects' face and surgical mask was fit according to manufacture instructions to hook elastic around the back of the ears. Neither the cotton cloth nor the surgical mask was able to obtain a qualitative fit (Figure 3) : Both cloth and surgical mask failed qualitative saccharin solution fit test within 15 seconds of initial exposure and no additional testing was taken. Surgical mask was tested repeatedly to ensure this was not a false result. On average, sweet taste was detected within 45 seconds with a surgical mask or cotton cloth.
