| Abstract |
There are on the market in Japan 2 types of dust respirators complying with Ministry of Labour standards: replaceable-cartridge dust respirators and disposable dust respirators. According to the provisions of the standards, a replaceable-cartridge dust respirator is required to provide a device which enables the wearer to check the facepiece-to-face fitting easily at any time, but a disposable dust respirator is not required to have such a check system. A Mask Fitting Tester was developed and the results of tests using it are reported. The Tester includes a particle counter that can count the number of particles with a diameter greater than 0.7µm. The Tester quantitatively and easily tests mask fit. The measurement can be done without modifying the dust respirator and takes about 1 minute. Tests conducted with the newly developed Tester gave penetration rates of more than 10 percent for several disposable dust respirators even when the subjects had fitted them carefully. |
