ABSTRACT:
A device for fit testing facepiece respirators is presented. In accordance with the present invention, a testing probe is installed in the facepiece of a respirator during fit testing. In a first embodiment, the probe of this invention is installed in the front or side port of the facepiece after the filter element, valve or breathing tube assembly has been removed. The probe comprises a threaded plug adapted for installation into the front port of a respirator and a male hose connector mounted through a hole located at about the center of the plug. In a second embodiment of this invention, a fit testing probe is installed in one of the side or front ports of the facepiece respirator after the exhalation valve or filter element assembly has been removed therefrom. In this latter embodiment, the probe comprises a spool shape plug adapted for installation into the side port. Again, a male hose connector is mounted to the plug through a hole located at about the center of the plug thus providing a probe for fit testing a facepiece.
