  • Patent number: 6955170
    Abstract: A system and method for the remote administration of respirator fit tests are disclosed, along with a system and method for administering qualitative respirator fit tests to two or more test subjects simultaneously. Remote administration of respirator fit tests involves the testing of test subjects located at one facility by a test administrator located at a different facility. The two facilities may be located, for example, in the same city, in different countries, etc. As a result, a single test administrator may, for example, be able to administrate fit tests with test subjects located in a variety of facilities in one day without traveling. Qualitative respirator fit testing systems and methods of the invention include multiple test stations and an aerosol generator system in fluid communication with each of the test stations.
