A Comparison of controlled negative pressure and aerosol quantitative respirator fit test systems by using fixed leaks / Clifton D. Crutchfield, Richard W. Murphy and Mark D. Van Ert
Sumario: An automated version of a new method for quantitative respirator fit testing by controlled negative pressure was compared with a computerized aerosol fit system. The controlled negative pressure technique eliminates many of the problems associated with aerosol and pressure decay fit test methods. A series of fixed leaks was used to compare the leak measurement capablities of the controlled negative pressure system against a standard computarized aerosol fit test system
