Title Effect of leak location on measured respirator fit
Bibliographic information June 1997, Vol.58, No.6, p.413-417. 15 ref.
Abstract In a study to assess how well current respirator fit-test systems detect leakage, known sources of leakage were introduced at three fixed locations on half-mask and full-face respirators mounted on a headform-breathing machine system. Fit-tests were performed with an ambient aerosol system and a controlled negative pressure (CNP) system. The ambient aerosol system detected an average of 37.2% of the known leakage; there were significant differences in leakage measurements as a function of leak location and mask type. The CNP system detected an overall average of 97.9% of the known leakage; results were not affected by leak location or mask type.
