| Abstract |
A study was carried out to assess how well a controlled negative pressure (CNP) fit-test system and an ambient aerosol fit-test system could measure known sources of leakage into a respirator. In repeated measurements of respirator fit for five subjects, the CNP system's measurements of leakage averaged 105% of the known leakage rate (mean coefficient of variation 10%). The ambient aerosol system detected an average of 21% of the known leakage (mean coefficient of variation 62%). The CNP system measurements were substantially more accurate than those reported by the ambient aerosol system. |
