Development of a dichotomous-flow quantitative fit test for half-mask and full-facepiece respirators / Usha Krishnan... [et al.]
Sumario: This article starts with a discussion of the relationship between pressure drop and cartridge flow rate for some of the cartdriges commonly used in the workplace. This is followed by a description of the "dichotomous-flow respirator fit test" that has been developed for quantitatively fit testing field-use respirators fitted with cartridges to be used in the workplace. Finally, the performance of the new test is compared to that of the aerosol fit test
