Difference Between Qualitative And Quantitative Fit Test. The last 10 years in the State of Minnesota have especially seen the majority of fire de-partments turn to annual firefighter physicals and respirator fit testing. There are two types of fit tests that can be performed as part of the respiratory protection program. AUTOMATIC RECORDKEEPING The PortaCount Respirator Fit Tester supplies objective testing data recorded automatically and easy to share. Quantitative fit testing I mentioned to a fire chief the other day how medical services for fire de-partments have changed since Med Compass began in 1985.

OSHA specifies approved procedures for both qualitative fit testing QLFT and quantitative fit testing QNFT. This video briefly discussed the difference between quantitative face fit testing and qualitative face fit testing. Qualitative tests rely on the wearers taste response to detect faceseal leakage of a test agent Bitter or Sweet. Fit tests are either quantitative or qualitative. There are several methods of QNFT some involve measuring the concentration of an aerosol challenge agent both inside and. Qualitative fit testing is a subjective passfail test method.

There are two different methods of respirator fit testing. We choose to use the TSI Portacount Pro when performing this method of testing. Qualitative fit testing is a passfail test to assess respirator fit based on the individuals response to a test agent. OSHA allows for the use of both qualitative and quantitative tests to evaluate a respirators fit on an individual. However previous studies have indicated that fit-test results may differ between QLFT and QNFT and that the outcomes may also be influenced by the type of respirator model.

OSHA specifies approved procedures for both qualitative fit testing QLFT and quantitative fit testing QNFT. Fit tests are either quantitative or qualitative. Below is a summary of the two types of fit tests as described by OSHA. The qualitative fit test is normally used for half-mask respirators. An unsuccessful qualitative fit test QLFT or quantitative fit test QNFT would indicate that the respirator has not achieved a good facepiece-to-face seal for the worker being tested and the respirator would therefore be expected to deliver less.
