Page 8: Safety & Environmental
The QuantiFit2 does not trap air in its system either before, during or after a fit test. The QuantiFit2 does not push air into the mask. The QuantiFit2 pulls air away from the test subjects mask and vents it out of the system. - Page 9 EPA approved disinfectant as these have been shown to efficiently inactivate over 99% of microorganisms (to include COVID-19) within a minute. The adapter should be dry before use in a fit test. The QuantiFit2 tubing should be carefully wiped down with an EPA approved disinfectant.

Page 10: How The Quantifit2 Works
When the challenge pressure is reached, if there isn’t a leak, the QuantiFit2 doesn’t remove any more air from the respirator. If there is a leak, air enters the respirator. The QuantiFit2 then removes air from the respirator until the challenge pressure returns to the targeted value. This process continues for 8 seconds, and then the test step ends. - Page 11 FF1 = The fit factor for the first exercise; and FF2 = The fit factor for the second exercise; and FFN = The fit factor for the nth exercise Chapter 2 | How the QuantiFit2 Works | Fit Factor Explanation...

Page 54: Chapter 20 Troubleshooting
When the traceline does not lift above the bottom of the graph, this indicates that there is a large leak between the QuantiFit2 and the person wearing the respirator. This would be related to a leak in the integrity of the respirator, a poor donning, or poor fit of the respirator. - Page 55 Failure to reach challenge pressure Like the large leak, when the traceline does not reach the challenge pressure line, this indicates that there is a moderate leak between the QuantiFit2 and the person wearing the respirator. 1. Check all connections for proper attachment.
- Page 56 Traceline way above challenge pressure line The QuantiFit2 traceline goes opposite of the direction of the pressure. If the line is above the challenge pressure line, that means that there is too much negative pressure. In this case, a test subject is most likely sucking in a breath during the test.
-
Page 57: Failing Fit Factors
When fit factors are consistently low, the respirator may be a poor fit for that person. If the graph looks normal and the fit factor is low, that means that the QuantiFit2 is successful in meeting the challenge pressure, but a large volume of air is required to be removed to achieve that targeted pressure, which means the leak is too large. -
