WRH Fit Test Demonstration

You mentioned “heat and moisture coming from the nose piece is normal” when testing seal. Does that mean glasses fogging a bit when wearing this mask it okay?

There's a lot of good info here, but it's too bad to see the skipped steps and shortcuts. The instructions that come with the 3M fit test kit used in this demonstration expressly say to apply no less than 10 squeezes on the nebulizer (not 4), it also says to do each excercise for 60 seconds (not 30) and the last excercise needs to be more strenuous than simply "walking". The subject should repeatedly bend over and stand up or jog in place for 60 seconds (again, not 30). I know it's challenging to achieve a successful fit using an N95, but resorting to shortcuts and posting this video as a reference to others is quite concerning.

Some qualitative fit testing protocols only require 30 second exercises. This video is from Canada and is not subject to the OSHA standard for qualitative fit testing. I'm not familiar with the range protocols used in Canada, so I don't know how to judge this fit test's compliance with Canadian standards.
