> Almost nobody doing industrial work with comparable PPE doesn't spend at least 1-2 hours of a typical workday out of the PPE.
Which leaves many thousands of hours in PPE, for many thousands of people. If the N95 masks caused health issues, we'd know. If someone can demonstrate a) a mechanism and b) any evidence for such an effect, I'm all ears.
It does, and I think that's a reasonable argument & comparison, but it isn't the same as the one you were making initially, which is all I'm pointing out.
Almost nobody doing industrial work with comparable PPE doesn't spend at least 1-2 hours of a typical workday out of the PPE.
The linked PDF has an example of a typical workday when removing asbestos, note how many times it involves putting on or taking off the PPE.
I'm not making any claim about COVID mask mandates, other than your examples seeming irrelevant to "chronic, day-in-day-out long term use of N95s".
