...or i could have worked in a few trades that oft use masks and respirators and never heard anyone complain about lightheadedness, nor experienced it myself when using such equipment. that, and having gone through several levels of OSHA training and not once hearing any instructor or textbook call for supervisors to be alert for signs of oxygen deprivation in relation to masks or respirators.
nor were any such warnings or cautions issued when going through military NBC training, which require the use of even more restrictive masks and filtering.
the 40 minute guideline you're referring to relates to pathogen growth on the mask; not O2 interference.

What will be with them, if they will complain or deny wearing mask? You will allow them to work without that stupid cloth masks or will provide normal respirators? Will they tell you that they become dumber working in masks? Or may be they allowed to protest against masks?
You can't even imagine how ridiculous your arguments look like.
Especially that sentence:
masks or respirators.
where you mix completely different devices with completely different principles of work, different airflow and so on.
and having gone through several levels of OSHA
I don't give a single fuck about that OSHA (what the fuck is this?) against real oxygen sensor and my own eyes.
Seriously, do you really compare some shitty bureacracy with real measurements? If you are not aware, when here comes instrumentation, bureaucracy could GTFO instantly.
Oxygen level under the mask, that planet was forced to wear, is below the safe limit for humans. There is nothing to discuss at all. And unlike with bureacracy, you absolutely don't need to believe me or anybody else, because you could easily measure it by yourself. Did you check it by yourself?

It's both. Also, O2 interference forces timeout between putting next mask, to allow a human to restore O2 level.
