Lies? What lies?
Let's start with his first claim.
"Don’t agree? Argue with the experts at OSHA, which is the main US agency, i.e., its Occupational Health & Safety Agency. These masks are meant to be worn only for short periods"
I have yet to see any evidence that experts at OSHA say "These masks are meant to be worn only for short periods" or words of that effect.
I have every reason to believe that is a lie.
Although neither of the two OSHA comments below directly say the contrary to that, they do hint OSHA would;
https://www.osha.gov/Publications/OSHA3079/osha3079.html
"...Users must not alter or remove the respirator even for a short time, even if it is uncomfortable..."
-that's for respirator, not a face mask, but it would seem strangle inconsistent if they didn't say the same thing for face masks.
https://www.osha.gov/Publications/OSHA3990.pdf
"...PPE will have to be used repeatedly for a long period of time..."
-it is difficult to interpret the exact meaning of the above assertion but that above assertion can be interpreted as suggesting the contrary of "These masks are meant to be worn only for short periods".
So, That makes me think he is probably just lying.
This seems to be confirmed by;
https://www.sabhlokcity.com/2020/10/some-unverified-info-on-masks-from-facebook/
"...Some unverified info on masks from Facebook..."
And if you look down it lists his claim of OSHA saying "These masks are meant to be worn only for short periods" as being "UNVERIFIED". Strange that, don't you think?
Sorry, obviously fake news that fools no scientist or science expert here. Try again.
