That wouldn't surprise me in the least. Where I work every employee is required to wear one of those blue surgical masks. One girl wears a bandana over her face. And that is even more worthless than the mask.
The only problem with that is those masks do nothing at all to prevent someone wearing them from contacting Covid 19 since the virus is so small it passes thru the weave of the mask like it isn't even there.
But don't tell that to our wonderful supervisors. The Secretary parades around wearing one and thinks she is so safe and protected.
Nothing could be further from the truth.
What we all need are the N-95 masks they wear in the area they cut fiberglass to keep those microscopic fibers out of the lungs.
This is the same situation as Asbestos contamination in older buildings. ;)
