andy i have worked in hospitals and in other places where there are other nasty stuff. i know what the minimum ppe's one needs to wear. anyone who tells you wearing a sloppy rag that you just pulled out of your pocket, over your nose and mouth (and reusing it over and over again) is good enough is lying though there teeth. i not only would be fired on the spot. i would be banned from ever working there again. you would need to not only be required to wear a properly fitted mask that was made just for a certain purpose you would need to be wearing a full suit (with booties/ face shield and something over the head. not only that but they had to keep a negative air pressure in the room. and when you came out
you stripet, and showered. to get back you needed to get all fresh ppe,s nothing was reused. i could go on but i'm tired of typing
but your a smart guy i'm sure you get the point.
