Why Do Nurses Have to Wear 3 Masks?
I saw a video of a nurse (I think he was a nurse but I could be wrong as to what his specific job is in the hospital) showing everything he has to wear at work, like scrubs as well as 3 different type of face masks. Is there a specific reason why 3 masks are needed or is it simply for extra protection?

I don't know. One for each crack?
