"It's easy to not touch your face when you are wearing rubber gloves (and a respirator). It's hard to not touch your face 24/7."
Rad folks do the shoulder to face rub....
it depends on where the cameras are, or are not,....
there's the "put clean skins on over the rubbers, then reach under the hood, grab the top of the coveralls and wipe the face with the upper inside portion of the coveralls",...
really, really way off any expectations,.....
and yet, it seems to work without any cross contaminations?!??!??
when down with deliberate, well executed, motions,...
but this could go on for a really long time and go WAY off topic,...
