We are cautious at the studio where I work. In total there is about 16 people working in the studio. We wet-mop, and spray when cleaning. The guys who fettle some of the bigger pieces dry, work in the spray booth with the extraction fan on. The owner wants to get a specialized extraction table which is quite an ingenius piece of work. The woodworking factory next to us use these for sanding work. (sucking the dust down into the table, from where it is sucked out of the building.)
But on the whole, I agree with the others. I live in Africa. It is dusty. I grew up in a small farming community and dirt was part of my staple feed, so to say. I am also a RN, and my whole family is all in the medical field. For that reason I do not use antiseptic soaps and cleaners in my house. I do not buy into the hype of using sanitizers, etc. And I might get a mild cold once a year, if that much.
