> >Are reusable masks okay in lab or only disposable ones because of chemical contaminants?
IČ??m not sure if you are thinking in terms of cloth or paper masks, but I would recommend that any masks that have been splashed on be replaced immediately. Cloth masks present similar challenges as other clothing worn in the lab. Paper masks are not likely to retain fumes, but also wear out fairly quickly. For that reason, new paper masks each class make sense to me.
Good luck to us all!
