This has "dont wear your seatbelt or wear condoms" energy. It never made any sense to argue that point there and it doesn't make sense here either. Wear your lab coat and goggles or you're going to be kicked out of labs until you grow up.
lab coat or nitrile gloves for that matter aren't supposed to make you safe, lab coat is supposed to give you enough time to run to shower if something really bad happens. if you're looking for protection from everything you need something much more substantial
