In our freshman chem labs, we do use concentrated nitric acid (70%), concentrated sulfuric acid (98%), etc. Having seen minor acid burns caused by splashes, I believe that these are corrosive and hazardous enough to warrant lab coats and gloves in addition to goggles. Aprons do not protect the forearms or wrists, which could easily be splashed by these corrosives. Certainly, a small sulfuric acid burn will heal quickly, but I'd prefer that the student not get burned in the first place.
If a lab coat gets splashed with concentrated acid or base, we do soak and wash their lab coat for them, and they have a temporary loaner lab coat. But normal washing is done by the student.
In our lab, students get 2 drawers: 1 for their glassware, and a separate drawer for their PPE. This way their glassware should not contaminate their PPE.
I agree that in the ideal situation, lab coats would be laundered by the college to ensure maximum care. But then of course, every student would need to purchase 2 lab coats, so they could wear one while their other one is being laundered. It would be a very costly practice for the school and student.
