Lots and lots of great comments. Mostly old street clothes, some aprons, those of us who wear glasses pretty much consider that enough, gloves; some do and some don't. It depends on the chemicals and their level of comfort.

The acetone is used in Carbon Transfer as an alternative to alcohol in the sensitizer.

I've had two accidents, many decades ago, the first was from putting marbles in a glass jar to displace air, and the other was a split in a plastic accordion squeeze container. The bottom of the glass jar fell off when I picked it up and the plastic container, which was made for photo chemicals, split at an outside fold and the contents sprayed out. Both times I didn't see it coming.

It's difficult to cover every situation but common sense and appropriate protection seems right.
