6. It depends on material, if I'm working with wood then I probably won't. Metal yes. I also wear glasses so depending on available safety glasses, they may provide no additional protection (the safety glasses may not sit flush against my face because of their design). Metal working is usually done in a shop where they require safety glasses, but sometimes outside of the shop, I wear safety glasses ~70% of the time.

Edit: If there are students around, I will wear safety glasses to set an example. I'll admit I have bad habits.
