No no, please don’t do this without eye protection. I did some grinding without eye protection, didn’t hurt or anything, but day later doctor had to drill metal particles out from my eye balls.
0/10, would not recommend
and they said that I cannot get MRI ever again, because some small particles might be still inside and magnet can pull them out. Fun stuff.
I work at electricity distribution, can confirm, we never have any issues, it is evil spirits, not us.
