I was at San Quentin from 80 to 90, then at Solano (Vacaville) from 1990 to 2013. We called it getting gassed. It never happened to me, but I came close to getting it a few times. I did have a partner, that got gassed in the eyes, nose, and mouth in early 2013. It was not good. I wore face protection after that incident. Not all did, but I figured no one could protect me better than me.
Good for you. I think that was smart of you. Why take the chance.
