Our chemistry teacher warned us about this stuff. She told us that if you get it on you, don’t hesitate to call out immediately because you will not feel anything and think you’re okay until it’s too late and under your skin. And then it burns.

Hey, you wanna fight fascism, you gotta get some PPE. Plain-as.
Time and resources wasted ain’t nothing and you can spray the foam from a bit of a distance.
