Were in the hen house. A rabbit and a moose was playing in the barn. Some sponges soaking in the sink. How many farmers will it take to get a horse on top of an elephant over the moon?
It shouldn't ruin your makeup. Since only the edge of the safety goggles touch your face, when you remove them, the only thing that's evident should be a few lines on your face, and that's it. To fix that, you don't need to reapply your makeup or anything like that; just blend it in with your fingers and the lines will go away. As long as you have your phone or a compact mirror, that in itself only takes like 2 seconds, so you certainly don't need to run to the bathroom between periods.
There's a reason you need those goggles. Your safety is more important.
Just be careful, they should only cover a small ring around your eyes. See if you can finish early and go to the bathroom, and just make sure there aren't any harsh lines where the glasses were. You should be able to blend rather than re-apply.
wear less foundation powder. not only does that make your face look cakey, but since there are so many layers of makeup on, the goggles cut into the thick layer of foundation you have on.
Mark R is pretty close to correct but I would like to point out that stainless steel flanges have a lower pressure rating than steel flanges so the 285 psi he quoted is not correct for a stainless flange.
