I'm wondering how I could set a primer off in my press. I've managed to crush a few, put some in upside down, and some in sideways. But I have never had a primer detonate.
I try to keep my press clean and in good working order. I also understand completely the operation of my press. I don't know, but maybe it helps.
In reguards to the noise, I have heard a few hundred gun shots and still have outstanding hearing.
With all that said, I protect my eyes and ears all the time when shooting and my eyes when reloading. Those are just good shop rules.
