Quite some time ago I stopped asking if I should do this or that.
I figured that I knew what was going on, and if it needed fixed I would fix it. I also figured if someone didn't like that, they would let me know. If I want to shut something down, I shut it down, lock it out, and tag it. I have never had anyone complain or question me about it.
Now then, on the other hand... you do have to use your head for something besides a hat rack. As BillSnuff said, there is an obligation to make some production. That is what everybody's there for, and what pays the bills. Your bosses need to know that you are cognizant of that .
You need to be experienced and familiar with the process, and how what you're doing affects other phases of production, which it almost always does... If what you're doing is in a vital area, or an area that is not so urgent.
I hear a lot of stuff blamed on water, that I don't know if that's what it really is or not... How long does it take to blow an air hose through whatever it is? Does this thing have an EGC?
If something that people need to use and touch, is shocking them, I'm shuttin' it off and locking it out. I can't imagine anyone giving me any static about it.... but I'm also pretty much elbows and butt holes getting it fixed, and running again.
