You do not try to debug the fire. There are people who are good at not dying while trying to do that. You are not one of them.
You do not try to avoid Big Red Buttoning because your bosses are idiots and they might come down on your hard for it: while your bosses are probably idiots, the first thing they'll tell you about Big Red Buttons is that nobody has ever gotten fired for pressing the Big Red Button, because everyone agrees that Big Red Buttons exist to get pushed and you never want to not have it pushed because someone was worried about getting fired. Big Red Buttons are costly affairs, sure. That's why we have redundant systems, insurance, and other various things that suggest we're responsible professionals.
