I've worked in two safety-critical industries (aircraft flight operations, and spacecraft engineering and operations). Everyone is explicitly encouraged to raise any safety concern at any time, and no one is punished for being wrong. It is better to be late than dead.
This is a required element of a robust safety culture. If you ever find yourself in a situation where this is not the case, you are in a poisoned culture that will eventually hurt or kill someone, and you should do what you can to change it and/or leave.
I previously worked in an Exxon owned chemical plant. Everyone on site from ditch digging sub contractors to Exxon employee plant manager was empowered to stop work if they thought there was a problem.
