An interesting comment in the original link by a poster saying, essentially, "all the safety captains and meticulously memorized safety code rules, useless when something actually happens".

I can attest to that feeling. A number of years ago my car engine caught fire while it was parked at a camp. (The running theory is that a rodent chewed through enough wiring to cause a short). There was a good few moments of "uhhhh what's happening?" followed by, in that moment, not having a clue what to do.

That moment led to writing down a specific procedure "in case of fire", that is printed and posted in every building. It is unambiguous. Step 1, this person do this. Step 2, everyone else do that.
