Yeah all that online WHMIS and H2S Alive training kept people safe. That's the stupidest thing I've read all week, and that's over and above JCL's original comment.
You're missing the point. Let me use 2 of my last few times underground as an example. I've managed to catch two different crews during their fire drills lately. You've got ~75 people underground at ant time, and maybe 20 vehicles scatter through the mine. Everyone pitches in, picks up anyone they are near. Checks in to make sure no one is left behind. All this while you can't smell anything other than stench (the same compound that is used to put the roten egg smell in natural gas, only concentrated so that it can disperse into all areas of the mine without being so diluted that you might miss it) Easy to see how people who practice this sort of thing regularly would react that way outside of work.
With mine rescue, I've been under oxygen and gone into smoke filled courses to practice for situations where we have to go into the mine, mill, shop, etc when the smoke is so thick you can't see more than a few inches.
We train for the worst so that everyone gets to go home and see their families every night. We look out for each other.
That's the problem with cities, they're refuges for the weak, the fish that didn't evolve.
I don't want to google this - sounds like a thing that NSMB will be better at.
