He wouldn't be thinking "I'm going to die if I don't leave now", he'd be thinking "when I survive I will need this".
I think that's actually really insightful as to what goes through many people's minds in an emergency evacuation, at least those who assume they are going to survive.
When my high-rise office building had a fire and we could see black smoke billowing outside our windows, so we knew this wasn't a drill, the first thoughts in my mind were, "Okay, I need to leave fast. What will I
need when I get out?" I grabbed my cell phone and my keys, which I always keep right near my computer mouse anyway, and then evacuated promptly. Had I not been at my desk at the time, I would have had my phone in my pocket and would not have gone back to my desk. It was a good thing that I brought my phone because after 12 flights of stairs, the stairwell lights were completely out (including the emergency lights), and I used my phone, and instructed others who were panicking to use theirs, as a flashlight for the last 12 flights. We have one lady in our office who always wears super-high heels, and she was actually trying to go all down the stairs without taking them off, plus carry her coffee cup.
When the fire alarm went off in my condo building (turned out to be a little smoke on the floor below me, but no fire), I ran and grabbed the two cat carriers from the closet, shoved my more mellow cat into his carrier, chased the other cat and dragged her out from under the bed to shove her into her carrier, grabbed my purse over my shoulder, and ran down 7 flights of stairs carrying those two spoiled cats. Man, my legs were tired afterwards! But it did make me smile to realize that my instincts were to save my cats.
What it comes down to is that things can be replaced, but lives cannot.
