Very much so, RAS- I don't care were you are, if you've got subways or commuter trains, you can get the windows and/or doors open without tools. Fire safety issue.

Yes, following the two or three steps on the sign labeled "in case of fire" isn't as dashing as smashing the window open, but it's liable to either be faster than trying to smash safety glass or less likely to induce major bleeding if you do get it open.
