Sometimes when you're in a large fire, you can sneak inside a building even though technically you would otherwise have to break down a front/back door. During this emergency, if you want to save a sim you need to break down a series of doors leading between them and the outside world before you can convince them to run and they count in the number of sims whose lives you have saved.
A couple questions, if you'd all be so kind:
1) Has anybody found a way to fail a fire? I'm at level 10 in the career right now and, if I go home, my alarm keeps ringing and sending my sim to the fire even if it's literally unwinnable (note: for some fires, you may actually want to have the demolition skill handy).
2) Has anybody found a way to 'force' a particular disaster, aside from outright modding the game? I have gotten the criminal disaster several times, the gnome one and quite a few earthquakes, but still have never seen the x-ray disaster or whatever one may or may not exist at the science facility.
Ahh, the dangers of completionism...maybe I should have just stuck with architectural design.
