I keep gooseneck prybars in my bedroom, office, car and one in a car trauma FAK - buy them cheap, and spread them around. I'm not shy about breaking out glass or wrecking a doorframe getting myself or someone out of a jammed door.

Then a couple 4-5 foot halligan type prybars in the outside storeroom, along with a garbage can full of sacrifical 2x4 and 4x4 blocks, for cribbing and lifting after a collapse. I put the garbage can on wheels, or it can be toted by two people. Ace Hardware stocks a really nice inexpensive model long prybar for ~$25, I buy one, they order another one, I buy another...

I put a 16 inch prybar in every 72 hour kit I build and give away - daughter #1 got one when she went to college, handy as a defense against unruly boys...
