I've got a big crowbar and a short hand saw in my above ground saferoom. I'm not sure that would let me get a blocked door open or not. Any other ideas on tools to escape when the door is blocked?
Does the door open outward? That'd be a tough one, but you might consider a hydraulic jack and a length of stout pipe with a base plate that you can brace against the door while using the jack against the opposite wall. In other words, turn the jack sideways.
If I got a storm room, I'd want one with an inward-opening door. Takes up more room, but I'd prefer that.
