It's emergency preparedness week in Canada, and I received a link to the Canadian Government "Get Prepared" web site. Most information is the usual stuff about 72 hour kits, what to do when the lights go out or the water is rising, etc.
More interesting is a pdf on the site called
Basic Rescue Skills, for first responders.
It includes basic stuff on safely entering collapsed buildings, use of levers and cribbing, building shoring, hoists and jacks, etc., Though it's introductory, it goes beyond anything I've seen available on line before.
