Learn the basics of leveraging and cribbing from our friends at SFD. These techniques could help you rescue someone that is trapped under heavy debris.
Fun fact, you can use the same cribbing methods to safely move heavy machinery and other objects without people underneath. Capturing lifting progress with cribbing is the safest way to raise vehicles for maintenace too. (I gave away my jack stands long ago and use 6x6, 4x4 etc cribbing and horizontally placed car and truck rims. Nothing is going through those.)
