I think this guide is unnecessarily pessimistic about surviving the blast. A dedicated fallout shelter building will survive 20 psi overpressure, and being away from windows will save you from the third degree burns and flying glass that do a lot of the damage in explosions. Also fires will start: if you live in the Berkeley Hills, this can complicate your situation tremendously.
