I remember reading an Arthur C. Clarke book where a space liner has lost their engines and their airlocks. The protagonist on the military rescue ship decides to do something drastic: blow up the space liner. They seal the people into groups of 20 in separate cabins, and then they detonate small charges to puncture each cabin at a time. Their ship is positioned right next to the liner, with utility cords leading straight to the airlock. Clarke took this opportunity to explain that you don't freeze and explode in space, losing oxygen is the main problem. But also for that reason--- don't hold your breath when you're about to be exposed to vacuum, that's just a good way to rupture your lungs from the pressure.
