my room-mate in college made a short bench that was only long enough to support the shoulders and upper back. If you got stuck you just sat down on the floor and the weights would roll down the stomach to the floor.
I just don't put collars on the bar, so I can tilt it and let the weight slide off one side, then the other. It doesn't sound like that would have saved that kid, though, sounds like he dropped it on his neck rather than just failing the lift.
