Benching, especially if going for max strength reps , even more if you are an idiot and use the suicide grip (named for a reason) is basically the move in the gym that has the highest chance to get yourself killed.

If you are alone don´t max, don`t use the clips for holding the weights on the bar ( for an easy roll of shame) and preferably have some safety bars, even if you will loose a bit of movement range.
