Hydraulic Press Accidents Vs. Ballistic Head

How dangerous is to crush stuff with hydraulic press if you don't have neccesary safety equipment? We are going to use our test dummy / ballistic torso to find out on this work safety experiment! Do not try this at home!! or at any where else!! We explode ball bearings, bearing ball, hammer, knife and brass cylinder in our safety box using 150 ton hydraulic press and 240 ton force sensor.
