One of the guys at the shop where I work had an "incident" with the hydraulic press. He's an experienced welder and has used the press many times before.
"Bob" was using a 25 ton hydraulic press to straighten out a 1-1/2" thick stainless steel weldment. Although told and shown the proper way to do it, he got lazy / sloppy and had one of his blocks crooked that was being pressed down.
He was lucky the piece that went flying was aluminum and didn't have much mass. He ended up with stitches / staples and was extremely lucky he didn't incur any serious injuries.
Below will be two pictures, one of his hand which got three stiches and the more graphic one of his head in which he acquired six staples. He better hope he doesn't go bald
Remember folks, machinery has no conscience, no soul or feelings and doesn't care what is in the way.
