I have worked with a table saw for years doing construction. I will agree with bladesmith the guard with the anti kickback pawls are usually the first thing to go. In my opinion, the design of most will cause as many accidents at they prevent.
Having said that I will say I have had several close calls over the years. I had a blade catch a piece of thin wood and shatter it. Hitting my hand like Pages, however I will say I think his looks worse!

It was my fault I should have readjusted the blade height for the thickness of the piece. So I also have to agree with Randy somewhat,
this wasn't the wrong tool but it was the wrong way to use that tool, but I did it anway becuase I had got away with it before!
The worst one I got was last year. While cross cutting a piece of ¼" plywood it begin to bind and even though I could see what was happening I couldn’t stop it. The piece after binding began to try and turn around pushing up over the crosscut slide and when I clamped down on it that much harder it an attempt to stop that, it exploded!
The blade propelled a chunk back at me. Catching me in the stomach, it hit so hard it actually knocked the breath out of me.
lucky it hit me crosswise and not endwise cutting it into my gut. I wore that bruise for months. Once again it was my fault for not adjusting the height of the blade for the material.
Those type of accidents happen because you get
complacent and in a hurry. Over the years I have probably got away with doing that one thing I knew was wrong and twice it cost me. But luckily I am still around to talk about it, and I don’t plan on a third. I now stop and readjust the height to make that one quick cut.
Page I am sorry you got hurt but like myself, when I look back at my last accident I realize it could have been much worse and hopefully unlike me, it won't take a second time to get thru to you. A power tool is inherently dangerous and misuse increases that danger, ten fold! By the sound of what you are saying happen this right here may have stopped your problem from happening a push stick! Check out this page. You always want to push the piece between the blade and the slide thru and out beyond the blade.

Don't forget about the cutoff as if it vibrates back into the blade it too becomes a missile also. On that page you will also see a wide push block. That can and will stop both things from happening. But never forget you are going to have to reach over the running blade and hold it till all movement has been stopped. Like I said power tools are inherently dangerous!
