Step 22Grinders are Dangerous

Grinders are Dangerous
A few days ago I was using an air-powered grinder and "BANG!" PAIN IN MY BELLY.
I didn't want to look. Scared to death I gimped into the next room yelling "check me!". I thought I'd be bleeding and maybe disemboweled.
Here's what it looks like.
The grinding wheel had broken and threw a piece that hit me in the gut.
Another piece hit the wall, making a sound like a gun.
If I'd been hit in the face or the eye, I hate to think what would have happened.
The piece that hit me did this damage through two vests, a shirt, the top of my pants, and belt.
I guess that's why they want you to leave the guards on the tool and wear a grinding mask.

 My  cousin got a chunk of grinding stone to his face a couple years ago. It leaves a biiig gash and needs some stitches. Not fun. I have never used one without a mask since.

I had the same happen with a sanding disk on a rotary sander. I had some stitches in my chin... I had the opposite reaction: "that was odd... but it was a piece of sand paper so there's no way in hell it could have hurt my face from that far away"
