Timely thread. I just went to the emergency room a few weeks back. Regular stuff, cut an exhaust pipe, and I was cleaning it up for welds with one of these:
I still have no idea what happened, but in a split second, the grinder was in my face. I had safety glasses on, but my nose got stuck between the wire wheel, and the guard on the grinder at full throttle. It hit me so hard, I was stunned, and when I came to, and looked down at my yellow work shirt, it was dripping red,. I knew I was in trouble.
I washed it out, and took a look in the mirror, and I when I could see bone, I knew I was going to the ER. 6 stitches and a few weeks later, I'm doing o.k , but have a new found fear of the grinder.
I bought a full face mask the next day. I use these things all the time, I was lucky it did not go into my eyes.
Be careful friends!
