I knew about the grinding and potential metal shavings in the eyes causing problems.
When I went in to find the cause of my neck and shoulder pain, I asked if I needed to change clothes into one of those expensive fancy paper gowns with rear air conditioning. The two running the machine that day said no as long as I hadn't been working that day. :sign0020: Ok.
So on the table I go to get scanned for 20 minutes of excruciating pain.
When I finally got up I saw the reason I should have changed clothes. Even though I hadn't been working in the shop that day and these were clean out of the closet, the massive magnet drew the minute grinder fillings out of the clothes I had on and were all over the table. Guess next time they'll have me change.
BTW the source of my pain was 3 herniated discs in my neck. Other than steroid shots or surgery to fuse them together (Neither option I wanted) there was nothing they could or would do. I opted for self home exercises to stretch the neck and relieve the pressure. Not a 100% but it helps.
