Depending on the workpieces you do another suggestion would be a
guard of sorts, to direct ‘lost’ pieces from hitting you.
Years ago, as a favor, I was buffing a brass door knocker. The
buffer was big, about 3HP with a 12’ corrugated wheel. Piece snagged
and the wheel spun that thing right around and smacked me between the
eyes. I literally saw stars. Fractured skull. No, that’s NOT why I
am the way I am
A coworker once severely injured his eye when the chain caught on
the wheel. Someone had stacked some boxes behind where he would stand
to buff, he couldn’t even step back.
Anytime you operate machinery you must think safety first.
