We had a two can Red Devil shaker at work. Some desk jockey figured it was too dangerous, so we had to have a big expanded metal box put around it. Apparently, it was still way too dangerous, so it had to be dismantled and sent off to surplus. Now we have stir sticks. Probably the same guy who had the power cord cut off the Powermatic because it didn't have the same guarding as the cheap Chicom POS that replaced it. We blew over $100k on machine guarding a few years ago, sometimes to cover a 3" length of spinning shaft you would have to climb 3 ft over a 400F hot piece of machinery to touch with a fingertip.
