Since the walnut dust problem answered several questions I had here is another one.

NEOPRENE DUST

I created a vaccum to grind pads and it caught about 98 % of the particles. I supposed that over the years I ground 1000's of pads. We would grind pads on Thursdays so they would be ready on Friday. Some Thurs. we had at least 25 pads to grind. Cut and fit all during the week and grind on one day to get all dusted up. I used a mask on these also, but I can bet that I have lungs lined with neoprene.

I am like the X-smoker now telling all to stop making yourself sick.
