HAZARD with CBN wheels ()

Reed Gray
I think I may have had some smoldering with my old aluminum oxide wheels, but that was more than 10 years ago. I don't think I ever have much build up though, or sparks. I was sharpening yesterday for a demo, and when done and loading the grinder, I noticed round dots on the wall where the sheet rock screws were. The particles are magnetized some how with the grinding process. I have noticed this before whti some 'fuzzy' tools that I left down by the grinder as I sharpened. I have a big belt sander (1 1/2 hp, 6 inch wide belt), and get shavings/dust up to 1/4 inch thick some times. Never saw any fire or embers.
