While running the planer today the machine was loaded with static electricity because of the dry air. My dust collector has bag capacity of 5.4 cubic feet and of course it was on and swirling. I normally don’t empty the bag until it is about 3/4 of the way full. With that small amount of sawdust has anyone ever heard of any kind of combustion? I have always thought it would have to be a huge amount of dust for this to happen. Maybe grounding the machines would prevent even a chance of that happening. Anyway I’m rambling now. Any ideas? Thanks for reading.
