Location: Waconia,MN | What are you guys using to collect the fine dust from sanding and what not. Didn't relize how flammable wood dust can be, just wondering what everyone else does to collect it and if anyone else is concerned of its flammability. |

| Oneida mini dust gorilla, shop vac, home made air cleaner using a large furnace blower and 3 furnace filters. The Oneida was grounded with thick copper wire as static and i suppose fire could be an issue. |

Location: Waconia,MN | What does it take to cause wood dust to ignite, in videos of demonstrations it's already a open flame or a red hot sparkler. Can it be ignited by a spark from say static? |

| Primarily, dust particles need to be suspended to cause combustion. Its like any other recipe for ignition: fuel, oxygen and spark. I studied this a lot in college concerning grain handling systems. Don't get me wrong, inert dust piled on the floor can still pose a hazard, but most fires come from dust that is suspended in the air in a large concentration and a ignition source is introduced. It could be an open flame or something like a hot bearing that causes combustion. It's easily avoidable, keep your shop clean and if your going to be creating a lot of dust, just make sure your shop area is well ventilated and try to minimize any obvious sources of ignition.
