re: Danger of sawdust combustion?

I don’t want to stir the pot but I don’t see any reference to back any of the argument in the wood nerd article.
Whenever I have an anonymous author I usually stay clear.

The argument that he never heard of even one explosion is probably true in his neighborhood. Maybe it should read his has never run across any data that document even one.

Like I said I don’t have grounding on my dust duct in my shop and won’t have any since everything is movable. In addition the flexible hose run is very short.
Having grounding will add a small complexity to my setup I am not keen on having at the moment.

When I get to have all my machines stationary I will definitely do that even just to avoid that unpleasant discharge.
