Even the big commercial machines don't collect 100% of the dust produced from a planer / thicknesser or a standalone version of the two machines. The good thing about this though is that there is very little fine dust created which is the big worry from a H&S standpoint, leaving only being hit in the eye by a chip from the machine as the big worry.
I have a dust collection attachment for mine but don't use it as it's easier to sweep up at the end of the day.
Edit. Plus this way we can give the chippings to a local who keeps horsies to use for bedding.
I think you are right regarding the chipping sizes and lungs, but I did notice in the DC some fine dust in there too, so I put a respirator on just in case anyway.
