Fredf provides one of the best points. The dust collector would create a negative air pressure in the shop and it would require a fresh air intake. If a large enough air intake is not provided, the negative air pressure will pull air back down the flue for the hot water tank and the furnace if they are gas fired. This will drag carbon monoxide into the living space.

If fresh air is provided to prevent this it is not a problem.

I have seen pro shops and hobbyists do this and there is always a layer of dust all over the area. It gets on everything and I was put off by it but they seemed fine with it. Before I saw this I had considered doing the same.

In all reality, given the safety consideration you could always try it and see how it works with your equipment.
