I'm in a basement shop and hope to set up a dog bed for him to hang with me down there eventually (I'm still finishing the room and it's still chaos in there right now).
When I get organized I'm going to become anal about keeping things tidy (i.e. no kids allowed) and because I use the RCBS covered media seperator tumbler so I think the dust levels are under control.
IIRC, Richard Lee tells the story about a guy who had elevated lead levels and when they surveyed his shop the only place they found elevated lead was around the tumblers... and they were very high there. So I poor the tumbler into the seperator and quickly close it up. Then I let things settle b4 opening the seperator up. Still a little dusty, but much better than b4 I got the clamb shell seperator.
This room doubles as my wood shop, so I have a ceiling mounted air filter as well, which should help with airborn tumbler dust.
My only press is a LCTP, and with the 100% of the primers landing in the tube, I can empty the tube into a coffee can without ever handling them.
My only two problems are:
1. Dog is afraid of the basement stairs
2. Once down there he's likely to visit the cat's litter box for a snack
