question about sandstone et al

["Luba Gudz" <Luba.Gudz@zzzzzzz>]

Hello,

Relatively new here, have been reading and learning much from the list,
hoping that I'm following"list etiquette" correctly. My work is is
mostly small relief  in sandstone, marble and limestone, with majority
in a variety of sandstone, using power tools generating large amounts of
dust. Question about sandstone - from reading the list archives and many
posts, I am now very cautious working with sandstone (favorite stone).
My respirator has a 1 micron filter, but I work in a 24 x 24 ft garage
attached to house. I imagine that all those unseen silicate particles
are still hanging out after I'm done carving, and every time someone
walks through or picks something up, the unseen (and seen) particles get
stirred up and are a problem. Trying to figure out a reasonable and safe
set up here. It seems that a dust collection system with a 1 micron
canister filter would be the thing to do, with a hood pointed directly
at my work station, and to work with the garage door closed (preferable,
because garage is only 50 ft from the sidewalk on a small suburban
street, facing the street) I've also seen an air filter that can be
mounted to the ceiling which can be left on for a few hrs after work is
completed to pick up those stragglers. This combination of things,
respirator, dust collector, air filter - is this this a good set up or
not enough? When it comes to safety I'd rather be too careful and I
appreciate any advice on this, thanks. - Luba
