Can I safely do casting under a range hood close to the pot and vent the
output through a HEPA filter and recirculate the air in the garage? I could
vent outside but I'd rather keep the heat in the winter.
The vapor pressure of lead at the melting point is negligible, and one
of those metal screen grease filters will condense the vapor anyway.
The HEPA filter will also condense any vapor, and filter out the
I would not recommend working with lead around meal preparation areas. I've
done it in a
pinch but I think it was not the smartest solution.
How about the bathroom? It has an exhaust fan most likely.

Actually, I have a left over range hood when I put in a microwave over the
stove in the garage. I would mount it under the wall cabinets over the
workbench. NO WAY will I do this in the house. The garage is heated and
comfortable but if I just vent the hood outside it's going to suck a lot of
the heat out.
Yes indeed. I made one years ago for a guy that was allergic to
smoke..that simply bubbled the smog through a 35 gallon barrel and he
dumped it a couple times a year.

Heh, heh, I'm pretty sure my dog is a liberal - he has no balls.
I don't know the answer, but I wonder whether the lead you'll breath in, even
without filtration will be significant compared with the lead we all used to
consume until TEL in petrol was phased out.
Another option, more expensive but better, is to still use the range hood, but
pass the exhaust air through a commercial heat recovery ventilator. This will
get back 50-75% of the heat while dumping the fumes straight outside. I'm
planning to fit one of these to my workshop next year fro general ventilation
and also to the shed I'll be building for the boss to keep her pet rats in.
