: George is good at stirring up the fires, which in the long haul (hull) is
: good for us all. We need him. There's been more than once when I agree
: with his viewpoint, but posting a more tactful message doesnt generate the
: discussions that he does. And discussion is what we are about here. That
: said, let's do draw the line at direct insults, shall we?

: My definition of "adequate" is that if I can smell the fumes, it
: isn't. I'm in a 35 x 40 shop, and will have the slider door open if I'm
: glassing. For little batches, I use the radial arm saw hood, which
: exhausts outside. In general industrial ventilation (which is what we do -
: see www.benzco.com ) "adequate" means keeping a clean airflow
: across the breathing space of the occupant. This may be a hood, or a
: source-capture arm, or an air change. If the latter, I'd suggest a
: 5-minute air change at least. If you can arrange it so the fresh air comes
: across the breathing space, then you can get by with quite a bit less. All
: the source-capture arms run in the 500-600 CFM range. For a commercial
: builder, this might be a good alternative to the respirator. See the
: Nederman link from our manufacturers page. A 7' arm on a standard bracket,
: with a fan, runs in the $1700.00 range. A boom for it is quite a bit more
: than that.

Hey there Don, I think your definition makes sense. I do not see a direct insult in my post to George. A direct poke maybe. The fires he stirs are usually the result of direct insults or insinuations on his part, with most of the response to his abrasive manner. For him to imply from Systems 3 information that a closed garage door is adequate ventilation is generating misinformation and conflict where none exists. For him to blithely go around drumming up liability issues around others businessess and livelihood is equally destructive and unnecessary.
