pwood,
How small is a ' small one man shop '? Is the ' one man ' operation "mold blowing" or
" free blowing" the glass? Is it a small production type facility, or a mass production
type? A small operation might be classified as a Type "B" occupancy [ Section 304.1
in the `06 IBC: "Training & skill development not within a school or academic
program" ]. If the ' one man ' operation is mass producing and selling the
products on site, then maybe an F-2 / M / B.
Requesting some more info from you... The glass furnace would be ventilated per
manufact. requirements, if there are any available, otherwise Section 301.3 in the
IFGC. The rest of the space could be ventilated like a Type "B" occ. space.
