Unless the "At Home" powdercoat is different than the industrial variety,
there are very little fumes, and I don't think they are hazardous.  I had
to customize a HUGE powdercoat oven that was approximately 50' x 50' and
10' tall with an overhead moving track running through it.  Parts were
sprayed in one part of the factory, then moved down the track into the
oven, where they wound back-and-forth several times before exiting to cool.  

The ovens were open on both sides and had no ventilation.  The heat that
spilled out of the ovens was circuilated to keep the plant warm in the
winter time.... I doubt OSHA would have allowed that if there were toxic
fumes.  As a side note, the ovens were heated with huge rows of gas-fired
radiant heaters (four tube heaters on each side of the track, about 30' in
length... plus the track weaved through 3 times, so there were 3 sets of
these).  The 24 radiant heaters were fed with a 2-1/2" natural gas line and
produced some ungodly amount of heat (500M to 750M BTU?).  We installed the
radiant heat, replacing open-fired burner logs - 30' burners on each side
of the track with 18" tall blue flames coming out of them :)

Man I'm glad I don't do HVAC work anymore... after being turned off for 24
hours that oven was still about 120*F - 150*F inside...
