In case you did not notice I said for safety sake Jim, if you do not wish
to
use whatever then by all means don't!
But myself I would rather be safe than sorry. As for proof , GET THE MSDS!
See what it says. I have not read it but I am sure it can not be to good
for
ya! Have not seen to many man made chemicals that were.

Like others have said, polystyrene, no big deal;

polyurethane foam, very bad.

polyurethane foam breaks down into phosgene gas under the heat of a
hotwire. dont hotwire it. use a knife and surform planer, or
sandpaper.

Exactly Stealth Pilot!
The MSDS has all the info that one could need in order to make the proper
decision as to what he should wear for his protection or not,...and then of
course it will still be his/her decision as to if they want to follow what
the MSDS says. But the fact is , the MSDS has all that info, and it is not
guessing. So that is why my advice was to get the MSDS in the first place,
instead of opinions. My personal preference is I do not chance any of those
chemicals..I protect myself. To each his own.

Mr Dixon's insistence on the MSDS as the Revealed Word of God is, in
this instance, misplaced.

The MSDS only covers the material when used as intended. The intended
use of polystyrene foam is building insulation. The MSDS is COMPLETELY
SILENT on precautions for hot wiring it, although some common sense
precautions can be inferred.

Given the many sites devoted to hot wiring polystyrene foam, a common
practice in modeling for about 45 YEARS, I think we can rely on the
collective wisdom of the users - just this once.

It is not The Word of God, and nor is it misplaced, it is a sound starting
point. But as I said to each his own and shall leave it at that.

PS Hi Ryan how are ya!?

Speaking of facts, I thought it was cyanide not phosgene. I
remember that it is typical for victims of airline crashes who
survived the impact but succombed to smoke inhalation to have
cyanide in their bodies from the burning of the urethane foam
seat cushions. Urethane is fire resistant up to a point,
but when it goes, it really goes-- and it off gasses befor
it begins to burn per se.

And you think that you've done that? Phosgene gas? Is that the gas that
comes from the jeans of queer guys with a lisp after they fawt.

I took college chemistry, but that means absolutely nothing to me. Big
technical words are not information.

Ignoring your filth I will answer thusly: dictionaries are our friends;

phos•gene (fos‚jŽn, foz‚-) n.a poisonous, colorless, very volatile
liquid or suffocating gas, COCl2, used as a chemical-warfare compound.
[1805–15; Gk phôs light (contr. of pháos) + -gen�s -GEN]

Come on, your sarcasm isn't very constructive. Go ahead and google
phosgene if you've never heard of it.

Stealth Pilot gave all of the relevant information with the words
"don't hotwire it" and "phosgene gas." You probably didn't learn
about phosgene in college chemistry, but you might have in high
school history or current events. It's one of the poison gases used
in the trenches in WWI, and by Iraq against Iran in the 1980s.

It is (or was) also a common byproduct of some paint manufacturing.
I wonder if Phosgene produces cyanide when metabolized because I
am quite sure that I've read about cyanide poising being the
problem with hot urethane from multiple sources.

OK, so who uses polyurethane foam? The blue stuff I see hot wired is
polystyrene foam (Styrofoam (TM)) It gives off styrene which is not
healthy, but you have to get the wire way hotter than necessary to
cause it to break down into the nasty stuff.
