Hi. Was just noticing a little piece of paper that was in the Tamiya Abrams kit that I'm working on, issuing a warning about making sure to only use the plastic spure(s) marked with a >PS< in making anything with the stretched spure method. And on looking these spures over I noticed that only two of the 4 or 5 spures in the kit are labeled as such. Then they go on to say that using other spure(s) can give off a posionous gas if heated.

I would assume that all the plastic spures are made up of the same chemical combination, so if one wouldn't give off a posionous gas, the others shouldn't either.

The only thing I can think of is the 'rubber type' of spure in the kit that holds the poly caps. This, I would assume, would be the one they are talking about giving off posionous gases if it were to be heated.

Anybody else run across this particular warning label in their kits? Just curious here, as this is the first time I think I've ever seen this in a kit before. Just was wondering what other's take on this is. I would have to imagine it's lawyer thing, as kids do work with these kits, and could heat whatever their hands happen to first pick up to make stretched spure out of, and Tamiya is just trying to cover all the bases.

Take care, Sgirty

Yes, I've noticed it on some Tamiya kits. Seems to me the Churchil and Cromwell but I could be wrong. I haven't checked to see how many of the sprues aren't marked PS.

Good heads up.

If I'm not mistaken the rubber sprues are made of a poly vinyl chloride derivative. This would give off Chlorine gas upon heating... not a good thing.

The plastic sprues of polystyrene are perfectly safe... so no problems there. :-)

All plastic resin fumes are a hazard to your health. Styrene isn't too bad, when stretching sprue, unless you get it smoking. However, some of the othey types will release really nasty fumes when heated. ABS is one that will give an instant headache from just a slight whiff. I don't know if any of the model producers are using an ABS blend, but Testors model cement is now good for styrene and ABS.

Chlorine gas was used during wwi mmm nostalgic LOL!

mmm the nostalgia, tis choking me to death!

actualy it burnt the lungs and other vital organs mmm the feeling of clorine gas in the good ol lung

I think the Germans used this in Auschwitz, they dropped it from the top of the chambers, and `and they knew they were done when they stopped hearing the screams, so yes, this stuff could be dangerous. oh, isn't humanity beautifull? I'm sure god ain't laughing :-)

Isn´t everything hazardous to your health in high enough doses?
Everything that burns creates gases that are potentially dangerous.
Paint and glue fumes aren´t exactly healthy
If you got proper ventilation I wouldn´t bother too much about this.
But that´s just me.
