Potential deadly hazard warning

I'm sure most of you have used "brake clean" in some form/brand over the years.

Ever sprayed a little shot near say a hot manifold, and had a puff of smoke come off it and caught a whiff?  Then had a horrid chlorine taste in your mouth?  You might have already been exposed, and possibly been damaged by it.  I'm pretty sure I have.  As most of them are of the chlorinated variety (they're the only ones that really work!) - this article might just save your life.

Ouch

That is a little disturbing, but it makes sense: Refridgerents ALL break down into phosgene gas with heat, and many aerosol sprays have some form of refridgerent in them (Hence why when you shoot your can of spray paint or computer cleaner, the can gets cold, as the remaining refridgerent expands and pulls in some of the outside heat). Wouldn't have thought there would be a sufficient amount to be worrisome, but then again, I suppose mustard gas is mustard gas. Thanks for the link, Doc!

That is true, I had forgot about that. Still, much more pronounced with refridgerents I find. Hair spray cans, for example, don't get as cold from spraying versus something like computer parts cleaner cans or carb cleaner cans.

I've also heard that A/C manufacturers are looking into CO2 (Carbon Dioxide) in place of refridgerents, which could be interesting (Major hurdle is that unlike changing refridgerent, CO2 is not backwards compatable, due to pressure differences).
