How Does Fire Retardant Do What It Does?

Hi all,

Just saw a prog about how they make fake leather fire retardant !!..I know ..I know !!...I can tell you're all jealous at my Bohemian Lifystyle !!

Anyway....what they did not say was how the retardant works !! does it work ?

It passed the test in that when set alight it had to extinguish itself within two did...that's nice !!

Men are the same as women, just inside out !

I don't know for sure, but I imagine that the fire-retardant is some chemical which thermally decomposes (i.e. when it gets hot) to release a gas which smothers the fire (by displacing the oxygen). Guess the gas might be CO2 (or HCl ?), but I'm sure Wikipedia or some other site can fill in the details...
