Abstract
A gas generating composition containing glycidyl azide polymer and a high trogen content additive selected from the group consisting of guanylaminotetrazole nitrate, bis(triaminoguanidinium)5,5'azotetrazole, ammonium 5-nitraminotetrazole and high bulk density nitro guanidine generates large quantities of nitrogen gas upon burning and can be used to extinguish fires.
