Fire Equals Toxic Gasses; Toxic Gasses Equal...

Fire is a chemical chain reaction.  It is the transformation of a “Fuel’s” heat released gasses in combination with oxygen while being in the presence of a heat source; resulting in ignition. Bear in mind that the air we breathe is 21% oxygen. Consequently  keeping the air out causes the fire to die. Fire causes the rapid reorganization of the chemical compounds that comprise the fuel, hence transforming the original chemical compounds into entirely different chemical compounds.  These new chemical compounds are
