In many documented tragic residential CO incidents the source of the CO has been a malfunctioning furnace / flue system - not a typical fire condition. The CO detector is the only detector able to detect this deadly gas condition in these instances. CO gas is odorless, colorless and deadly. CO gas is typically discharges hot causing it rise to ceilings, even though it is of almost identical density to air, the reason why ceiling detectors are my first choice. I advocate using

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 compoun
