Gas Furnaces: Cracked Heat Exchangers. The most common reason for a natural gas furnace to leak carbon monoxide is from a crack in the heat exchanger. The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited.
The risk of carbon monoxide poisoning increases after disasters when gasoline- or diesel-powered generators may be more frequently used to supply power.

The CDC recognizes this hazard and offers Clinical Guidance for Carbon Monoxide Poisoning After a Disaster.
