For example, in homes with coal stoves, burning coal in winter produces carbon monoxide, especially if doors and windows are closed and there is no air circulation. Direct-vent gas water heaters vent combustion gases directly into the room or are not vented to the outside. Prolonged use, unauthorized modification, or the use of counterfeit gas stoves results in incomplete combustion, producing exhaust gases containing carbon monoxide. Carbon monoxide leaks at the factory, due to careless maintenance of gas lines or a lack of precautions during servicing, can also cause these emissions. In underground garages and industrial buildings, blocked ducts and chimneys prevent air circulation. Finally, using a charcoal barbecue to grill food can generate a significant amount of carbon monoxide.
