Answer :

A carbon monoxide detector does not detect natural gas; it specifically monitors for carbon monoxide, which is a tasteless, colorless, and odorless gas that can be lethal if undetected.

Carbon monoxide is a colorless, odorless gas produced by the incomplete combustion of fuels such as natural gas, charcoal, or wood. Detecting CO is crucial because, unlike natural gas which typically has a sulfur-like odor added to it, carbon monoxide is undetectable by human senses.

While natural gas detectors do exist, they function differently from carbon monoxide detectors. For comprehensive safety, it may be advisable to have both types of detectors in a home, especially in areas where fuel-burning appliances are used. Natural gas detectors alert to the presence of methane and other gases usually found in the domestic supply, whereas CO detectors strictly monitor carbon monoxide levels.

No it does not as it's not built for that purpose.

Carbon monoxide is something that can't be smelt so that is very dangerous compared to natural gas because we give an odourant to it to give natural gas an actual smell so it's detectable by humans.
