Can carbon monoxide be detected by smell?

Carbon monoxide is a gas that is both odorless and colorless, which makes it particularly dangerous. Because it lacks a distinctive smell, individuals may not realize they are being exposed to it until symptoms occur, making it essential to have carbon monoxide detectors in homes, especially in areas where combustion engines or heating appliances are in use. The ability to detect carbon monoxide is crucial for safety, as prolonged exposure can lead to serious health risks or even be fatal without any warning signs. This characteristic of carbon monoxide emphasizes the importance of awareness regarding air quality and the need for detection devices rather than relying on the human senses for detection.
