What is a common safety concern when using gas appliances?

Carbon monoxide poisoning is a critical safety concern when using gas appliances because these appliances often burn fuel to produce heat. In the process of combustion, if the appliance is not functioning properly, or if there is inadequate ventilation, carbon monoxide can accumulate in the living space. This colorless, odorless gas is highly toxic and can lead to serious health issues or even fatality. Proper installation, maintenance, and use of gas appliances, along with the installation of carbon monoxide detectors, are essential to mitigate this risk and ensure safety in environments where gas appliances are utilized.

While overheating of the appliance and electrical hazards are legitimate safety concerns, they are not as specific as the life-threatening implications of carbon monoxide exposure. Similarly, noise pollution, while a nuisance, does not pose the immediate health risks associated with gas appliances as effectively as carbon monoxide does.
