What is a significant danger associated with gas appliances if not properly maintained?

Carbon monoxide poisoning is a significant danger associated with gas appliances if they are not maintained properly. Gas appliances, such as furnaces, water heaters, and stoves, can produce carbon monoxide as a byproduct of combustion. When functioning correctly and maintained regularly, these appliances vent carbon monoxide safely outside. However, if there are issues like blocked flues, faulty combustion processes, or poor ventilation, carbon monoxide can accumulate indoors. This colorless, odorless gas can be extremely harmful, and prolonged exposure can lead to serious health issues or even fatality.

The presence of carbon monoxide is particularly dangerous because individuals often cannot detect it without a properly functioning carbon monoxide detector, leading to the potential for severe health risks. Regular maintenance ensures that appliances operate safely and efficiently, significantly reducing the risk of carbon monoxide exposure.
