What safety device should be included with all gas appliances to detect harmful gases?

The inclusion of a carbon monoxide detector with all gas appliances is essential for safety due to the properties of carbon monoxide (CO), a colorless, odorless gas that can be produced during incomplete combustion of fossil fuels, including natural gas. Carbon monoxide is highly toxic and can lead to serious health issues, including poisoning or even death if inhaled in sufficient amounts.

Installing a carbon monoxide detector provides an early warning system that alerts occupants of the presence of this hazardous gas, allowing them to take necessary action to ensure their safety, such as evacuating the premises or ventilating the area. This device is crucial in environments where gas appliances are used, as it enhances safety by monitoring air quality continuously.

While smoke detectors are important for detecting smoke from fire hazards, they do not address the specific risks associated with carbon monoxide. Hydrogen sulfide alarms and natural gas odorants also serve specific purposes but are not universally required across all gas appliances, making the carbon monoxide detector the most relevant safety device in this context.
