Gas leaks FAQ

Technically speaking, a carbon monoxide detector is not designed to detect the presence of gas. Instead, these devices alert for elevated levels of carbon monoxide in the air that could be the result of toxic gases or air quality issues.

Can a gas leak trigger a carbon monoxide detector?

Ultimately, no, a carbon monoxide detector cannot detect a natural gas leak. Carbon monoxide (CO) is a toxic gas created when fuel is burned in the presence of low levels of oxygen. Carbon monoxide is very different from methane and cannot be detected with the same sensor.
