CO alarm causes - carbon monoxide alarm sound cause

Beware that the production of dangerous carbon monoxide gas in a building is usually not constant - it can start and stop. So even if someone tests and does not find CO gas present, especially if your CO alarm has been sounding, you can NOT assume that conditions are safe in the building, and further expert visual inspection of heating equipment, chimneys, etc. are in order. For example ...

Carbon Monoxide in automobiles & gas engines – Sensorcon ...

Carbon monoxide (CO) is a highly toxic gas produced when fuels burn incompletely. The typical internal combustion engine used in most cars and trucks, can produce extremely high concentrations of carbon monoxide. Changes in engine design, fuel, and emission control devices have dramatically reduced the emissions of carbon monoxide. Still, operating a motor vehicle introduces risk from carbon ...

CO sensors can become saturated with target gas CO. If enough CO enters the sensor beyond maximum range (that listed in the instruction manual), the sensor is unlikely to be able to process all applied gas. When this scenario occurs, the electrolyte becomes saturated. A saturated sensor will continue to show high gas readings until the gas can be processed from the electrolyte. If saturation ...
