No, standard carbon monoxide (CO) detectors cannot detect e-cigarette smoke. CO detectors are designed to detect the presence of carbon monoxide, a colorless, odorless gas produced by incomplete combustion. E-cigarettes, on the other hand, produce aerosols (vapor) from heated e-liquids, not combustion, and therefore do not produce the gases that CO detectors are designed to identify.
Here is a more detailed explanation from anka security:
Carbon Monoxide Production:
CO is a byproduct of burning materials such as wood, gas, or fuel. It is a dangerous gas that can be deadly in high concentrations.
E-cigarettes and Aerosols:
E-cigarette devices heat a liquid (e-liquid) to create an aerosol, which is then inhaled. The process does not involve combustion, and therefore does not produce CO.
Sensor Differences:
CO detectors use sensors that specifically detect the presence of CO gas. These sensors are not designed to detect particles or chemicals in e-cigarette aerosols.
Smoke Detectors vs. Carbon Monoxide Detectors:
While some smoke detectors may be triggered by e-cigarette smoke due to the presence of particulate matter, they are different from CO detectors. CO detectors are focused solely on detecting carbon monoxide.
